Produced by Omega Optical Inc., and distributed by LASER COMPONENTS throughout Europe, the filters are successfully designed, creating over 70% transmission at 350nm with a 10nm wide band. Owing to this new technology and proprietary material selection, these filters provide higher transmissions, steeper edges and deeper blocking than previously seen. Moreover, as ZrO2 maintains a refractive index of 2.2 throughout the visible range, blocking without the use of metals can be achieved up to 700nm.
Additionally, by including a new UV gain flattening filter, extended blocking up to the FIR range can be achieved whilst still providing a transmission as high as 40%.
