Ibsen is the industry leader in this field, as we are able to make gratings more precisely than anybody else. If you magnify our gratings to the size of a football field, the precision of our grating lines would correspond to a thin blade of grass. Based on these transmission gratings, with the market’s highest efficiency, we offer compact OEM spectrometers. They all have a proven high throughput, verified unit-to-unit repeatability, and provide a flat spectral response. Our decades of experience in delivering transmission gratings have taught us to master the technique to produce gratings for compact and handheld devices.
