Where LM-M0834AFC is specified

A voltage-driven liquid autofocus lens for 2/3″ machine vision cameras. Typical stations below.

Logistics DWS and barcode reading

Voltage-driven focus on 8.1 mm F3.4 covers parcel height change without a motor. Distortion 3.5% MAX is the ZWA sheet value for this model.

Multi-depth inspection

Refocus between working planes on a 2/3" camera. Mount Φ14, TTL 19.32 mm.

Robotic picking

No VCM wear in the optical path. Send object-height range and we confirm LM-M0834AFC or a nearby ZWA focal length.

2/3" machine vision cameras

Matched to this sensor class at 6 MP. Confirm camera PN and working-distance window against LM-M0834AFC.

How to specify this lens

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

Camera or sensor PN

Sony IMX or the camera model. We confirm 2/3" format and mount Φ14 against LM-M0834AFC.

Working distance and field

Distance from the lens and the height range you need to cover. If 8.1 mm is wide or tight, we shortlist 12 mm or 16 mm from the same ZWA group.

Sample qty and annual volume

Catalog ZWA sampling from a written quantity. Annual quantity sets production slot and price break.

What you need back

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

Built and tested in our own optics factory

Every Lensmind liquid autofocus 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 LM-M0834AFC

What is the LM-M0834AFC liquid lens?

LM-M0834AFC is a 8.1 mm F3.4 electrowetting liquid autofocus lens for 2/3" machine vision cameras. Mount Φ14, distortion 3.5% MAX, resolution 6 MP. Catalog part on the Lensmind ZWA sheet.

What cameras and sensors does it fit?

Specified for 2/3" sensors. Mount is Φ14, TTL 19.32 mm. Send the camera or sensor part number and we confirm image circle and drive interface against this model or a nearby ZWA focal length.

What does distortion 3.5% MAX mean on the line?

Sheet distortion for LM-M0834AFC is 3.5% MAX. That is the official ZWA value for this focal length, not a series estimate.

What FOV and TTL should I plan for?

On a 2/3" sensor the field of view is 69.8° / 56.1° / 47.8° (D / H / V). TTL is 19.32 mm.

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

Yes. 8.1 mm F3.4 Φ14 is the catalog starting point. Custom focal length, aperture, and mount variants are quoted from your sensor drawing.

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 records for this part. Mechanical drawings go out at quotation stage.

What is the sampling MOQ?

Catalog ZWA lenses support sampling from a written quantity. Custom programs start from a drawing or a physical sample, then run prototype-to-mass-production.

Should I use 8.1 mm, 12 mm, or 16 mm?

LM-M0834AFC (this page) is 8.1 mm, F3.4, FOV 69.8° / 56.1° / 47.8°, mount Φ14. LM-M1238AFC is 12 mm, F3.8, FOV 48.5° / 38.1° / 32.2°, mount Φ14. LM-M1643AFC is 16 mm, F4.3, FOV 35.8° / 27.8° / 23.4°, mount Φ14. Match FOV and mount to working distance, or send both and we shortlist.
