It is a filter that efficiently cuts (reflects) short-wavelength UV (ultraviolet) light while allowing visible light to pass through.
What is a UV cut filter (ultraviolet cut filter)? It is a filter that cuts ultraviolet (UV) light while allowing visible light to pass through. In digital cameras, it is used to reduce chromatic aberration, and in liquid crystal projectors, it is used to prevent the degradation of liquid crystals and other optical components caused by the light from lamps (such as high-pressure mercury lamps), with the aim of cutting unnecessary ultraviolet light. Are you facing any of these issues? ◆ Is it possible to cut only the wavelength of ultraviolet light? ◆ Can a UV cut filter for projectors be coated? ◆ I would like to consult about the degradation of optical components. ◆ I would like to consult about filters that minimize the impact on the human body. ◆ Is it possible to custom adjust the wavelength range that I want to transmit?

basic information
1) Features: Excellent ultraviolet transmission characteristics Adachi New Industry's UV cut filter has an extremely small ripple in the visible light region, allowing for a high transmission rate. Additionally, by forming a dielectric multilayer film, it is possible to design a sharp transition from the cut-off region to the transmission band. 2) Custom design and customization available for desired wavelength range We can design and film according to the customer's requested wavelength range. Control in the stop band as well as the angle of incidence are also important factors. 3) Component support available We can handle everything from substrate procurement to film formation. 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) Clean room compliance The working environment is maintained in a clean room with the necessary cleanliness for each stage from film formation to inspection, ensuring a thorough system against minor film defects (such as foreign substances in the film).
