NIR spectrometer modules for OEM solutions

The innovative transmission grating design of the PSS-M polychromator for NIR spectroscopy guarantees maximum sensitivity and extremely low scattered light levels. The modules are completely adjusted, including wavelength calibration (Δλ < 0.5 nm), and equipped to suit various sensor electronics requirements. The polychromators are therefore particularly suitable as product components for demanding applications.
