The e²® - PCGs from Jenoptik are the right solution to enhance your laser performances. Besides high diffraction efficiency, low wavefront error, high laser induced damage threshold, the e²®- PCGs are protected against external mechanical damages and dusty due to the fact that the grating structure itself is embedded.

The Jenoptik PCGs are custom designed and fabricated into high-purity fused silica guaranteeing high laser damage threshold and thermal stability.

Echelle grating

Jenoptik offers high-quality optical components for precise measurement, analysis, structuring and processing using light.

Blazed gratings are optical gratings, which are design in such a way to optimize diffraction efficiency for a specific diffraction order. Although blaze gratings are typically designed for single wavelengths and small diffraction angles, Jenoptik´s blazed gratings can also work at larger angles.

Diffraction grating formula

Like other optical gratings, blazed gratings are periodic in design, which determines to final diffraction angle. The profile of the blazed grating is a triangular cross section, often called a  sawtooth-shaped cross section. Jenoptik can fabricate blazed gratings with very tight control on the period and the angle of the saw tooth cross section, which results in a high diffraction efficiency in the desired diffraction order.
