AFC-SMA905-VIS

SMA905 Multimode Fiber Collimator (Visible: 400–700 nm)

The AFC-SMA905-VIS is engineered to collimate or collect light from large-core multimode optical fibers (Ø50 µm, Ø100 µm, Ø200 µm, Ø400 µm). Equipped with a threaded SMA905 coupling nut, it provides robust mechanical retention and high optical damage threshold for industrial laser processing, illumination systems, and UV-Vis spectroscopy.

Wavelength550 nm
Waist (2w₀)~2.2 mm
Divergence (θ)0.11°
Return Loss20 ~ 30 dB

Key Advantages

  • Threaded SMA905 connection with high mechanical pull strength
  • Broadband visible AR coating (400–700 nm, >95% transmission)
  • Accommodates large-core fibers from 50 µm to 400 µm
  • High optical damage threshold for pulsed and high-power CW delivery

Detailed Technical Specifications

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