Where LMMJ7051A is specified

An M12 ultra-wide board lens for corridors, counters, and compact modules that need coverage without a 190°+ fisheye. Typical stations below.

Corridor, counter, and door modules

150° is the catalog choice when you need more than a normal board lens but do not want a 190° fisheye. Horizontal FOV is 115°.

Robotics guidance in compact housings

2.85 mm F2.5 on 1/2.9". BFL 5.75 mm and CRA 17° are the sheet values to check against the sensor stack.

Security and people counting

5MP M12 coverage in a compact barrel. 5MP on 1/2.9"; image circle Φ6.5. Match the circle to the sensor diagonal before you freeze the FOV.

1/2.9" M12 board cameras

Specified for this sensor class on M12×0.5P. Send the camera or Sony IMX part number and we confirm image circle and CRA against LMMJ7051A.

How to specify this lens

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

Camera or sensor PN

Sony IMX or the board-camera model. We confirm 1/2.9" format, image circle Φ6.5, CRA 17°, and M12 thread against LMMJ7051A.

Target FOV and housing

The field you must cover and any TTL / cap-diameter limit. If 150° is wide or tight, we shortlist 144° or 151° from the same M12 line.

Sample qty and annual volume

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

What you need back

Datasheet, 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 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 LMMJ7051A

What is the LMMJ7051A wide angle lens?

LMMJ7051A is a 2.85 mm F2.5 M12 wide-angle / fisheye lens for 1/2.9" 5MP sensors. Official FOV is 150° / 115° / 73° (D / H / V). It is a catalog part in the Lensmind LMMJ M12 wide-angle series.

What cameras and sensors does it fit?

It is specified for 1/2.9" sensors on M12×0.5P. Image circle Φ6.5, CRA 17°, BFL 5.75 mm. Send the camera or sensor part number and we confirm fit against this model or a nearby FOV.

What FOV, EFL, and TTL should I plan for?

On a 1/2.9" sensor the field of view is 150° / 115° / 73° (D / H / V). EFL is 2.85 mm. TTL is 17.5 mm; front cap Φ14. These are sheet values, not series estimates.

Is this a pericentric 360° inspection lens?

No. LMMJ7051A is a refractive M12 fisheye / ultra-wide board lens. Pericentric and catadioptric side-wall inspection optics are engineered to order on the 360 panoramic line. Use this SKU for scene coverage; use a pericentric build to measure a cylinder circumference.

Can you customize FOV, F/#, or mount?

Yes. 2.85 mm F2.5 M12 with 150° is the catalog starting point. Custom FOV, 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 and mechanical drawing?

Yes. Open the inquiry form with the model, sensor, and quantity. The reply includes the datasheet. Mechanical drawings go out at quotation stage.

What is the sampling MOQ?

Catalog wide-angle 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 144°, 150°, or 151°?

LMMJ7034C is 3.08 mm, FOV 144° / 119° / 63°, TTL 14.76 mm. LMMJ7051A (this page) is 2.85 mm, FOV 150° / 115° / 73°, TTL 17.5 mm. LMMJ7013D is 2.65 mm, FOV 151° / 115° / 75°, TTL 18.9 mm. Match FOV to the scene, or send both FOV and housing and we shortlist.
