Kaiser Optical Systems Inc.'s UltraSpec-C is an enabling component for high-spectral-resolution DWDM devices and analyzers. The Volume Phase Technology holographic transmission grating is recorded in a dichromated gelatin film and sealed between two prisms, providing a beam footprint on the grating that is much larger than the beam cross section. This produces high dispersion and resolution in a 1/2-in.3 package. The component may be combined with off-the-shelf lenses and photodiode arrays to construct optical spectrum analyzers.
