SD Filter wheel

The SD six-position filter wheel holds up to six 16mm diameter filters and due to the interchangeability nature, many filters can be installed to cover a wide spectral range.

See specifications tab for example filter curves.


The SD is available with either manual or motorised filter selection. In motorised format a stepping motor drives the compact filter wheel via the monochromator/spectrograph controller. The SD filter wheel is fully compatible with the Omni-λ series monochromators/spectrographs.
