1064 nm FC/APC Aspheric Fiber Collimator

Designed specifically for the 1064 nm wavelength band, the AFC-FC-APC-1064 provides pristine Gaussian beam collimation for ytterbium-doped fiber laser oscillators, pulsed master oscillators, and seed diode delivery. The monolithic glass aspheric lens contains zero adhesive in the optical clear aperture, ensuring high damage threshold and exceptional thermal stability.

Wavelength1064 nm

Waist (2w₀)~0.78 mm

Divergence (θ)0.05°

Return Loss≥ 60 dB

Key Advantages

High optical damage threshold for pulsed and CW 1064 nm lasers
≥ 60 dB return loss prevents laser cavity destabilization
Monolithic glass element — zero cement in the optical beam path
Factory-stabilized pointing accuracy within ≤ 0.5°

Contact Optics Specialist

FC/APC Connector Note: Uses an 8° angled physical contact interface (green strain-relief boot). Connect only with APC fiber jumpers to ensure ≥60 dB return loss and avoid facet damage.

Detailed Technical Specifications

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