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
