It is an optical filter that cuts ultraviolet and infrared light while having a high transmittance in the visible light range.
A UV-IR cut filter is a filter that cuts light in the ultraviolet and infrared regions while having a high transmission rate in the visible light region. In other words, it is an optical filter that simultaneously realizes the properties of both a UV cut filter and an IR cut filter. By placing it in front of CMOS sensors or CCD sensors, it serves multiple roles, such as cutting out noise-inducing light, providing heat protection for various light sources, and preventing degradation of LCD components due to ultraviolet light. It is an excellent optical filter and optical thin film with multiple functions. Are you facing any of these issues? - Is it possible to cut both ultraviolet and near-infrared light? - Can a filter be made that allows visible light to pass while blocking IR and UV wavelengths? - I want to reduce noise light and increase the sensitivity of the sensor. Can I consult with you? - Is it possible to custom adjust the wavelength range that I want to transmit? - Is processing to chip size possible?

basic information
1) Features: Excellent visible light transmission characteristics and infrared blocking properties. Adachi New Industry's IR cut filter achieves an extremely small ripple in the visible light range, allowing for high transmission rates. Additionally, by forming a dielectric multilayer film, it is possible to design sharp transitions from the cut band to the transmission band and from the transmission band to the cut band. 2) Custom design and customization available for requested wavelength ranges. We can design and coat according to the customer's desired wavelength range. Control in the blocking range as well as the incident angle are also important factors. 3) Component support is also available. We can handle everything from substrate procurement to film deposition. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 4) Measuring instruments. We will always attach a measurement chart upon shipment, so please rest assured. 5) Cleanroom support. The working environment maintains the necessary cleanliness levels from film deposition to inspection, and we have a thorough system in place to address minute film defects (such as foreign substances in the film).
