CxL

The CxL is a laboratory microscope reflecting a modern design as well as the latest in optical and mechani-
cal advancements.
Designed for professionals as well as students, this microscope offers many features and functions for a
diverse set of applications.
Extra clarity and contrast is provided through a 360°rotatable Monocular/Binocular/Trinocular body
inclined at 45°.
The pressure die cast stand consists of Ball bearing ‘frictionless’ sideways focusing to avoid any loss in
motion.
The sturdy new stylish design provides comfort as well as stability.
The high powered objectives are spring loaded to prevent accidental damage to specimen slides.
The quadruple nose piece has a comfortable ribbed grip for easy rotation that also safeguards the turret
system against any damage. All positions are par-centered and par-focalised ensuring the highest level of
accuracy.
The ball bearing mechanical stage allows smooth travel over a 76 x 50mm area with spring loaded stage
clamps for retaining the specimen at the exact position desired. A 0.1mm verier scale provides accurate
location of specimen area.
The LED configuration is operational with an in-built rechargeable battery and charging circuit. The
battery will be charged with a direct input power supply of 110V-240V AC 50Hz/60Hz. This ensures
continuous operation even under fluctuation voltages.
Our Halogen bulb (6V-20W) has an average life span of upto 2,000 hours. Our LED has an average life span
of upto 100,000 hours.
The CxL comes equipped with a removable N.A. 1.25 Abbe condenser for brighter Illumination levels, and

1. A microscope is a precision instrument with delicate glass compo-
nents. Please handle with care.
2. Do not use the microscope where it is subjected to direct sunlight,
high temperature, humidity, dust and vibrations. ( For the operat
-ing conditions, see chapter 14. “SPECIFICATIONS”) on Page 24.
3. The microscope is ventilated by natural convention. Be sure to
leave enough space (10cm or more) around body when installing
the unit.
4. Arm handle is provided for carrying the microscope.
To prevent damage, do not hold the microscope by the stage or
observation tube.
Be sure to remove the specimen from the stage clip while
transporting unit to avoid damage of the specimen slide.
1. Clean all glass components by wiping gently with cleaning cloth provided. To remove fingerprints or oil
smudges, wipe with cleaning cloth slightly moistened with a mixture of petroleum (85%) and isopropa
-nol (15%).
Since solvents such as petroleum and isopropanol are highly flammable, they must be handled carefully.
Be sure to keep these chemicals away from open flames or potential Sources of electrical sparks - For
Example, electrical equipment that is being switched “ON” or “OFF”. Also remember to always use these
chemicals only in a well-ventilated room.
2. Do not attempt to use organic solvents to clean the microscope components other than the glass compo
-nents. To clean non-glass components, use a lint-free, soft cloth slightly moistened with a diluted neutral
detergent.
3. Do not disassemble any part of the microscope as this could result in malfunction or mitigated perfor
-mance.
4. When not using the microscope, ensure that the frame is fully
cooled before storing the unit in a dry locker or covering with a
dust cover (provided).
5. To clean the condenser/phase turret, fully loosen the securing
thumb screw (1) and remove the condenser then, wipe the front
lens of the condenser with optical cleaning solution (mixture
suggested above) and lens tissue.
The condenser can be re-attached by replacing the condenser in
its seat, tightening securing thumb screw, and raising condens-
er bracket to desired position.

Zig-zag motion (X) Spiral motion ( )
If the microscope is used in a manner not specified by this manual, the safety of the user may not be
warranted. In addition, the equipment may also suffer damage. Always use the equipment as outlined in
this instruction manual.
Your microscope had been engineered for a long and safe operational life with the least amount of mainte-
nance required. In general, routine maintenance is limited to keeping the microscope working parts lubri-
cated and optics clean. Always cover the microscope with the provided dust cover when not in use.
1. Cleaning the lenses:
To clean the lens surfaces, remove dust using a soft brush or gauze (compressed air dust cans are
ideal). For removing finger marks or grease, soft cotton cloth or lens tissue lightly moistened
with cleaning solution ( 85% petroleum ether and 15% isopeopanol) should be used. For cleaning the
optics, use xylene. Observe sufficient caution in handling xylene.
Cleaning Procedure:
Place the Objective and/ or eyepieces on a dust free surfaces (e.g. aluminum foil). All other optical
components to be cleaned should be as accessible as possible.
a. Blow all loose dust particles away with a dust blower.
b. Remove all water-soluble dirt with distilled water. If this is unsuccessful repeat using a solution of
diluted hand soap liquid. Remove any remaining residue with a dry cotton swab.
c. To remove oil, use a solution of diluted hand-soap liquid initially. If this does not produce a satisfac-
tory result, repeat the cleaning using a solvent (Optical Cleaning Solution 85% petroleum ether and
15% isopropanol).
d. Grease must always be removed using a solvent.
e. Cleaning is achieved by using a spiral motion from the center to the rim. Never wipe using zig-zag
movements as this will only spread the dirt. With larger optical surfaces (e.g. tube lenses) the spiral
motion starts initially at the rim before to the middle and is only then followed by a center to rim
cleaning motion. Normally several spiral wipes are recommended.
We recommend pure, volatile petroleum ether or Optical Cleaning Solution as explained in point 3 above.
Wipe using a spiral movement. Do not use a zig-zag motion!
2. Cleaning of painted surfaces:
Avoid the use of any organic solvent (e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted
surfaces of the instrument. Painted surfaces can be cleaned with a very lightly moistened micro fiber
cloth. Loose dust and dirt can be removed using a brush of soft hair used exclusively for this purpose.

The reflection mirror is designed to be used in out door observation settings wherein a power source is not
readily available. The mirror attachment makes it possible to use natural light to illuminate your specimen.
The microscope should be installed in any place that is not
exposed to direct sunlight. Direct sunlight reflection can cause
eye injury, or in some cases, blindness.
The eyepieces should be oriented toward the rear of the micro-
scope so that the reflection mirror receives unobstructed light.
To do this, loosen the observationtubeclamping knob and rotate
the tube 180 º .
1. Fit the reflection mirror in the window lens of the microscope
frame by aligningthemountingtab.
2. Remove the daylight filter because it renders the image
blue under naturallightconditions.
3. The reflection mirror (fig. 5) Should be pointed toward
anywhere with stray light. While observingtheimage through
the eyepieces, adjust the orientation of the reflection mirror
to capturestraylight.
A planar reflection minor is used normally. However, if the
brightness is uneven or the outside view is visible in the
image, use a image concave reflectionmirror.
Thestandard10Xeyepieces are clamped usingscrews.
1. Using allen wrench 1.2mm, loosen the clamping screw (1)
from the oculartube and remove it.
2. Insert the optional eyepieces into the ocular sleeve and
