Instrument mode can be set for constant spectral resolution (CSR), where the slit width is automatically modified to compensate in the change in dispersion with wavelength to maintain constant spectral bandpass.
Rugged cast construction, A-Thermal design, and SP direct grating drive make this unit the most repeatable and reliable in its class. Each instrument is calibrated and certified prior to delivery.
DK Series Standard Gratings (68 x 68mm)
NOTE: Ruled gratings blazed at different wavelengths and holographic gratings are available on request.
