Product Description
laser optical demonstration teaching equipment
Product Introduction
The principle of the laser optical demonstrator is very simple. The horizontal laser beam emitted from the helium-neon laser is reflected by a plane mirror and then turned 90° vertically upward, and then expanded by a beam expander to become a fan-shaped beam. The fan-shaped beam is split by the dielectric film. After reflection by the dielectric film beam splitter in the beam splitter (abbreviation: beam splitter), also known as the horizontal direction, the fan beam intersects the demonstration screen vertically, so that the beam track is displayed on the demonstration screen. After placing various optical parts on the optical path, various optical experiments can be done.

Maintenance and precautions
1.The instrument must use 220V, 50HZ AC power supply.
2. Do not touch the mirror surface of the beam splitter and the coating surface of other parts with your hands, so as not to damage the coating. Dust contamination should also be avoided.
3. Pay attention to protect the paint of Yan Shiping and dial, and do not scratch or peel off.
4. After the instrument is used, all optical parts and components should be cleaned with alcohol-ether mixture (the coating surface should be wiped as little as possible, preferably not), and placed in a dry place, preferably in a drying cylinder.
5. All diffraction sheets should be placed in a drying cylinder.
6. After the instrument is used, press the shield on the beam expander to cover the circular hole to prevent dust from falling on the plane mirror.
7. If the laser tube is replaced, the upper cover of the instrument base should be opened first, and the laser tube holder should be loosened. The laser tube should not be clamped too tightly. To repair the laser circuit, open the lower cover of
