Collimators and Focusers

Product Description: 

Precision Micro-Optics provides a portfolio of fiber collimators and focusers featuring low coupling loss, low back reflection, wide wavelength and beam diameter ranges, and epoxy free for high power handling. These parts are ideal for fiber optical devices, surface detection, as well as other telecommunication and biomedical applications.

For collimators, a rough collimated beam diameter is given by:

                                            Beam Diameter (mm) = 2 x f(mm) x NA

Where f is the lens focal length and NA is the fiber numerical aperture (NA). The beam size here is defined as 1/e2.

For focusers, Measures are taken to reduce the beam spot to the scale of diffraction limit and the wavefront distortion.
