Solution for mounting order sorting filters on a monochromator

The AB202 was basically designed to install an order sorting filter that is needed to use with a monochromator. But also it can be used with any SP's instrument depending on the requirements.

It can hold two filters with different thicknesses. The filter chamber has enough space so fast and easy filter changing is possible.

The AB202 can accommodate a lens matching the F# of a monochromator to collimate the output lights or focusing collimated input light onto a detector.
