Mono- & Polychromator gratings One element – two benefits

Mono- & polychromator gratings combine dispersive and imaging properties in a single element. This reduces stray light, which when combined with image correction, optimizes spectrometer performance and the signal-to-noise ratio (SNL). The blaze profile will be applied during the holography ("True Blaze Technology") and especially for curved substrates the blaze profile is aligned to the surface shape.

See the benefits in the optical properties

With excellent aberration correction, ZEISS Mono- & Polychromator gratings provide enhanced optical performance. Errors such as astigmatism, spherical aberration and coma are minimized in a wide spectral range while the focal surface is optimized. Holographically manufactured, a wide range of standard configurations are available and they can also be tailored to your exact specifications. ZEISS blaze technology enables the blaze profile best suited to the substrate shape during holography.

Improving the image

Image correction during holography can optimize imaging on the detector and minimize errors such as astigmatism, spherical aberration or coma for a wide spectral range in your spectrometer. The spectrum split by the grating can then be projected onto a flat receiver such as a one or two-dimensional CCD sensor in high resolution.

This makes it possible to create compact spectrometers with a minimum of components, which provide high resolution and low stray light at the same time.

Depending on the type of optimization, a distinction is generally made between monochromator and polychromator gratings. Monochromator gratings are optimized for a setup with a fixed entrance and exit slit and a grating that can be rotated around a stationary axis. The focus of a monochromator grating does not shift out of the plane of the exit slit during rotation, which, together with reduced aberration, results in greatly improved resolution.

Polychromator gratings are optimized for setups with a fixed position of entrance slit, grating and planar detection device like CCD, PDA and CMOS.
