Description
Fiber optic collimator is used to make divergent light into parallel beam or coupler the parallel beam into the fiber.
We supply single mode and multimode fiber collimator with different diameters.Typical fiber collimator wavelength is 1310nm and 1550nm.Lens diameter is 1.8mm or 1.0mm. fiber length is 1.0mm or 1.5mm.Fiber collimator could be with SC FC ST connectors etc.
Fiber collimator features:
– Low insertion loss
– Low back reflection
– High environmental stability
Fiber optic collimator applications include laser beam delivery systems, coupling the output of a fiber into a detector. Applications of pairs of collimators include beam expansion systems for lab applications, as well as fiber-to-fiber coupling in compact components.

I have purchased a couple of these collimators, and they work really well. Not worse than a device from a well-known brand, that I used in our lab, but the price is about ten times lower. And shipping was fast enough as well.
