SPECTROSCOPY
Monochromator & Spectrograph
MonoRa500i
MonoRa500i is a 500 mm, f/6.5 aperture, triple grating Monochromator and imaging spectrograph by two aspheric mirrors featuring a multi-port optical system. It offers 0.045 nm resolution by easy integration into automated spectral data acquisition systems, named Monoworks. Double MonoRa500i is available for twice the dispersion of single monochromator.
MonoRa500i is ideal for Raman, Laser fluorescence, P/L, and emission spectroscopy.
