Home Products Gratings Gratings Applications Spectroscopy
World Leading Raman Grating Supplier
Ideal for when light is precious
As a world-renowned manufacturer of high throughput, low stray light spectrometers, we know what aspects of a gratings performance really matter, namely, high efficiency and low stray light. Our VPH transmission gratings offer both key performance criteria, in a robust, non-replicated, reliable, easy to handle package.
We trust the gratings performance so much, we place them at the heart of all Wasatch Raman spectrometers.
