Features
Micro focus optics used for focussing the collimated radiation exiting a fiber collimator.
Description
The Micro Focus Optics type 25M-M300-26 is used to generate a small laser spot from the collimated radiation of a fiber collimator.
The size of the spot and its Rayleigh range is determined by the fiber properties and by the focal lengths of the fiber collimator and of the micro focus optics. For single-mode fibers the Gaussian intensity distribution and beam shape are maintained.
It is designed for the fiber collimators series 60FC-L or 60FC-T with an outer diameter Ø 32 mm.
Adjustment:
In order to change the working distance of the Micro Focus Optics the lens position of the adjacent collimator has to be readjusted.
Housing material:
As standard, the housing of the Micro Focus Optics is made of nickel silver.
For amagnetic fiber collimators Schäfter+Kirchhoff offers Micro Focus Optics with housings made of titanium.
