Product description:The fiber collimator is an important component of laser devices such as isolators and circulators. It is formed by precisely aligned the optical fiber and the focusing lens. It can not only collimate the beam output from the optical fiber but also couple the collimated beam into the optical fiber. According to the output mode, the collimator can be categorised into two types: non-expanded beam collimator and expanded beam collimator. The non-expanded beam collimator, composed of an optical fiber and a focusing lens, is usually used for beam collimation or coupling in fiber laser systems, has the advantages of simple structure and light weight. Non-expanded beam collimators can be divided into conventional type and direct fusion type. The direct fusion type directly fuses the optical fiber and lens (made of fused silica). Compared with the conventional collimator, it has higher reliability and can withstand higher power laser. The expanded beam collimator is composed of an optical fiber, a focusing lens and a beam expander. The output beam has a small divergence angle and is usually used in a large spot output system. The collimator provided by CASTECH can choose active fiber, passive fiber, polarization-maintai
ning fiber, and non-polarization-mai
ntaining fiber. The wavelength range is 980~2000 nm. It adopts high-quality optical components and a simple and reliable mechanical structure, and has small divergence angle, long working distance, high damage, etc. Various specifications of QCS connectors, special parameter requirements can also be customized according to customers' needs.Applications:-
