Fused silica transmission gratings offer an order of magnitude higher power handling capability than any other grating technology including conventional Au-coated reflection gratings and VPH gratings.
While specific substrate materials and optional AR coatings may differ, all Ibsen gratings are based on fused silica, with excellent transmission characteristics in all wavelength regions – from below 200 nm to above 2000 nm.
All our gratings are therefore ideal for high power applications, and we furthermore manufacture custom gratings for many different niche applications:
“High power applications” is a broad term; power damage threshold cannot easily be stated in just one or two numbers. Furthermore, to date we do not have information of any power level that has in fact caused damage to our gratings. The table below lists compiled experimental data provided by customers/partners.
Example applications – below damage threshold
