LightSmyth diffraction gratings – quietest on the market.
Recent detailed measurement of light scatter concludes unambiguously that LightSmyth diffraction gratings outperform traditional holographic and ruled gratings by providing up to two orders of magnitude lower levels of scattered light at competitive diffraction efficiencies. For technical details please see the following application note.

LightSmyth Announces 7200 line/mm Silicon Gratings
LightSmyth Technologies has introduced the latest addition to its line of nano-structured silicon grating products. The new silicon grating offers an unprecedented groove density of 7200 lines/mm (140 nm period), making it the only commercially available product with such a fine feature size.
The surface corrugated silicon grating comes in standard sizes of 12.5 x 12.5, 25 x 25 mm and 50 x 50 mm and custom sizes up to 300 mm in diameter. Three groove depths are available, 45, 55 and 65 nm. The substrate is single-crystal silicon with the thickness of 0.78 mm. The grating profile is trapezoidal with sidewall angle of about 83 degrees.
Nano-structured silicon gratings have a variety of applications in optical science (diffraction gratings), for chemical and biological experimentation, polymer testing and high efficiency solar cells.
