633 nm FC/PC Aspheric Fiber Collimator

The AFC-FC-PC-633 is a workhorse visible collimator widely used on optical tables for laser beam delivery, optical cage assembly, and positioning measurement.

Wavelength633 nm

Waist (2w₀)~0.64 mm

Divergence (θ)0.032°

Return Loss≥ 45 dB

Key Advantages

Standard FC/PC connector compatibility
Visible AR coating >95%
Precision stainless housing

Contact Optics Specialist

FC/PC Mating Note: Standard 0° flat contact (black/blue boot). Never mate with 8° FC/APC connectors, as the resulting angular wedge creates high loss (>10 dB) and optical damage.

Detailed Technical Specifications

Every Zolix collimator undergoes interferometric wavefront qualification and precision angular alignment before delivery.
