Short Pass Filters

Short Pass filters block wavelengths higher than the specified edge wavelength and transmit wavelengths lower than the edge down to a minimum wavelength.

Iridian’s SPFs have a steep edge making them suitable for Raman applications or wherever a very sharp transition between the transmitted and the blocked wavelengths is required. In addition, these SPFs have a low ripple in the passband to meet the demanding specifications of spectroscopy instruments.
