Air-spaced doublet collimator FC520-6.1-PC

The air-spaced doublet collimators provided by LBTEK have no moving parts, featuring a compact structure unaffected by misalignment, which simplifies the coupling of free-space lasers to optical fibers. The air-spaced doublet collimators with FC/PC connectors are currently available in ten design wavelengths: 405 nm, 450 nm, 520 nm, 635 nm, 780 nm, 850 nm, 980 nm, 1064 nm, 1310 nm, and 1550 nm. They are coated with anti-reflection coatings to reduce reflectivity. For detailed parameters, please refer to the parameter table. LBTEK offers various customization services. For specific customization requirements, please contact LBTEK Technical Support.
