Edmund Optics launches their newly designed TECHSPEC Raman Edge
Filters. These precision filters are ideal for integration into Raman
Spectroscopy, Confocal Microscopy and Life Science Instrumentation.
They provide single filter solutions to reduce spectral noise in Stokes
shift applications. TECHSPEC Raman Edge Filters utilize a hard coated
design for excellent transmission characteristics compared to
traditional coated filters. They are designed to create sharp
transitions between transmitted Raman signals and blocked laser
wavelengths. The filters feature steep edges, which are ideal for
detecting even the smallest Raman shifts.
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.
