The NYLIS spectrometer is the first compact Czerny-Turner array spectrometer offering resolutions down to 0.05 nm (FWHM). Based on the popular ARIS spectrometer, the NYLIS features a larger focal length of 120 nm in a longer housing. This enables better optical imaging as well as smaller wavelength ranges. Both result in spectral resolutions that are unprecedented at this size. It is primarily intended for applications that require high resolution, for example measuring laser radiation. The NYLIS is available in 12 standard wavelength ranges that can be customized for the requirements of individual applications.
