830 Grooves, 25mm Square, 800nm NIR Ruled Grating

Product Details Increased Reflection from 700 – 1100nm Near-IR (NIR) Reflective Gold Gratings are ruled gold-coated versions of our commercial gratings. These gratings provide increased reflection from 700 – 1100nm. This makes them an excellent choice for applications such as fiber optic pulse compression and spectroscopy setups using silicon detectors . Near-IR (NIR) Reflective Gold Gratings feature a float glass substrate and a ruled grating construction. The gratings are available in three sizes, with varying groove densities and blaze wavelengths. Handling Gratings: Gratings require special handling, making them prone to fingerprints and aerosols. Gratings should only be handled by the edges. Before attempting to clean a grating, please contact us.
