Materion Corporation UV Steep Edge Filters

Barr Custom Steep Edge Filters are designed for laser applications where deep attenuation of laser radiation is required with sharp cut-on slope so as to afford high transmission very close to the laser line. Filters of this type are typically used in Raman Spectroscopy where the Rayleigh line must be effectively suppressed while transmitting Raman scattering separated as closely as 100 cm-1 from it. Barr Steep Edge Filters can be designed for use in the UV, Visible, and NIR spectral regions and are manufactured with refractory oxide coatings which show robust environmental durability characteristics.
