Schäfter + Kirchhoff

We offer fiber couplers like the laser beam couplers series 60SMS or the fiber collimators series 60FC or series 60FC-F with fine-focussing mechanism with achromatic and even apochromatic optics (corrected for 400 – 640 nm).

Coming soon: Double-Pass Acousto-Optic Modulator (AOM) All fiber-coupled, polarization-maintaining acousto-optic modulator setup for tunable frequency shifting and laser light intensity modulation.

The modular muticube™ system of Schäfter+Kirchhoff allows for integration of a variety of acousto-optical modulator setups including various laser wavelengths and RF frequency ranges.

Entire fiber port clusters with integrated modulators can be built. In addition, these setups can be combined with monitor diodes, shutters, beam splitters and other established multicube™ components. More information.

The fiber-coupled laser diode beam sources of type 51nano-S have reduced power noise (< 0.1% RMS (< 1 MHz)), reduced coherence length (≈ 300 µm) and a low speckle contrast as a result of the internal RF modulation. They are available with wavelengths from 405 nm to 1550 nm.

Anamorphic optics act one-dimensionally on the elliptical profile of the collimated beam. They can e.g. be used to adjust the larger beam diameter to the dimension of the smaller one, producing a radially symmetric beam or transform a circular beam into an elliptical one. Anamorphic beam-shaping optics type 5AN are cylinder lens systems and, therefore, can be additionally used to correct the astigmatic difference.

We offer beam delivery systems that consist of a laser beam coupler of series 60SMS, a polarization-maintaining fiber cable and a fiber collimator of series 60FC.
