Summary
This is a special heat dissipation glass which makes UV rays pass through and heat reflect. The heat-resisting cold filter (no occurrence of cracks or the like even at 500℃ for 100 hours) has the characteristics of inverted spectra together with the cold mirror, and reflects infrared rays by transmitting a visible ray. In addition, the production of a filter for the UV that reflects the invisible ray by transmitting the UV rays is possible. The cold filter is divided into CF-A type, CF-B type, and CF-W type in terms of the material of the substrate.

Use : Used for projectors, medical devices, and various light projector’s optical systems
