These reflective collimators are based on a 90° off-axis parabolic mirror, which has a focal length that remains constant over a broad wavelength range. They are available with either a UV-enhanced aluminum coating, for high reflectivity in the 250 nm to 450 nm wavelength range, or a protected silver coating, for high reflectivity in the 450 nm to 20 µm wavelength range. Compact reflective collimators with a protective silver coating are available for easy integration into cage systems. Protected silver-coated, adjustable-focus reflective collimators allow fine-tuning of the fiber-to-mirror distance. All reflective collimator options are available with FC/PC, FC/APC, or SMA connectors.
