Adjustable Focus Laser to Fiber Coupler

Name: Adjustable Focus Laser to Fiber Coupler
Brand: OZ Optics
Availability: InStock

Description

The Adjustable Focus Laser to Fiber Coupler is a high-power optical coupling solution designed for applications where coupling efficiency is crucial, especially in high-power situations. It features a special connector that allows precise control of the spacing between the fiber and lens without rotating the fiber.

This is particularly advantageous for polarization maintaining applications, as it maintains the polarization axis. The adjustable focus capability enables compensation for changes in wavelength or beam wave location, optimizing coupling efficiency and minimizing fiber heating.

Specifications

Coupling Efficiency:	Typically >70% for singlemode and polarization maintaining fibers; >90% for multimode fibers
Backreflection Levels:	<-35dB for multimode fibers; <-40dB for singlemode and polarization maintaining fibers; <-60dB versions are also available
Polarization Extinction Ratios:	>20dB; 25dB and 30dB versions are also available
Available Wavelengths:	200 - 2100 nm
Power Handling:	>5 Watts CW for achromats; >10 Watts CW for aspheric lenses; >100 Watts CW for fused silica or plano-convex and biconvex lenses (multimode fibers); >100 Watts CW for axial GRIN lenses (SM, PM, and LMA fibers)
