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.

Dispersive elements in Rowland circle spectrometers

Rowland gratings are concave gratings designed for the illumination of a Rowland circle. Thus concave diffraction gratings possess both dispersing and imaging properties.

The basic form of imaging gratings is the Rowland circular grating. ZEISS concave gratings are always holographically manufactured and the radii can be selected over a wide range. This means that aperture ratios of up to 1:1 can be achieved. Rowland circle gratings combine imaging properties with UV and VUV spectral range applications to enable the lowest resolution and best signal-to-noise-ratio. ZEISS supports you with customized gratings tailored to your application.
