Options

Fiber coupling - SmartDock
Especially designed for the iBeam smart TOPTICA's SmartDock turns the iBeam smart into a rugged ﬁber coupled diode laser system. Both single-mode and polarization-maintaining fibers can be connected to the SmartDock. Better than 60 % coupling efficiency is guaranteed but efficiencies up to 90 % have been demonstrated due to the high beam quality of the iBeam smart.
Applications
- Raman microscopy
- Raman spectroscopy
- Diffuse Correlation Spectroscopy (DSC)
- Linewidth sensitive applications using acousto-optic-deflector
