Diagonal field of view reaches 178.0° on 1/1.8-inch IMX678, capturing panoramic and ceiling-mounted scenes in a single frame.
F/1.60 aperture transmits more light than slower fisheye designs, holding detail in dim corridors and night-lit streets without longer exposure.
The IP67-rated barrel seals the optical stack against dust and water jets, suiting outdoor housings, robots, and inspection equipment.

The ø9.20 mm image circle covers 1/1.8-inch formats, and the model is characterized on the Sony IMX678, the 1/1.8-inch SmartSens SC4210, the 1/2-inch IMX385, and the 1/2.3-inch IMX577. Send your sensor model and pixel size and we confirm field of view and chief ray angle match before you build the holder.
Distortion is quoted on a θ-g basis: under −4.09% on IMX678, −4.31% on SC4210, −2.32% on IMX385, and −1.31% on IMX577. Fisheye mapping still needs de-warping in the host pipeline, but a controlled baseline keeps calibration and stitching stable across production units.
IP67 is declared for the lens barrel construction against dust ingress and water jets. Final protection depends on your holder, gasket, and focus-locking method, so validate the assembled module against your own ingress test instead of relying on the lens rating alone.
Evaluation samples can be arranged through the sales channel for bench testing. Share the sensor model, holder drawing, and target working distance, and we confirm that BFL 4.35 mm, the 5.00 mm rear step, and the diagonal field of view fit your module before tooling or volume planning.
The 2.96 mm focal length is fixed for this model, so a different EFL requires a new optical design. IR-cut wavelength and coating variants can be reviewed as custom configurations once your sensor, spectral target, and mechanical envelope are defined.
No. The filter holds transmission at or below 3% from 700 to 1000 nm and below 5% at 1050 nm, so the lens is configured for visible-light imaging with corrected color. Near-infrared work needs a different filter configuration, handled as a separate custom item.
We don't just sell lenses. We run a full optical verification cycle — on your sensor, under your constraints — before we recommend anything.

The JSD2916-J1 is a 2.96 mm M12 (S-Mount) fisheye lens for 8MP camera modules on 1/1.8-inch sensors such as the Sony IMX678 and SmartSens SC4210. Its ø9.20 mm image circle delivers a 178.0° diagonal field of view on IMX678, so one camera covers a full room, aisle, or cabin instead of several narrow-angle modules. Panoramic security, robot and AGV vision, UAV capture, and embedded vision devices use it to cut module count and mounting volume.
The 5G3P stack pairs five glass and three plastic elements with a built-in IR650 filter: average transmission is at least 90% from 440 to 620 nm, 50% at 650 ± 10 nm, and no more than 3% from 700 to 1000 nm, so daylight color is corrected inside the barrel. At F/1.60, relative illumination stays above 54.90%, and θ-g distortion remains under −4.09%, giving de-warping pipelines a controlled starting point.
The barrel is M12.00×P0.50 with TTL 27.50 ± 0.3 mm, ø26.00 mm maximum outer diameter, a 5.00 mm rear step, BFL 4.35 ± 0.2 mm and FBL 3.55 ± 0.2 mm. The IP67 rating covers the assembled barrel against dust and water jets; final ingress protection depends on the holder seal in your module. Chief ray angle stays under 19.17°. Drawings, samples, and custom IR-cut or coating variants can be reviewed against your sensor and housing.
