It is a dielectric multilayer film filter that transmits visible light and reflects near-infrared light.
It is used as a near-infrared cut filter that adversely affects CCD devices such as video cameras. The optical characteristics, such as the wavelength position with a transmittance of 50%, transmittance, and cut wavelength band, can be set arbitrarily. (Do you have such challenges?) Is it possible to cut only the wavelength of near-infrared light? I want to allow visible light to pass while blocking the wavelengths of IR. I want to suppress light that causes noise and increase the sensitivity of the sensor. Can the wavelength range I want to transmit be custom adjusted? Is it possible to process it to chip size?

basic information
1) Features: Excellent visible light transmission characteristics and infrared blocking properties. Adachi New Industry's IR cut filter can achieve a very small ripple in the visible light range and a high transmission rate. Additionally, by forming a dielectric multilayer film, it is possible to design a sharp transition from the transmission band to the cut-off band. 2) Custom design and customization available for desired wavelength range. We can design and coat according to the wavelength range requested by the customer. Control in the blocking range as well as the angle of incidence are also important factors. We will design according to the characteristics of the substrate and the customer's requirements, so please provide the substrate type and wavelength range when inquiring. 3) Component support is also possible. We can handle everything from substrate procurement to film formation. It is also possible to cut to 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) Clean room compliance. The working environment is maintained in a clean room with the necessary cleanliness for each process from film formation to inspection, ensuring a thorough system against minor film defects (such as foreign substances in the film).
