The RL-OL series fiber focusing mirror uses two aspherical lens combinations to focus the light beams emitted from the fiber at different magnifications to obtain focused spots with different magnifications relative to the core diameter of the fiber. Each aspherical mirror is coated with a broadband anti-reflection coating: R <1% @ 600-1050nm to minimize the loss caused by surface reflection. The standard product of the optical fiber focusing mirror is the SMA905 optical fiber interface. The meter wavelength is 808nm, which can provide 6 kinds of magnifications. They are compact and easy to integrate into their own devices. The mirror barrel of the focusing lens has external M12X0.5 thread, and it can be compatible with the standard Φ25.4mm optical mount through the mounting adapter. If you have customized requirements for amplification rates, fiber interfaces, or other wavelengths used, please contact us for more information.
