Where LMJJ-FA1617A-8M is specified

A C-mount FA lens for 1/1.8″ cameras on compact AOI and guidance stations. Typical stations below.

AOI / automated optical inspection

Distortion <-0.2% keeps pass/fail geometry usable at the field edge, so the AOI threshold is not eaten by the lens before the part varies.

Robotic guidance and pick-and-place

Fixed 16 mm prescription and C-mount BFL 17.526 mm hold calibration between changeovers. Swap a catalog unit without re-tuning the cell.

Inline quality monitoring

1/1.8" volume stations for presence, polarity, and cosmetic checks. F2.4–16 covers the working aperture on this barrel.

1/1.8" C-mount machine vision cameras

Matched to this sensor class. Send the camera or Sony IMX part number and we confirm image circle and CRA against LMJJ-FA1617A-8M.

How to specify this lens

Send these four items and an engineer replies with datasheet, distortion/MTF records, and pricing within one business day.

Camera or sensor PN

Sony IMX or the camera model. We confirm 1/1.8" format, image circle, CRA, and C vs CS mount against LMJJ-FA1617A-8M.

Working distance and object size

Distance from the lens and the field you need to cover. If 16 mm is wide or tight, we shortlist 12 mm or 25 mm from the same series.

Sample qty and annual volume

Catalog FA sampling from 50 pcs standard MOQ. Annual quantity sets production slot and price break.

What you need back

Datasheet, MTF, mechanical drawing, or a custom F/# / mount. Name it in the message so the first reply is complete.

Built and tested in our own optics factory

Every Lensmind FA lens is machined, coated, cemented, and aligned in-house in Hangzhou. Core optical steps are not outsourced, so a drift found at final test can be traced the same day.

ISO 9001 process control on the production line

1 μm-class active alignment before the barrel is locked

Questions buyers ask about LMJJ-FA1617A-8M

What is the LMJJ-FA1617A-8M FA lens?

LMJJ-FA1617A-8M is a 16 mm F2.4–16 C-mount factory-automation lens for 1/1.8" machine vision cameras. It is a catalog part in the Lensmind HS FA series, used on AOI, robotic guidance, and inline inspection stations.

What cameras and sensors does it fit?

It is specified for 1/1.8" sensors on C-mount. Back focal length is 17.526 mm. Send the camera or sensor part number — Sony IMX and similar — and we confirm image circle, CRA, and mount against this model or a nearby focal length.

What does distortion <-0.2% mean on the line?

Geometric error at the field edge shows up as false rejects or offset picks. LMJJ-FA1617A-8M is held at <-0.2% so the image stays usable into the corners of a 1/1.8" sensor, without relying on software warp as a crutch.

What FOV and focusing range should I plan for?

On a 1/1.8" sensor the field of view is 31.4° / 25.4° / 19.2° (D / H / V). Focusing range is 0.08 m ~ ∞. Filter thread is M27×P0.5 if you need a bandpass or polarizer in front of the lens.

Can you customize focal length, F/#, or mount?

Yes. 16 mm F2.4–16 C-mount is the catalog starting point. Custom focal length, aperture, and mount variants are quoted from your sensor drawing. Feasibility typically comes back with the first reply, within one business day.

Do you send a datasheet, MTF, and mechanical drawing?

Yes. Open the inquiry form with the model, sensor, and quantity. The reply includes the datasheet plus the distortion and MTF records for this part. Mechanical drawings go out at quotation stage.

What is the sampling MOQ?

Catalog FA lenses support sampling from a 50 pcs standard MOQ. Custom programs start from a drawing or a physical sample, then run prototype-to-mass-production. Repeat catalog orders follow the same ISO 9001 release path as the first batch.

Should I use 12 mm, 16 mm, or 25 mm?

LMJJ-FA1217A-8M is 12 mm, FOV 42.1° / 34.2° / 20.1°, focus 0.1 m ~ ∞. LMJJ-FA1617A-8M (this page) is 16 mm, FOV 31.4° / 25.4° / 19.2°, focus 0.08 m ~ ∞. LMJJ-FA2517A-8M is 25 mm, FOV 21.4° / 17.2° / 13°, focus 0.1 m ~ ∞. Match FOV to working distance and object size, or send both and we shortlist.
