OPT Dolphin 20MP Series Fixed Focal Lenses

OPT Dolphin 20MP Series – Fixed Focal Length Lenses for Industrial Imaging

The OPT Dolphin 20MP series includes high-quality fixed focal length lenses specifically designed for high-resolution industrial imaging and measurement applications. These lenses feature an exceptionally high optical resolution of up to 208 lp/mm across the entire field of view and are compatible with cameras supporting pixel sizes of ≥ 2.4 µm and sensor formats up to 1.1″ (Ø 17.6 mm).

With a broad spectral range from 400 nm to 1000 nm, Dolphin optics are suitable for both visible light (VIS) and near-infrared (NIR). This versatility makes them ideal for various inspection scenarios – from surface and defect inspection to position and feature recognition, as well as OCR tasks (e.g., on PCBs or ICs).

Another advantage is the low distortion and high relative illumination thanks to a chief ray angle (CRA) of less than 5°, which reduces vignetting and ensures uniform brightness distribution across the image field.

The lenses in this series feature manual aperture control and a C-Mount interface, and are available in multiple focal lengths (e.g., 12 mm, 16 mm, 25 mm, 35 mm, and 50 mm) to optimally meet different field-of-view and working distance requirements.
