WP VIS Spectrometer product sheet


We’ve maximized the efficiency of our spectrometers to give you more sensitivity, better SNR, and faster measurements in a compact footprint. Collect more light with our f/1.3 input, keep more light with our patented high transmission VPH gratings & diffraction-limited optics, and detect more light with scientific-grade detectors. When tested side by side, our spectrometers consistently outperform larger, more expensive units. From sample coupling to detector cooling, we give you more options to get the exact performance you need. Call us to discuss your application!
