Infrared (IR) Transmission and Absorption Filters (Laser Protection / Chalcogenide Glass)
Heat absorbing filter ＜ISK series＞
【Product】
This particular glass is designed to provide maximum transmission over the visible spectrum, while minimizing the transmission of infrared rays.
Because this glass is able to transmit ultraviolet rays, it can be used as an ultraviolet filter (depending on the type of filter).
【Application】
Laser safety glasses, heat protection filters, YAG laser blocking, medical filters

IIR-SF®1 is the glass consisting mainly sulfur and has high transmission in infrared range.
This glass is particulaly useful for cameras and sensors that operate up to 8-11μm. Furthermore, it is less expensive than crystals of germanium, etc., which are widely used at present.
IIR-SF®2 is the improved material based on IIR-SF®1. Transmission area is 1 µm longer than IIR-SF®1 and we achieved low-price without using germanium.
Our products comply with environmental standards of both Japan and Europe and contain no hazardous substances restricted by the RoHS Directive or REACH Regulation or those adversely affecting the human health and environment such as selenium and arsenic.
Our proven, state-of-the-art press forming technology allows us to mass produce simple to complex shapes, many of which cannot be produced by standard polishing techniques. Please consult to Isuzu with your required thickness, shape, size.
*IIR-SF®2 is the result of intellectual property of Kyoto Institute of Technology.
【Application】
Infrared sensors, security cameras, night vision, etc.
