Single Mode Fiber Collimator 405nm Beam Waist Spot 0.70mm

It is composed of a fiber pigtail and a focusing lens that are precisely positioned and packaged. It can convert the outgoing light from the fiber into a parallel beam (Gaussian beam), or focus and couple the external parallel light into the fiber. It can also be used alone to achieve a light spot of the required size at a specific position according to the established divergence angle.

According to the working distance, it can be divided into fixed working distance (fixed focus) collimator and collimator within the working distance range (long depth of field). Spherical lenses or gradient refractive index lenses are selected according to different working distances.

We recommend that the collimator be installed in an optical precision adjustment frame for alignment and debugging to ensure optimal coupling efficiency when coupling spatial beams.

General parameters

Difference	Fixed working distance (fixed focus) collimator	Collimator with adjustable working distance (long depth of field)
Working distance	A fixed position within 1M	Universally applicable within 1M working distance
Beam characteristics	Collimation/convergence/fixed divergence angle	Collimation
Light spot	precise spot size at a fixed position, the minimum size can be 20um, and the spot changes greatly when moving forward and backward	The spot size changes very little when moving back and forth within the adjustable distance range
Pairing loss	The pairing loss changes significantly with distance	Insensitive to changes in pairing loss with distance
Output loss	No difference
Return loss	No difference
