Replicated gratings for use in transmission are
available from Optometrics Corp. in a variety of standard and custom sizes. With
thickness and dimensional tolerances of ±0.5 mm, the blazed devices were designed
for optimal performance in the visible spectrum, offering various levels of dispersion.
The company says that the efficiency of the gratings usually is comparable to that
of the reflection types used in the same region of the spectrum. Available with
or without broadband antireflection coating on the back surface, the devices are
suitable for fixed grating applications, such as spectrographs.
