Optical Collimators

For over 20 years, we have been producing fiber optical collimators according to customer specification using our unique fiber end lens and V-groove technologies. Collimator is an optical system optimized within a working distance range due to cost and size constrains. A practical system is shown in the graph that is characterized by its beam waist size, working distance, and off-axis tilting angle. We have special instruments to precisely measure these parameters. For multimode transmission, the collimator performance intrinsically depends on the laser mode field distribution. To be consistence with customer expectations, a similar profile laser is required during the fabrication and tests.
