Photonwares’ High Power Fiber Collimators incorporates advanced technologies of direct fusion to a large beam expanding end cap ensuring safe power density, and a mode stripper that prevents burning the buffer/jacket by removing unwanted back-reflection radiation. These patented technologies significantly increase the collimator reliability. Photonwares provides customized beam size for a wide choice of operating wavelength and fiber types. Due to the mature production operation, we offer the most competitive pricing.
