The CINEGON series is known for rugged mechanics and stable imaging in production environments. This 10 mm focal length model provides a wide field of view from short working distances and excels in applications such as inspection, measurement, robotics, traffic, and general automation where high throughput and consistent focus are critical. The fast F1.9 aperture supports low-light imaging and short exposures for motion freeze. Key technical details from the manufacturer: 1" format coverage (16 mm image circle) with broadband anti-reflection coating for 400–1000 nm, lockable manual focus and lockable manual iris, C-Mount interface, approximate weight 136 g, and optional front adapter to accept M62×0.75 filters. Typical use cases include 2D/3D metrology and vision systems operating in visible or NIR bands. Order/MPN reference: 21-1001978 (CINEGON 1.9/10). See photos for the exact lens cosmetics including the locking screws and engraved scales. Condition notes: lenses are pre-owned and show light handling marks. Glass presents clear with no obvious haze or fungus seen under normal room inspection; minor dust typical of use may be present and does not affect performance in most setups. Mechanical controls feel correct with smooth travel and functional locks. No accessories, caps, or mounts beyond what is pictured are included. No testing beyond visual inspection has been performed; calibration and alignment are the responsibility of the integrator. Ships from Carol Stream, IL, USA with careful packaging. Integration tips: Pair with 1" global-shutter cameras for maximum field utilization; for smaller sensors, cropping will effectively increase angle of view equivalence. Use the focus and iris locks to hard-set depth of field for stable measurements. For NIR work, the 400–1000 nm coating helps maintain contrast on 850–940 nm illumination. Filter threads accept common M62 polarizers or bandpass filters via the front adapter.
