MonoRa150i

MonoRa150i is a150 mm, f/4.3 aperture, dual grating monochromator and imaging grade performance by two
aspheric mirrors featuring built-in computer compatibility and a scanning range.
It offers 0.2 nm resolution with 1200gr/mm grating, plus easy integration into automated spectral data acquisition systems, named Monoworks. MonoRa150i is ideal for both emission and excitation.
