1.Wavelength: 491nm, 2.Output power: 1-2mW, 3.Fiber connector: FC/SMA905 - details see: https://www.machineto.com/cni-fiber-coupled-laser-system-at-491nm-mbl-491-fc-1-2mw-10231605

491nm Laser Module with Fiber Coupling

All series CNI laser modules can be fiber coupled with different core diameter MM fiber or SM fiber. You have to refer to the detailed specs of each laser modules (such as power, stability, noise, size, etc) to decide which one is suitable for your application. We would like to do the coupling job for you.

Fiber Collimator

These collimators are designed to connect onto the end of an FC/PC or SMA905 connector and contain an AR-coated aspheric lens. The distance between the aspheric lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes or to recollimate the beam at the wavelength and distance of interest.
