AFC-FC-APC-633
633 nm FC/APC Aspheric Fiber Collimator
The AFC-FC-APC-633 reshapes divergent visible red light from single-mode fibers into a pristine, parallel beam with high wavefront accuracy. Ideal for precision metrology and alignment benches.
Key Advantages
- Crisp Gaussian spot profile at 633 nm with zero spherical distortion
- Dual-surface visible AR coating with >95% throughput
- Stainless steel mechanical construction
