SOLAR LS, an expert in the sphere of laser and spectral equipment, has been working in the world photonics market for over 20 years.
Among others, our company carries out development of unique optical schemes and full-scale production of OEM monochromators-spectrographs upon orders of analytical equipment manufacturers.
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.
