Products: VUV/UV Notch - Reflective Filters
|
Multilayer reflective filters are all-dielectric reflectors that offer high reflectance at specific VUV through UV wavelengths while transmitting longer-wavelength UV-to-IR light. Filters are designed for 45 degree AOI. Custom UV filters for peak wavelengths >250 nm are available with DUV-VUV transmittance below ~210 nm. Note: Coatings can be applied to Acton standard substrates, custom substrates, and customer-supplied material (CSM). Contact us at [email protected] for more details.
