The DEMON NIR is the perfect choice for quality control and development of lasers in the given range. The popular range around 1.55 µm can be covered with the system and allows an optimization of the spectral purity and investigation of mode behavior of such sources with a resolution in the pm range.
The DEMON-NIR extends the well-established DEMON Echelle Monochromator series providing wavelength ranges from 190 nm to 1100 nm and resolving powers of 75,000 to 200,000.
