Guaranteed transition width of less than 1%
TECHSPEC Raman Edge Filters provide guaranteed transition widths of less than 1%. The transition width is the maximum spectral bandwidth between the blocked laser line and the 50% transmission point of the filter. This feature makes angle-tuning unnecessary, greatly simplifying system setup and implementation. The filters deliver high transmission, typically greater than 93%, which allows weak signals to be detected. TECHSPEC Raman Edge Filters are available in 355 nm and 785 nm wavelengths, with diameters of 12.5, 25 and 50 mm. The edge filters are in-stock and available for immediate delivery for fast turnaround and excellent value.
