It is an optical filter that selectively transmits ultraviolet wavelengths (255 nm) while blocking light of other wavelengths (using a substrate from Hisashi Seiko Glass).
Applications in the ultraviolet region are on the rise. At Isuzu Seiko Glass Co., we have developed filter glass substrates (IHU series) that have a transmission limit wavelength in the ultraviolet range and improved weather resistance to ultraviolet light. Recently, we have successfully deposited dielectric multilayer films to create bandpass filters in the ultraviolet range, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to selectively transmit specific wavelengths using aspherical lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Is it possible to achieve anti-reflection with limited substrates and deposition materials? ■ I've heard that measurement difficulty after deposition is high; can you handle that? ■ Is it true that controlling the thickness in the UV region is very difficult due to its thin film? Based on our achievements in visible light, we can achieve high transmission rates in the ultraviolet wavelength range by controlling the deposition process. Additionally, by leveraging our ability to mold aspherical lenses and lens arrays in combination with our deposition technology, we can propose new applications.

basic information
1) Features: ■ Excellent wavelength selectivity ■ Sharp edge filter It has the characteristic of transmitting or blocking light with a steep change. ■ Symmetry Typically shows symmetry in both the transmission band and the blocking band, so when it transmits wavelengths below a certain point, longer wavelengths are consistently blocked as well. 2) Design and customization available for desired wavelength range We can design and coat according to the customer's requested wavelength range. Control in the blocking region as well as the angle of incidence are also important factors. 3) Component support available We can handle everything from substrate procurement to coating. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 4) Measurement instruments We will always attach a measurement chart upon shipping, 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 coating to inspection, and we have a thorough system in place for addressing minute film defects (such as foreign substances in the film).
