IR850nm IR PASS Optical Filter Glass

The optical performance of the quartz glass sheet is unique. It can transmit far ultraviolet rays, and can transmit visible light and near infrared spectrum. Because quartz glass is resistant to high temperature, the thermal expansion coefficient is extremely small, and the chemical stability is good. The bubbles, stripes, uniformity, and birefringence are comparable to ordinary optical glass, so it has a high stability optical coefficient when working in various harsh occasions. Essential optical materials.

Due to the unique high light transmission characteristics of ultraviolet light, it can be used in the protective glass in front of UVC deep ultraviolet lamp beads. The transmittance is as high as 90%, which is not achieved by ordinary optical glass.

According to its optical performance, it can be divided into three categories:

Far ultraviolet JGS1

Transparent in the ultraviolet and visible spectrum; no absorption band in the 185-2500nm band; strong absorption band in the 2600-2800nm band; non-luminous, stable light radiation.

Ultraviolet JGS2

Transparent in the ultraviolet and visible spectrum range; no absorption band in the range of 200-2500nm; strong absorption band in the range of 2600-2800nm; non-luminous, stable optical radiation.

Infrared JGS3

Transparent in the visible and infrared spectral range; no obvious absorption band in the 2600-2800nm band.

Our company can provide various thicknesses of quartz glass, and provide special-shaped processing, carving, opening, coating and other services.
