The Travelling Microscope KCX-182 is designed to measure small distances and displacements using optical magnification and calibrated mechanical movement.
The microscope allows the optical system to travel horizontally and vertically.
The horizontal travel range is specified as 22 cm.
The vertical travel range is specified as 15 cm.
The eyepiece includes a crosshair for aligning the microscope with a selected measurement point.
The 2X achromatic objective magnifies the observed target.

Working Principle
The Travelling Microscope KCX-182 operates on the principle of optical magnification combined with calibrated linear displacement measurement.
The microscope consists of an optical system mounted on horizontal and vertical travelling slides.
The optical system includes a 2X achromatic objective and a 10X eyepiece with crosshair.
The objective produces a magnified image of the target.
The eyepiece allows the observer to view the image and crosshair.
The microscope is moved until the crosshair aligns with the required reference point.
The corresponding vernier scale reading is recorded.
The microscope is then moved to a second reference point.
A second vernier reading is recorded.
The difference between the two readings gives the measured displacement along the selected axis.
Measurement Formula
Measured Displacement = Final Vernier Reading − Initial Vernier Reading
For a positive distance, use the absolute difference:
[
d=|R_2-R_1|
]
Where:
(d) = measured displacement
(R_1) = initial scale reading
(R_2) = final scale reading

Fine Positioning: Use slow-motion adjustment for accurate alignment.
Second Reading: Record the second scale reading.
Displacement Calculation: Calculate the difference between the readings.
Repeat Measurement: Repeat the measurement to assess consistency.
Record Results: Enter the measurements in the laboratory observation table.
Completion: Return the microscope to a suitable resting position.
Storage: Clean and store the instrument in its protective box.
