IR cut filter
An IR cut filter, also called an infrared cut filter, is a function that cuts infrared rays with optical glass attached to the lens. The IR cut filter function is active on glass and film.
Sunlight and lighting emit light of various wavelengths (colors), but the range of wavelengths of light visible to the human eye is limited. In the digital world, light information in a range beyond visible light is transmitted as electrical signals.
If the image is output without cutting off this infrared information, the image will look completely different from the colors that we humans see.
An IR cut filter (infrared cut filter) is a filter that prevents unwanted light from entering the sensor when shooting with a camera.
Although infrared rays are invisible to the human eyes, most cameras use IR cut filters because they react to CCD and CMOS and adversely affect colors.
The base material is glass/absorption glass/film, and after thin film processing, dancing processing is also possible.
Our IR cut filters have received inquiries from customers in Japan and overseas, and are used in various products.

Camera equipment
A function that temporarily removes the infrared filter installed in a digital video camera to enable night photography.
Surveillance cameras use an IR cut filter during the day to cut out the infrared rays contained in sunlight and incandescent light to capture color images that look the same to the human eyes.
CCD sensors and COMS sensors are sensitive to wavelengths around 1100 nm, unlike the sensitivity of the human eye, which does not detect light with wavelengths longer than 700 nm.
