Plane Ruled Reflection Gratings

Plane Ruled Reflection Gratings

Product catalog summary

Overview: The document provides technical specifications and ordering information for Newport's plane ruled reflection gratings, which are designed for first order Littrow use. These gratings are blazed for specific wavelengths and are known for their high efficiency at those wavelengths, making them suitable for spectroscopic instrumentation requiring high resolution.

Specifications:

High efficiency at specified wavelengths.
Groove frequencies range from 50 to 2400 grooves per millimeter (g/mm).
Available coatings include aluminum and gold.
Substrate material is float glass.
Available sizes are 12.5 mm, 25 mm, and 50 mm square.

Efficiency Curve: An example efficiency curve is provided for a plane ruled reflection grating with 1200 g/mm, a 17.5° nominal blaze angle, and a 500 nm blaze wavelength with an aluminum coating. The document notes that efficiency curves are relative and can vary based on geometry and measurement technique.

Ordering Information: The document lists various models of gratings with different groove densities, nominal wavelengths, blaze angles, and coatings. Each model is available in three sizes: 12.5 x 12.5 x 6 mm, 25 x 25 x 6 mm, and 50 x 50 x 6 mm. The coatings are specified as either aluminum (Al) or gold (Au), depending on the wavelength and application.

Key Models:

2400 g/mm, 240 nm wavelength, 16.8° blaze angle, aluminum coating.
1800 g/mm, 400 nm wavelength, 21.1° blaze angle, aluminum coating.
1200 g/mm, 1000 nm wavelength, 36.8° blaze angle, gold coating.
600 g/mm, 2700 nm wavelength, 54° blaze angle, gold coating.
150 g/mm, 6000 nm wavelength, 26.7° blaze angle, gold coating.

Additional Information: The document references a diffraction grating mount available on page 695, indicating additional accessories or related products.
