99.9% Transmittance 133.5*2.5mm Laser Optical Lens Quartz For Laser Machine

99.9% transmittance 133.5*2.5mm Laser Optical Lens Quartz for laser machine

Description:

Protective lens is a very important precision component in the optical system of laser cutting machine. Its cleanliness has a great influence on the processing performance and quality of laser cutting machine.

Laser lens plays an important role in the laser system. The change of laser light path depends on the refraction of the lens

Advantage:

1. Complete standards → our company's laser protective lens are complex in variety and sufficient in stock to meet the needs of our customers; It has the characteristics of high Anti-damage threshold,Low residual reflection, Low scattering and Low absorption.

2. Processing coating → selecting excellent substrate, slicing, rounding, polishing, polishing and coating to make products; The protective lens is coated with high Antireflection film on both sides, which is stable and durable.

3. Other standard maintenance lens are all inclusive, and the variety is complex. Welcome to consult!

4. The primary function of YAG laser protection lens is to protect the focusing lens, prevent the spatter from sputtering on the lens and causing damage to the lens, and ensure the processing accuracy through regular replacement and maintenance of the lens. The 1064nm antireflection coating with high damage threshold (> 15J / cm2) on the lens can effectively increase the laser transmittance, reduce the energy loss and improve the quality of processed products. Widely used in: laser welding machine, laser cutting machine, laser marking machine and other laser equipment.
