THE MODULAR OEM-SPECTROGRAPH model S202
The modular S202 OEM-spectrograph is an attractive alternative to a scanning monochromator for atomic emission spectroscopy with spark, arc, laser and inductively coupled plasma excitation.
Our patented double-dispersive optical scheme provides high spectral resolution within a compact design, as well as high aperture and low stray light.
Rigid housing having no moving parts ensures high mechanical and thermal stability. The most popular 1200 lines/mm diffraction grating provides the multichannel array bandpass of 40nm with average dispersion 1.5nm/mm.
ADVANTAGES:
High spectral resolution in a compact design
No moving elements
Rigidness and thermal stability
Modular design
Low stray light
