Is M12 the same as S-mount?

Yes. S-mount is the mount standard's name; M12x0.5 (12 mm barrel diameter, 0.5 mm thread pitch) is its physical thread. Every lens on this page follows the M12x0.5 S-mount standard, so an S-mount camera body and an M12 lens are mechanically compatible.

Is an S-mount lens the same as a Canon EF-S lens?

No. In machine vision, S-mount refers to the M12x0.5 thread standard used on board-level and embedded cameras. Canon EF-S is a DSLR bayonet mount for APS-C cameras and is completely unrelated. All S-mount references on this page mean the M12x0.5 industrial standard.

Which sensors do the H-series lenses cover?

The H-series (H05-H30) is built for 1/1.8-inch-class sensor targets. The M-series covers larger formats, and the T-series handles special optical requirements. Send your sensor part number and we confirm coverage and chief ray angle compatibility.

How do I read the aperture suffixes in the part number?

The two-digit suffix encodes the fixed aperture stop: 11 = F11, 40 = F4.0, 56 = F5.6, 70 = F7.0, 80 = F8.0. Each focal length is offered across these five fixed stops, so the aperture you calibrate is the aperture you keep.

Will these lenses hold focus on a vibrating robot arm?

Specify the FT (full-thread) versions. Full-length thread engagement locks the optical prescription against high-frequency vibration, which is the exact failure mode that works standard partial-thread mounts loose on robot arm ends, AGVs, and mobile platforms.

What is the difference between FT and HT?

FT is the full-thread focus lock: the barrel threads engage the mount along its full length for maximum vibration resistance, at the cost of a slightly longer barrel. HT is the half-thread mount: a shorter, more compact build for stable enclosures and benchtop units where vibration is not the dominant load.

Can I order one optical design in both NIR and VIS configurations?

Yes. Each M12 optical design is ordered in a VIS (visible) or NIR (near-infrared) configuration matched to your illumination plan, from strobed visible light on a production line to IR flood that ignores ambient glare. The spectrum is specified in the order code; the mechanical and electrical interface stays identical.

Where can I find M12 lens dimensions?

Per-model datasheets include mechanical drawings: optical length, thread engagement, and flange distance. Request the dimension set for your shortlisted focal lengths via the datasheet CTA and it arrives with the model list.

Do you offer M12 macro lenses?

Close-working-distance requirements are handled within the series and the T-specials. Tell us the working distance and the feature size you need to resolve, and we route you to the closest catalog option or a quoted custom variant rather than guessing.

Do you offer M12 fisheye lenses?

True fisheye fields of view are better served by our 360-degree panoramic optics or a custom design. If your requirement is a wide but rectilinear field, an H-series short focal length may already do the job; send the target field of view and we route it honestly.

Why fixed apertures instead of an adjustable iris?

An iris is a moving part. Five fixed stops per focal length remove the drift, rattle, and wear of adjustable mechanisms, so light transmission and depth of field stay exactly as calibrated across the fleet and across production batches.

What about batch consistency, sampling, and lead time?

Catalog M12 lenses run under the same 10K+ batch-consistency discipline as our FA lines, with 1-micron-class active alignment and per-batch records. Catalog sampling is low-MOQ; custom variants run 60 working days prototype-to-mass-production and 30 days on repeat orders.
