780nm pigtail GRIN fiber collimator
The pigtail GRIN fiber collimator is formed by accurately positioning the tail fiber and lens, which can convert the transmitted light inside the fiber into collimated light or couple external parallel light into the fiber; We can customize products with different wavelengths and powers according to customer needs. We can also provide high-power (100 watt level) air-cooled versions, which can be applied in fields such as fiber lasers, LiDAR, infrared sensing, scientific research, etc.
