Maximise your sensitivity and scan speed with our patented HD gratings. Achieving the clearest, deepest SD-OCT images requires broad bandwidth and maximum signal-to-noise ratio, so our HD gratings are engineered for high efficiency across all polarizations — even over wide 100–200 nm wavelength ranges.
Select from our stock options or leverage our OCT expertise to design your ideal grating. OEM partners rely on us from concept through product launch, with support for volumes ranging from tens to thousands. Wasatch Photonics can customize transmissive VPH gratings to meet your exact size, wavelength, and dispersion requirements.
