The 780/830/850nm C-Lens Fiber Collimator with Gold-Plated Tube/Glass Tube is a high-precision optical device designed for collimating light from optical fibers with minimal divergence. Operating at 780nm, 830nm, and 850nm wavelengths, it ensures low insertion loss, high return loss, and superior beam quality, making it ideal for fiber optic communication, laser systems, biomedical applications, and optical sensing. The gold-plated tube enhances durability and heat dissipation for high-power applications, while the glass tube offers excellent optical stability and reliability. Engineered for stable and efficient light transmission, this collimator optimizes coupling efficiency and reduces beam divergence, making it a preferred choice for scientific research, optical testing, and industrial laser applications. Custom configurations, including fiber type, working distance, and housing material, are available to meet specific requirements.
