Azure 2/3\" Ultraviolet (UV) Sensors

The Azure 2/3″ Ultraviolet (UV) Fixed‑Focal Lenses range from Azure Photonics offers C‑mount lenses optimised for UV imaging across a broad spectral window (200–1,000 nm) for 2/3″ sensors. Available focal lengths include 25 mm, 35 mm, 50 mm, and 75 mm with a manual iris range of F2.8–F22. They support typical working distances from ~155 mm to ~200 mm, featuring high-resolution optical performance suitable for 8 MP sensors (~2.74 µm pixel pitch). These lenses lack IR-cut filters and coaxial illumination options, ensuring full UV throughput, and are housed in robust metal barrels to maintain performance across their high-resolution capability.

In practice, these UV‑capable fixed‑focal lenses excel in specialised machine‑vision tasks like plastic sorting, wafer and solar‑cell inspection, authentication marking, UV‑fluorescence detection, and forensic analysis. Their precise manual iris control enables depth‑of‑field tuning and light-level adjustment, critical for high‑contrast UV imaging. The 75 mm version, for example, is ideal for tight field, long‑distance inspections, while the 25 mm lens suits wider scenes at closer distances ~155 mm . OEM technicians or integrators using UV illumination and matched optical filters can accurately capture subtle UV-visible signatures or fluorescent emissions, making these lenses highly suitable for semiconductor fabs, quality control in manufacturing, security document verification, and scientific UV imaging setups.
