Infrared Diffraction Gratings with Optimum Laser Wavelength 3.5μ and Size (mm) 12.5 X 25 mm
Infrared Diffraction Gratings
These 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. 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. Please contact Optometrics for custom infrared diffraction gratings.
Original Ruled Diffraction Gratings
Optometrics manufactures these gratings as original gratings ruled directly deposited on a Kanigen®* coated copper substrate with aluminum coating. This gives the original gratings an inherently higher damage threshold than their replicated counterparts which are produced on a Pyrex® substrate. Contact Optometrics to order custom ruled diffraction grating or call +1-978-772-1700.
