Laser protection lens

Laser protective lenses are also called laser window lenses and laser dust-proof lenses. They are mainly used to protect the focusing lens and prevent splashes from splashing onto the lens and causing damage to the lens. Regular replacement of protective lenses ensures the accuracy of processing.

Product features

1. High energy absorption: Laser protective lenses can efficiently absorb laser energy and convert it into heat energy, thereby reducing or blocking the penetration of laser radiation.

2. High transmittance: Laser protection lenses can block and absorb lasers of specific wavelengths while maintaining a high visible light transmittance to ensure the operator's visual observation and work efficiency.

3. Anti-scratch and chemical resistance: Laser protective lenses are usually made of high-hardness and corrosion-resistant materials, which can resist scratches and chemical corrosion and extend their service life.

4. Multi-layer coating: Laser protective lenses often use multi-layer optical coating technology to enhance its ability to reflect and transmit laser light and improve the protection effect.

Main effect

Protect the focusing lens to prevent splashes from splashing onto the lens and causing damage to the lens. Ensure the processing accuracy requirements by regularly replacing the protective lens. Coating the lens with a 1064nm anti-reflection coating with a high damage threshold (>15J/cm2) can effectively increase the transmittance of the lens, reduce energy loss, and improve the quality of processed products.
