Broadband UV-VIS-NIR SMA905 Collimating Lens

This Broadband Collimating Len is designed to convert divergent light rays from fiber optic cables into parallel beams, ensuring precise and efficient optical alignment. Fabricated from high-quality fused silica, this lens assembly operates across a broad spectral range of 190 – 2100 nm, making it suitable for UV, visible, and near-infrared (UV/Vis/NIR) applications. This accessory is compatible with SMA905 connectors. When connected to a light source, the CLA-SMA produces a parallel (collimated) output beam, which is essential for applications such as light collection, reflectance, absorption, and irradiance calibration (with appropriate setup).  When attached to a spectrometer, the CLA-SMA ensures a narrow acceptance angle and field-of-view, supporting precision measurements under controlled conditions. Key features include: - Focal length: 9 mm - Clear aperture: 6 mm - Effective aperture: 4 mm (with NA 0.22 single core fiber) - Broad spectral compatibility (190 – 2100 nm) - Operating temperature: 0 – 70°C - Non-condensing humidity range: 0 – 85% RH Exceptionally engineered with robust materials, the CLA-SMA is an essential tool for scientists and engineers seeking accurate, repeatable optical measurement setups.
