Optical Architecture & Beam Performance
Engineered with monolithic aspheric singlets to eliminate spherical aberration completely in both collimation (fiber → space) and coupling (space → fiber) modes.
Ray Tracing: Collimation & Coupling Modes
Fixed-focal-length aspheric singlet reshapes wide-angle divergent fiber output into a collimated parallel beam, or compresses a free-space beam back into the guided single-mode fiber core.

Far-Field Beam Quality (Near Field 0 mm vs Far Field 5 m)
Diffraction-limited Gaussian distribution maintained over distance without high-frequency spatial ripples or diffraction ring degradation (M² ≈ 1).
