ASSEMBLY INSTRUCTIONS
Read these instructions thoroughly before attempting assembly.The RZ is a modular system, and your
configuration might not include all of the parts discussed in this manual. This will affect the assembly
process, so be sure that you understand how your components fit together and the order in which they
should be assembled before you begin. Make sure that all exposed lens and prism surfaces on each
part are clean and free of dust before assembly.
(1) Unpacking: Carefully remove each part from its shipping container, and verify that you have received
all items on the packing list. It is a good idea to keep the packaging material, as it is useful for future
storage or transport.
(2) Microscope Body and Stand: The microscope body may already be mounted on the stand. If not,
loosen the set screw at the back of the body and slide the body over the vertical mounting post on the
stand. Make sure that both the body set screw and the safety collar set screw are well tightened. To
protect the microscope body from damage, remember to adjust the safety collar each time you raise
or lower the body.
(3) Objective: Screw the objective lens into the threaded opening on the bottom of the microscope body.
Be careful not to drop the objective or touch the exposed lens surfaces.

STANDARD BINOCULAR HEAD
The standard binocular head is inclined at 45 degree. The interpupillary
distance is adjustable from 46mm to 75mm.
ERGONOMIC BINOCULAR HEAD
The ergonomic binocular head viewing angle is adjustable from 10ﾟto 50ﾟand
the interpupillary distance is adjustable from 52mm to 75mm.
ADJUSTING THE VIEWING HEIGHT
The viewing height is correctly adjusted when your body, neck and back are
positioned to avoid fatigue and strain. In the case of the ergonomic head the
viewing angle (10ﾟ50ﾟ) can be adjusted by holding the eyepiece tubes and
swinging them upwards or downwards.
When using the standard viewing head the eyetubes are fixed and the viewing
height can only be adjusted by increasing or decreasing the height of your
worktable or chair.
ADJUSTING FOR SPECIMEN HEIGHT
Set the diopter adjustments to zero. Place a specimen beneath the
microscope objective. Zoom to the lowest end of the zoom range (7.5).
Loosen the clamp screw holding the microscope body on the stand while
supporting the weight of the body with your free hand. Raise and lower the
body while looking through the eyepieces until the image is roughly in focus.
Tighten the clamp screw.
FOCUS CONTROLS
The coaxial coarse and fine focus controls are located on each side of the
microscope body and can be operated from either side of the microscope.
The coarse focus control rotates a full 360ﾟand allows the microscope to
travel vertically over a distance of 50mm or 2 inches.

(4) Viewing Head: A basic RZ system will have the viewing head mounted directly to the microscope
body. However, If your system includes the COX Coaxial Illuminator or the MA751 Photo/Video
Attachment, these items must be installed before the head is mounted (see Page15 ). The dovetail
on the bottom of the viewing head (ergonomic or standard) fits into the mount on the top of the
microscope body. Loosen the set screw on the upper front of the body, and place the viewing head
into the mount. The guide pin at the back of the mount should fit into the slot at the rear of the
dovetail. Re-tighten the set screw to hold the head firmly in place.
(5) Eyepieces: Loosen the set screws on the eyepieces and slide them over the eyetubes on the viewing
head until they are fully seated. Orient the set screws downwards, tighten them, and set the diopter
adjustment rings on both eyepieces to zero (see diagram).

INSTALLING THE EYE GUARDS
Each eyepiece is provided with a protective rubber eye guard. Use of the
rubber eye guard protects the optical surface of the eyepiece from accidental
damage and prevents stray light from interfering with the image you are
viewing. The protective eye guard simply slips over the viewing end of each
eyepiece until it is firmly seated.
INSTALLING THE EYEPIECES
Loosen the set screws on the eyepieces and insert them into the eyetubes on
the viewing head until they are fully seated. Orient the set screws downwards,
tighten them, and set the diopter adjustment rings on both eyepieces to zero.
The dioptric range is from 5 to 5.
ADJUSTING THE INTERPUPILLARY DISTANCE
The correct interpupillary distance is achieved when the viewer observes a
single circular field of view when using both eyes to view a specimen. The
interpupillary distance is set by moving the eyetubes closer together or farther
apart. The interpupillary distance will vary from individual to individual.
Interpupillary distance range: Standard head 46mm 75mm, Ergonomic head
52mm 75mm.
DETERMINING THE CORRECT EYEPOINT
The eyepoint of the eyepiece is the distance from the eyepiece to the pupil of
the eye. To find the eyepoint or correct viewing position move your eyes closer
to the eyepiece until the image of the specimen and the entire field of view is
observed without restriction.
EYEGLASS WEARERS
If you are an eyeglass wearer and the rubber eye guards interfere with viewing
of the specimen then fold the eye guards back upon themselves to give you
more distance between the eyepiece and your eyeglasses.

