Single-Mode Fiber Collimator

Single-Mode Fiber Collimator

DETAIL
Single-mode fiber collimator is packaged by precise positioning of fiber pigtail and focusing lens, which can transform the output light of fiber into parallel light beam (Gaussian beam) or couple external parallel light into fiber. It can also be used alone to achieve the required spot size at a specific position according to the predetermined divergence angle.

According to the working distance, it can be divided into fixed working distance (fixed focus) collimator and variable collimator for working distance range. Conventional lenses or Grin lenses should be selected according to different working distances. We recommend installing the collimator in an optical precision adjustment frame for adjustment to ensure the best coupling efficiency.


 

  • Difference between Fixed working distance collimator and Variable collimator for working distance range

Fixed working distance collimator Variable collimator for working distance range
Working distance 1M 0-1M Any position
Beam characteristics Collimation/Focus Collimation
Beam size At a fixed position, a precise sized beam spot can be obtained, with a minimum size of 20um. The beam size rapid changes when moved forwards or backwards. Move forward and backward within an adjustable range, and the spot size changes very little.
Insert loss for a pair Changes significantly with distance Insensitive to changes with distance
Output loss No difference
Return loss No difference
