Long Edge

Long Pass filters block wavelengths lower than the specified edge wavelength and transmit wavelengths higher than the edge up to a maximum wavelength.

Iridian’s LPFs have a very 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 LPFs have a low ripple in the passband to meet the demanding specifications of spectroscopy instruments.
