Features

• All fused silica design
• Clean Gaussian beam at any distance
• No epoxy in optical path
• Adjustable focus

Our FC5FS fiber collimator is designed for long distance transmission of high power fiber lasers. An all fused silica design minimizes thermal problems associated with most other types of collimators. It is designed for use with singlemode and polarization maintaining fibers.

Output collimation is adjustable so that you can tune to the exact wavelength of use. Output beam is very well corrected to give a diffraction limited beam with low wavefront error. There is no epoxy in the optcal path. Standard FC and FC/APC receptacles are used on the input.

Accessories include adapter designed to mount the fiber collimator onto common optical mounts.

The FC5FS collimator is ideal for free space communications, lidar, remote sensing, interferometry, confocal microscopy and other applications requiring excellent beam quallity and low scatter.
