Diffraction Gratings
Rowland circle gratings Highlighting your spectrometer
Rowland circle gratings for Rowland type spectrometers provide the highest optical quality with excellent resolution, extremely low stray light, good efficiency and accurate groove frequency.
Minimal aberration, maximum application
These gratings are used in mountings based on the Rowland circle, which has a diameter equal to the radius of curvature of the grating. Useful for wide spectral ranges, ZEISS Rowland gratings achieve high resolution with low wavefront aberration and can improve a spectrometer’s signal-to-noise-ratio due to low stray light. Optimized for UV applications, they are easy to use and just work when you need them.
