Constant Deviation Monochromator Gratings
A constant deviation monochromator concave grating is used in a scanning monochromator to scan the signal from the entrance slit across the exit slit. Spectrum Scientific’s constant deviation monochromator concave grating removes the need for collimation and focusing optics. This reduces the number of optical elements in the system, increases throughput and allows for a more compact instrument design.
Spectrum Scientific offers a range of standard gratings. If we do not have a grating that meets your specification, please contact our sales team to discuss your specific requirement.
