2)Tips and Attentions

(1)Do not touch the surfaces of optical instruments and elements with hands.Be careful when taking and placing the optical elements.Only the bases or non-optical surfaces are allowed to be touched.After the prism and plane mirror are used up,to avoid being broken,they need to be immediately put into the box and taken out again when they are needed.

(2)Avoid turning on and off the mercury lamp frequently.

(3)Adjust the optical instrument screw gently.Do not twist the locking screw strongly to avoid damaging the device.
