Product description
Parameters

Features

Laser windows, also known as laser protection windows, are mainly used to block the splash of debris generated by the laser cutting equipment during processing, and prevent the splash from damaging the lens. On both surfaces of quartz glass, anti-reflection film with high damage threshold (>15J/cm2) is coated to improve transmittance, achieve high optical power, high anti-laser damage threshold, firm film, good finish, low absorption, etc. , the performance is stable and reliable.

Smart Recognition Filter
Neutral density spectroscopic film is also known as attenuator, ND mirror. It identically and uniformly reduces light of different wavelengths, effectively reduces light, and does not change the color of the original object. Therefore, it can truly reproduce the original color of the object. It has the advantages of wide band attenuation rate, accurate attenuation, insensitivity to incident angle and polarization state, solid film layer, scratch resistance and strong hydrophobicity.
