Monochromator-F

Monochromator for fiber-coupled light sources

Any fiber-coupled light source can be attached to this compact, software-controlled fiber-to-fiber monochromator, e.g. an LED or laser-pumped plasma light source can be connected. The high light throughput results in a flexible, tunable point light source with high luminance at the output fiber.

Quick and easy change of gratings

Thanks to a magnetic-kinematic holder, the optical grating can easily be changed by the user. A number of gratings are available, optimized for the UV, VIS or NIR / MIR wavelength range, which can be exchanged in just a few steps thanks to a factory pre-adjustment. Depending on the fiber core diameter, bandwidth between 0.8 and 28 nm are possible.

Motorized filter wheel and shutter

A motorized filter wheel for up to 5 order sorting filters and a motorized shutter are integrated. Op-tionally, the Monochromator-F can be equipped with a high-speed shutter, which allows reproducible switching times of down to 10 ms.

Control and software

The wavelength is selected from a PC or laptop via a USB interface. Easy-to-use software is included. External control and integration into your overall system are possible via LabVIEW, Python, etc. as well as via direct ASCII commands.
