Monochromator & Spectrograph
MonoRa750i
MonoRa750i is a 750 mm, f/9.8 aperture, triple grating Monochromator and imaging spectrograph featuring
a multi-port optical system, built-in computer compatibility, and a scanning range.
As a monochromator, It offers 0.0025 nm drive step size and 0.02nm resolution, plus easy integration into automated spectral data acquisition systems, named Monoworks.
As a spectrograph, it offers 1.0nm /mm dispersion using a 1200gr/mm grating, as well as a 14mm-height x27mm-wide focal plane. Double MonoRa750i is available for twice the dispersion of single monochromator of the same focal length.
MonoRa750i is ideal for Raman, Laser fluorescence, P/L, and emission spectroscopy.
