Aaching the Camera to a Microscope
This camera uses a C-Mount standard lens mount. The camera can
be mounted directly to a microscope which provides a C-Mount
photo port, or it can be mounted to an ocular or photo port by
using an oponal compensang lens. The C-Mount standard uses a
1” (25.4mm) diameter with 32TPI (0.794mm pitch).
To mount the camera to a C-Mount port, simply remove the camera’s lens-port dust-cap, then align the microscope’s
port with the lens port. Rotate the camera in a clockwise manner unl it is rmly aached. The photo port on some
microscopes will have a rotang interface which can be locked and unlocked to change the orientaon of the camera. If
so, you can use this to properly align the camera to produce upright images. If not, you may need to unscrew the camera
slightly to achieve the proper orientaon.
To use a compensang lens, the correct lens must be used. A compable compen-
sang lens would have a C-Mount thread which would allow it to screw onto the
camera’s lens mount. The other end would be cylindrical, and would slide into one
of the microscope’s ocular ports or photo port. The compensang lens will have a
magnicaon such as 0.5X or 0.37X. When the lens has a magnicaon below 1X,
it is referred to as a reducon lens since it reduces the size of the image projected
onto the camera’s sensor. The magnicaon should roughly match the opcal for-
mat of the camera’s image sensor (see Sensor Opcal Format in the specicaon
tables). For example, if the camera’s sensor format is 1/2”, then a 0.5X compensat-
ing lens would be appropriate.
Aach the lens to the camera by aligning the threads with the camera’s lens port. Gently screw the lens into the port in
a clockwise manner unl it is rmly aached. Next, slide the lens into an appropriate port. Because of the camera’s size
and weight, it is beer to use a port on the microscope intended specically for cameras, such as a vercal trinocular
port. This will avoid pping the microscope, and can prevent the camera from rotang. Addionally, a sizing adapter
may be needed if the diameter of the lens’ tube does not match the diameter of the port. Some lenses will include sizing
adapters such as a 23mm to 30mm adapter.

Stand-Alone Mode
This HD series camera can be used in stand-alone mode when connected to a compable video display such as a monitor
or television. The camera’s controls and sengs are accessed using the supplied USB mouse.
Begin by aaching one end of the supplied HDMI cable to the camera’s HDMI port. Connect the other end of the cable to
the monitor’s or television’s HDMI input. The video display may need to be manually congured to use the correct input.
If so, consult the video display’s manual. Connect the supplied USB mouse to the camera by aaching its USB plug to the
camera’s USB port labeled “USB Mouse”. Next, connect the supplied power adapter by inserng its barrel connector to
the camera’s power port labeled “DC 12V”. The power indicator located above the power port should be red which indi-
cates the camera is receiving power. Press the camera’s power buon to inialize the camera. The power indicator will
change to blue. It will take several seconds for the camera’s soware to boot, during which a cursor will appear on the
screen. Once the camera is fully booted, you can move the cursor around the screen to acvate the on-screen controls.

ibility is subject to change. Before connecng the camera to a computer, install the soware to ensure the device will
be recognized by the operang system. More informaon regarding the soware is available in the soware’s help le
which can be accessed from the soware’s menu under “Help.”
The camera can be accessed from the computer using a USB connecon, wi-, or Ethernet. When the proper connecon
is made, the camera will be displayed in the soware’s list of available devices.
Connecng with USB
The camera can be connected to a computer using the provided USB cable. The cable has a type-A USB connector on
either end. Plug one type-A connector into the camera’s USB port labeled “USB Video”. Plug the other type-A connector
into one of the computer’s available USB 2.0 or USB 3.0 ports. If the camera is not already powered on, press the power
buon and wait for the power indicator LED to turn solid blue. If the AmScope soware has been installed on the com-
puter, the camera will be recognized as an imaging device, and can be accessed using the soware.

Image Exposure
Manual Exposure
Image exposure controls the amount of light captured by the imaging device. Exposure me is used to set the amount
of me over which light is collected. More me will result in a brighter image. For most stac subjects, increasing expo-
sure me to achieve the appropriate brightness is the preferred method. For moving subjects, too much me will result
in blurring as the subject’s locaon changes over me. Exposure me must be limited in these cases to prevent excess
movement. Use of the gain seng would therefore be the preferred method to achieve opmal brightness. Gain controls
the amount of amplicaon applied to the signal generated by the imaging sensor. While the signal strength would be
increased, noise generated during the imaging process would also be increased.
Auto Exposure
Auto exposure relies on soware to set the exposure me and gain. This simplies the workow, especially when captur-
ing images in changing lighng condions. As a microscope’s magnicaon changes, or the distance from the microscope
to the subject changes, the amount of light collected will also change. Auto exposure can connuously compensate for
these changes. This method assumes that the opmal amount of light would create an image with levels which would
average to a middle tone. Because of this, images of light subjects may appear too dark, and images of dark subjects may
appear too bright. For this reason, adjustment can be done using the exposure compensaon control, somemes called
exposure target. This allows you to increase or decrease the target level of brightness.
Color
White Balance
The color of an object is inuenced by the color of light reecng o of it or passing through it. Dierent light sources
produce light with dierent color-biases. Common examples are incandescent lamps which typically produce warm
colors compared to uorescent or LED lamps which produce cooler colors. This sort of bias is referred to as color tem-
perature. Due to this phenomenon, a white object may appear slightly yellow in morning sunlight, and slightly blue in
aernoon shade. To compensate for these variaons, digital imaging devices can process images using what is called
“white balance.” The white balance process shis colors based on the color of the light source, with the goal of produc-
ing a more neutral white or grey.
