Fixed Focus Large Beam Collimator 1550nm

Fixed Focus Large Beam Collimator 1550nm

Using air-gap cemented lenses, it can provide superior collimation performance compared to aspherical lenses and achromatic lenses. The low aberration lens group design achieves a beam closer to a Gaussian beam, with a smaller divergence angle and reduced wavefront error.

Product features：Multiple working wavelengths available、 Can be used for collimated emission or coupled reception、 Beam divergence angle (full angle) < 0.02°、 All lenses are coated with anti-reflection coating to minimize surface reflection、 Standard FC/APC, FC/PC, SMA connectors