PHOTOMICROSCOPY AND VIDEOMICROSCOPY
PARTS AND ACCESSORIES
The primary component necessary for photo or video work with the RZ stereo microscope is the MA751
Photo/Video Attachment. The MA751 allows you to take 35mm or large-format Polaroid photographs
of your specimens, or to display your specimens on a video monitor. If you wish to photograph
specimens while simultaneously displaying them on a video monitor, you can do so by attaching the
MA752 Auxiliary Video Attachment to the MA751 photo/video attachment. (Note: You must have an
MA751 to use the MA752.)
MA751 PHOTO/VIDEO ATTACHMENT
The MA751 Photo/Video Attachment contains a beam-splitter prism which redirects 80% of the light
that would normally go to the eyepieces into the vertical photo tube behind the viewing head. This is
accomplished by means of the beam-splitter slider control on the right side of the photo/video attachment
below the viewing head (marked “BI/PHOTO” and “BI” ). With the slider control in the “BI” position, the
microscope functions normally with 100% of the light directed through the eyepieces. With the slider
control in the “BI/PHOTO” position, the beam-splitter prism redirects 80% of the light through the photo
tube (and auxiliary video attachment, if installed) and 20% through the eyepieces. This allows you to
view the specimen through the eyepieces while also taking photographs and/or displaying the image on
a video monitor. (Further accessories are needed to attach 35mm or video cameras to the MA751; see
below)
INSTALLATION:
The photo/video attachment uses the same dovetail/guide pin/set screw mount as the viewing head and
coaxial illuminator, so follow the mounting procedure described on Page 5 and 15 to mount the MA751 to
the RZ body. Then mount the viewing head to the MA751 in the same manner. If you are also using the
COX coaxial illuminator, it must be mounted on the RZ body first. The MA751 then mounts to the top of
the COX, and the viewing head to the top of the MA751.

COX COAXIAL ILLUMINATOR
The COX Coaxial Illuminator directs light from a 6V 30W halogen lamp (replacement bulb: MA326)
down through the objective lens onto your specimen and increases the microscope magnification by a
factor of 1.5X. This vertical lighting is especially useful for viewing highly reflective surfaces such as
solder balls, integrated circuits, wafers, or magnetic recording heads, as well as for illuminating small pits
and other surfaces that would otherwise be in shadow. The MA762 quarter wave plate (ordered
separately) is required for use with the COX to reduce glare and reflection. The COX also has dual filter
slots that accepts these five optional filters:
MA754 LB100 clear blue
MA755 G533 clear green
MA756 Y48 clear yellow
MA757 ND2 neutral density
MA758 ND8 neutral density
If you have a transmitted light stage (RZT, RZBD, RZDT) the COX draws power from a socket at the rear
of the base. If you do not have one of these stands, you will need the MA651/05 (115V) or the
MA651/10 (220V) power supply to provide 6V 30W current to the COX.
INSTALLATION:
The COX mounts directly to the RZ body below the viewing head using the same dovetail/guide pin/slot
mount as the viewing head. If the head is already installed, remove it. Loosen the set screw on the
upper front of the body, and place the dovetail on the bottom of the COX into the mount. The guide pin at
the back of the mount should fit into the slot at the rear of the dovetail. Re-tighten the set screw to hold
the COX firmly in place. If your system includes an MA751 photo/video attachment, it should be
mounted in the same manner to the top of the COX (see Page15 ). If not, mount the viewing head to the
top of the COX. Finally, connect the COX plug to the socket either at the rear of the base or at the rear of
the additional power supply.

