Hard-Coated Broadband Filters

Hard-Coated Broadband Filters

Hard-Coated Broadband Filters are advanced optical components that utilize magnetron sputtered, hard-oxide coatings on Borosilicate Glass substrates. These first-surface filters deliver exceptional performance with steep transitions from high peak transmission to OD4 blocking, without using absorbing filter glasses. Optimized for standard Raman wavelengths (488, 514, 532, 633, 785nm) and available in three standard sizes, these filters combine durability with precision for demanding applications requiring high-temperature operation.
