High power gratings
Ibsen high power gratings can handle your power/energy
Fused silica transmission gratings from Ibsen offer an order of magnitude higher power handling capability than any other grating technology including conventional Au-coated reflection gratings and VPH gratings.
All our gratings are therefore ideal for high power applications.
