• Excellent Diffraction Efficiency
• Wavelength Options from Ultraviolet to Infrared
• Ruled and Holographic Designs Available
Richardson Gratings™ High Precision Reflective Diffraction Gratings are precisely manufactured for consistent,
predictable performance. Holographic designs, optimized for reducing stray light, are recorded in a photoresist
by exposure to an intense laser interference pattern and chemically developed to reveal a sinusoidal cross
section. Holographic gratings are particularly well suited for stray light sensitive applications such as Raman
spectroscopy.
Richardson Gratings High Precision Ruled Reflective Gratings, with aluminium and gold coatings, are manufactured
from highly accurate masters to provide consistent performance for OEM system integration. These
ruled gratings are characterized by their superior efficiency at their design wavelength. The aluminium coated
versions are designed for demanding applications such as high-resolution spectroscopy, and the gold coated
versions are designed for use in the infrared and are an excellent choice for telecommunications or applications
using InGaAs detectors. Note: The groove structure is very sensitive to damage and should never be touched.
Dust can be removed using filtered air if needed. Custom sizes are available on request.
• Highest Resolving Power and Dispersion
• Low Groove Density for Use in Higher Orders
• Groove Spacing Tolerance <0,05%
Richardson Gratings™ Echelle Reflective Diffraction Gratings feature superior resolving power and dispersion
compared to other reflective diffraction gratings. These gratings are characterized by coarse groove spacings,
relatively low groove densities and high blaze angles. They are suitable for use from near-UV wavelengths to
the infrared (~20μm). Richardson Gratings™ Echelle Reflective Diffraction Gratings are ideal for applications
such as compact high resolution spectrometers with high angular dispersion and throughput. Custom sizes are
available on request. Note: The surface of these gratings is very sensitive and should never be touched when
handling the optic. If cleaning is required to remove dust particles, non-contact cleaning using clean compressed
air is recommended.
