11 steps used in polarized light microscopy

Polarized light microscope is a precise and valuable optical instrument. It is also an indispensable tool in teaching and scientific research. If it is damaged, it will directly affect teaching and scientific research. Therefore, it should pay attention to maintenance and care. When using it, you should consciously abide by the operation. Procedure.

(1) Check before use.

(2) The microscope should be fixed to the seat, which is not suitable for changing and moving the microscope. When moving and placing the microscope, the action should be light and vibration-proof to avoid damage to the optical system. When moving the microscope, you must hold the arm and hold the lens holder.

(3) All lenses of the microscope are verified and must not be disassembled by themselves. The lens must be kept clean. If there is dust, use a brush or lens paper to gently remove the dust. Do not wipe it with your hands or other objects to prevent damage to the lens.

(4) The microscope lens and other Accessories must be placed in the original accessory box and placed in a fixed position to prevent falling to the ground.

(5) Do not disassemble the microscope yourself or use the accessories for replacement.

(6) When the sheet is placed on the stage, the sheet coverslip must be upward and the sheet is clamped with a spring clip.

(7) When using a high-magnification objective lens, it is necessary to look on the eye and avoid observing the eye in the eyepiece to avoid crushing the sheet and damage the objective lens.

(8) When replacing the objective lens, be sure to hold the objective lens to rotate by hand. Do not directly hold the objective lens by hand to prevent the objective lens from rotating.

(9) When using the upper polarizer and the Bronze mirror, avoid pushing hard to avoid damage.

(10) When the instrument is damaged or the adjustment fails, do not twist it strongly.

(11) After the microscope is used, push the upper polarizer and the Bühler mirror, turn the coarse handwheel to lift the objective lens, leave a eyepiece on the lens barrel, turn off the power, and cover the instrument cover.