USING THE MA150/50 AND MA150/60 CAMERA ATTACHMENTS
Taking high quality photographs through a microscope takes a little practice, but the basic steps that you
will need to follow are really quite simple. First of all, it is important that your microscope’s interpupillary,
diopter, and illumination settings are properly adjusted (see Pages-in this manual). When this has been
done, the next step is to “parfocal” the microscope and camera.
PARFOCALLING THE MA150/60 35mm CAMERA ASSEMBLY
When you use the MA150/60 camera attachment there are actually three ways you can view the image
of your specimen: through the eyepieces of the microscope: through the camera viewfinder, or through
the focusing eyepiece on the MA150/60.
The word “parfocal” means that when the image of the specimen is in focus through one of the viewing
positions it is also clearly focused in the other viewing positions.
It is only necessary to have the image focused at the plane of the film (i.e. as seen through the camera
viewfinder) in order to take clear photographs, but when the microscope and attachment are properly
adjusted or “parfocal” to each other it is much easier to take sharp pictures. Follow these steps to ensure
that it is:
(1) Look through the microscope eyepieces, bring the image you wish to photograph into focus. Then
pull out the beam splitter knob to redirect the image to the photo tube.
(2) Look through the focusing eyepiece of the MA150/60 camera attachment. Rotate and adjust the
outer part of the focusing eyepiece until the center double crossline
on the framing reticle comes clearly into focus. At this point the
image of the specimen is in focus when viewed through the
eyepieces of the microscope and the image of the crossline is in
focus when viewed through the focusing eyepiece. The next step is
to bring the image of the specimen into focus through the focusing
eyepiece.
(3) Look through the focusing eyepiece on the MA150/60. If the image
of the specimen is not clear, you can bring it into focus by adjusting
the height of the MA150/60 camera attachment on the photo tube. The photo tube is threaded where
it mates to the microscope body, and its height is adjusted by screwing it farther into or out of the
body. To do so, loosen both the locking ring on the photo tube and the set screw that holds the
MA150/60 on the photo tube. This allows you to turn the photo tube and adjust its height without
having to turn the camera. Look through the focusing eyepiece while adjusting the height of the
photo tube. When the image is as clear as possible in both the focusing eyepiece and normal
eyepieces lock down the photo tube locking ring and the set screw.

together by a set screw: a small mounting flange that
fits over the photo tube and locks down with a second
set screw, and a larger upper tube with a threaded
end to accept the T2 adapter that is attached to your
camera body. To assemble these parts, first attach
the T2 adapter to your camera body. Next separate
the two halves of the MA150/50 camera attachment,
slide the small mounting flange portion over the
photo tube, and tighten the set screw. Then drop the
photo eyepiece into the open top of the photo tube.
Take the upper tube of the MA150/50 camera
attachment and screw it into the T2 adapter mounted

screw so that the entire assembly is stable.
The MA150/60 has a focusing eyepiece with a photo
sizing reticle built in. This enables you to focus the
image at the plane of the film more easily than if you
are looking through the camera’s viewfinder. Unlike
the MA150/50, the MA150/60 is a single-piece unit,
so assembly is slightly different. First attach the T2
adapter to your camera body, then screw the
threaded end of the MA150/60 into the T2 adapter.
Next, drop the photo eyepiece directly into the photo

The image you wish to photograph should now be focused in all of the eyepieces and at the plane of the
film.
The procedure is identical for the MA150/50, except you must use the viewfinder window located on your
35mm camera body to parfocal the camera attachment instead of using the focusing eyepiece. Viewing
the image of the specimen using the MA150/50 camera attachment is more difficult due to the small size
of the viewfinder window and the lack of 10X magnification that the MA150/60 focusing eyepiece adds.
CAMERA SETTINGS
The most difficult part of photomicrography is determining the proper film, aperture, and exposure for the
images you wish to capture. There are so many factors that influence the way your pictures will turn out
that it would be impossible to discuss them all here. Different cameras, different types of film, different
specimens, different types of illumination, etc. will require different settings to achieve the desired
photograph. The best advice is to experiment with your equipment to learn which settings work best.
Shoot several pictures of the same specimen using different aperture and exposure settings, and keep a
record of the settings for each frame so that when the film is developed you can get a feel for how
changing the settings affects the photograph. Try different brands and speeds of film. Learn how your
camera works. If you become serious about photomicrography, there are good books available from

camera to the MA751 photo/video attachment or the MA752 auxiliary video attachment. The
MA151/10 is a standard “C” mount with no projection lens (and thus no magnification factor) and
comes included with the MA752. All other “C” mounts have projection lenses of various
magnifications and must be ordered separately.
