It is an optical filter that selectively transmits ultraviolet wavelengths (255 nm) while blocking light of other wavelengths (using a substrate from Gohsui Seiko Glass).
Applications in the ultraviolet region are on the rise. At Itsuki Seiko Glass, we have developed filter glass substrates in the 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 region, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to transmit only specific wavelengths using aspheric lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Given the limited substrates and deposition materials, is anti-reflective coating feasible? ■ I've heard that measurement difficulty after film deposition is high; can you accommodate this? ■ Is it true that controlling the thickness in the UV region is very challenging due to its thinness? 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 aspheric 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) Custom design and customization available for requested wavelength range We can design and coat according to the customer's desired 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, detailed drawings will be required. 4) Measurement instruments Rest assured that a measurement chart will always be attached upon shipment. 5) Cleanroom compliance The working environment is maintained in a cleanroom with the necessary cleanliness for each stage from coating to inspection, ensuring a thorough system against minor film defects (such as foreign substances in the film).
