Ergonomically designed to facilitate in-field handling/use, PSR+ features optical path configured for improved resolution, SNR, and reliability. System cooling is maximized via one-piece anodized aluminum chassis and integral heat dispersion channels, while Sotex™ filter technology aids order sorting for optimized stray light performance and transition between detectors. Respectively, spectral resolutions include ≤3.0, ≤8.0, and ≤6.0 nm @ 700, 1,500, and 2,100 nm (FWHM).
