Specifying Surface Figure And Wavefront Distortion For Multi-layer Optical Filters
Specifying Surface Figure And Wavefront Distortion For Multi-layer Optical Filters Optical filters are used in many applications and the surface figure and wavefront distortion requirements of filters are dependent on where and how they are used. If filters are only used in sensing applications with very tolerant detector geometries, there may be no need, in practice, to put any constraints on the surface figure or wavefront distortion. This white paper helps the reader understand where, when, how, and how much to specify...  Continue Reading...

  • Raman Filters
    Raman Filters

    In Raman spectroscopy applications, emitted light is very close in wavelength range to the excitation light. In order to attenuate a laser’s signal from reaching the detector while at the same time transmitting the weak emitted light signal, notch or edge pass Raman filters are required. Because of their high transmittance and extended deep blocking, Raman laser line filters are also required to ensure that only the desired wavelength is actually illuminating the sample being tested. This page provides an overview of Iridian Spectral Technologies' line of filters for Raman spectroscopy.
