High-Precision Knob-Focused Collimator
The high-precision knob-focus collimator collimates fiber output or couples free-space light into fiber. Controlled machining tolerances and a special internal design maintain excellent coaxiality throughout focus adjustment. Fine threads balance smooth operation with precision. Long-term stability is good, with little internal stress from ambient temperature changes and sustained high coupling efficiency. High-quality lenses ensure Gaussian output and coupling efficiency.
