- This small curvature grating has dimensions of 15 mm x 15 mm and a focal length of either 25 mm or 35 mm. This grating helps to miniaturize the spectrometer design.
- The gratings are produced with stable quality by precisely replicating from the master gratings with low stray light which are made by holographic exposure method.
- Specifications can be customized according to your requirements.
Example of Optical Mount
Mounting the entrance and exit slits on the Roland circle enables a simple optical system to be built without imaging elements such as concave mirrors.

- * The grating grooves are formed with resin.
- * The external appearances and specifications are subject to change without notice.
- * Nominal blaze wavelength is the wavelength of the maximum diffraction efficiency (target) with the standard optical mounting. No one to guarantee the wavelength of the maximum diffraction efficiency. Blazing is performed with an ion-beam etching technology.
- * Relative efficiency minimum is at the nominal blaze wavelength.
- * The relative efficiency is checked on the optical mount (2 K=35 degrees).
- * Nominal curvature radius is designed one and not guaranteed.
