PM 850nm In-Line Polarizer

PM 850nm In-Line Polarizer

This PM 850nm In-Line Polarizer delivers high extinction ratio, low insertion loss, and precise polarization control for optical systems operating at 850 nm. Designed with an operating wavelength range of ±20 nm, it ensures reliable slow-axis transmission with effective fast-axis cutoff while maintaining high return loss and minimal polarization sensitivity.

Ideal for communication systems, fiber amplifiers, research applications, and precision sensing, the polarizer supports high power handling up to 10 W and stable performance across a broad temperature range. Its compact packaging and customizable options including fiber type, connector style, and power rating allow for flexible integration into various polarization-maintaining optical systems.
