Gratings for UV, VIS & NIR Spectroscopy

We build industry-leading Raman and broadband spectrometers with our gratings, as they are unsurpassed for low light applications and ideal for fluorescence. Our transmissive VPH gratings offer the optical designer many advantages. They are more efficient and much lower scatter than reflective ruled gratings. More robust to handling, they enable transmissive spectral instruments that are smaller in size, lower aberration, and easier to align. At Wasatch Photonics, we apply our multiple patented technologies to optimize for bandwidth, low polarization sensitivity, and/or transmission. Choose from our range of stock gratings, or contact us to discuss your OEM needs.
