Fixed focus large beam collimatorator
The air gap glued lens can provide better beam quality than aspherical lens and achromatic lens. The design of low phase difference lens group can obtain more close to Gaussian beam, smaller divergence angle and smaller wavefront error.

Multiple working wavelengths available
It can be used for collimation transmission and also for coupling reception
Light beam divergence angle (full angle) ＜ 0.02 °
Each lens is coated with an antireflective film to minimize surface reflection
Standard FC/APC, FC/PC, Sma905 connectors
