Which 12 mm M12 variant?

Same EFL family on the Lensmind ZW M12 sheet. Neighbours differ by F/# or IR-cut — not by a guessed field of view.

Where LMZW-M1256M12FT is specified

A 12 mm M12 lens for 1/1.8″ H-series or 2/3″ M-series board cameras on fixed-distance identification stations. Typical stations below.

Board-level and S-mount cameras

M12×0.5 is the S-mount thread. Send the sensor part number and we confirm 2/3" coverage against LMZW-M1256M12FT.

Robot arms, AGVs, and mobile units

FT full-thread engagement is the catalog lock for high-frequency vibration on robot arms and AGVs. Sheet distortion is -0.01%.

Embedded inspection and code reading

Fixed 12 mm F5.6 with MOD 100 mm. No adjustable iris to drift between the sample and the production lot.

VIS or NIR illumination

This configuration has no IR-cut filter, so it is the NIR / no-filter option on the sheet. The mechanical interface stays M12×0.5.

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

Board camera or Sony IMX part number. We confirm 2/3" format, CRA, and M12×0.5 thread against LMZW-M1256M12FT.

Working distance and object size

Distance from the lens and the field you need to cover. If 12 mm F5.6 is wide, tight, or the wrong spectrum, we shortlist F3.8 or F3.8 VIS from the same EFL family.

Sample qty and annual volume

Catalog M12 sampling is low-MOQ. Annual quantity sets production slot and price break.

What you need back

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

Built and tested in our own optics factory

Every Lensmind M12 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 LMZW-M1256M12FT

What is the LMZW-M1256M12FT M12 lens?

LMZW-M1256M12FT is a 12 mm F5.6 M12×0.5 S-mount lens for 2/3" board cameras. It is a catalog part in the Lensmind ZW M12 series (Full thread, No IR-cut).

What cameras and sensors does it fit?

It is specified for 2/3" sensors on M12×0.5. Send the camera or sensor part number and we confirm image circle and CRA against this model or a nearby F/#.

What does distortion -0.01% mean on the line?

Sheet distortion for LMZW-M1256M12FT is -0.01%. That is the official ZW M12 value for this part, not a series estimate.

FT or HT — which thread do I order?

This page is Full thread. FT is full-length thread engagement for vibration. HT is the compact half-thread for stable enclosures.

VIS (IR-cut) or no IR-cut?

LMZW-M1256M12FT has no IR-cut filter on the sheet. Order the VIS sibling when the camera is a visible CMOS under white light.

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

Yes. 12 mm F5.6 M12×0.5 is the catalog starting point. Custom focal length, aperture, and thread 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 M12 lenses support low-MOQ sampling. 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 F3.8, F5.6, or F3.8 VIS?

LMZW-M1238M12FT is 12 mm F3.8, Full thread, No IR-cut. LMZW-M1256M12FT (this page) is 12 mm F5.6, Full thread, No IR-cut. LMZW-M1238M12FT-VIS is 12 mm F3.8, Full thread, IR-cut. Match F/# and IR-cut to light and depth of field, or send both and we shortlist.
