Concave Gratings Rowland Type are preferably used in mountings based on the Rowland circle, (i.e. a circle with a diameter equal to the radius of curvature of the grating). If the entrance slit is located on the Rowland circle, then the spectral focus will also be on this circle.

Product Description
Diffraction Gratings are optical components used to separate light into its component wavelengths, usaully used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings contain a series of closely packed grooves that have been engraved or etched into the Grating’s surface. Diffraction Gratings can be either transmissive or reflective.
