    The Monochromator-F: High throughput from UV to MIR

    Flexible fiber-to-fiber monochromator

    With our Monochromator-F we have developed a versatile device that offers you clean spectral isolation in a wavelength range from 190 nm to 5.5 µm.

    The high-quality fiber-to-fiber coupling of the monochromator allows flexible integration into all systems, while the design of the optical gratings and their mounts enable easy and fast change.

    We look forward to your enquiry.

    Monochromator-F: Compact and easy-to-integrate fiber-to-fiber monochromator

    Thanks to its fiber-to-fiber coupling, the Monochromator-F is compatible with all fiber-coupled light sources, such as LEDs or laser-pumped plasma light sources.

    The reliably high light throughput of the monochromator and the availability of a wide spectrum from DUV to MIR results in a flexibly tunable point light source with high luminance.

    The optical gratings are optimized for the UV, VIS or NIR / MIR wavelength range and, due to their kinematic mounting, can be quickly and easily changed.

    A motorized filter wheel (up to 5 filters) and a motorized shutter are integrated in the Monochromator-F as standard, with the option of complementing this with a high-speed shutter. The desired wavelength is selected using software control via a USB interface.

    • Fiber-to-fiber: Connection and coupling of fiber-coupled light sources
    • Flexibly tunable point light source
    • Easy change of optical gratings
    • Wavelength range from 190 nm to 5.5 µm (DUV to MIR)
    • Bandwidth from 0.7 to 28 nm
    • Very good transmission and little scattered light in the UV range
    • Including Software, control via USB/RS-232, LabVIEW or DLL
    • Optional high-speed shutter with switching times of up to 10 ms

    Integration into Your Software

    Our monochromators can be controlled via a USB interface (RS232). We have developed a Python module that makes integrating our monochromators into your programs very easy.
