Infrared Diffraction Gratings

These Infrared Gratings are original rulings or replicas that are typically used for tuning high and low power infrared lasers and wavelength scanning and selection in broadband infrared spectroscopy applications.

The product listing offered below includes the standard replicated version of our Infrared Diffraction Gratings. For high power applications, these same gratings, as well as custom optimized designs, may be supplied as original rulings ruled directly into the metal substrate surface.

We can manufacture these gratings as original gratings ruled directly into an aluminum coating deposited on a kanigen coated copper substrate. This gives the original gratings an inherently higher damage threshold than their replicated grating counterparts which are produced on a Pyrex^® substrate.

For more information or to order an original ruled grating, please email or call us at 978-772-1700.
