Flat Field Concave Gratings
Spectrum Scientific's flat field imaging concave grating has grooves that are neither parallel nor equidistant.
This type of concave grating is designed to minimize astigmatism and coma and are suitable for spectrographs or other linear array devices. This makes the aberration corrected concave grating ideal for use with planar array detectors such as photo diode arrays (PDA) or charge coupled device (CCD) detectors.
Spectrum Scientific offers a range of standard gratings. If we do not have a grating that meets your requirement, please contact our sales department as new gratings are manufactured on a regular basis.
