功能

• This filter absorbs ultraviolet and visible light and transmits infrared light.
• It is used to extract infrared light from white light sources and as a filter for infrared alarms and night vision cameras.
• The transmission limit wavelength can be selected at a wavelength of 760~985 nm.
• If you attach an infrared transmission filter to a semiconductor image sensor without an infrared cut filter, you can use it as an infrared camera.
• Since a wide range of wavelength bands in the ultraviolet and visible ranges are blocked, it is possible to increase the sensitivity of infrared observation by inserting a filter into the imaging device.
• A reflective film type cold mirror (CLDM) is also available.
• * Cannot be used for high-power laser or high-energy pulse laser in the absorption wavelength range.
• * Anti-reflection coat is not applied on both sides.
• * The maximum transmittance is 90% or less due to the reflected light from the front and back.
