Pericentric & Catadioptric Specialty Optics

See the Entire Side Wall in One Shot — 360° Panoramic Lenses

Pericentric panoramic optics that image the full 360° side of cylindrical parts — bottle caps, precision threads, machined cylinders — on one camera, one exposure, no rotation stage, no multi-camera stitching. Engineered to order by the Lensmind specialty optics team.

Family / use-case console

Pericentric side-wall optics are project builds. The console is the family; the only catalog SKUs on this page are official 190–220° M12 fisheyes for scene coverage — not invented 360 models.

The 360° Optics We Build, In-House

Shown from the specialty shop: the octagonal mirror assembly and the circular reflector used in catadioptric panoramic configurations. Variant — pericentric top-face or side-wall-only, mirror ring or annulus fold — is set by your part geometry, not picked from a shelf. There is no invented 360 SKU table on this page.

Pericentric, Panoramic, Catadioptric — Which Term Is Which

Peri- + -centric: rays encircle the part. Catadioptric is the means (reflective + refractive fold). Panoramic is the result (full circumference in one shot). We treat them as one family and configure per project.

One Lens, One Camera, the Whole Circumference

The part sits on-axis. Light from every azimuth enters the ring, maps to an annular image, and unwraps to a flat side-wall strip — one deterministic transform, no registration between views. No rotation stage. No multi-camera stitching.

LMMJ7028A 0.9mm F2.0 M12 220 degree wide angle fisheye lens

Pericentric vs. Fisheye: Same Wide Feeling, Completely Different Optical Path

A fisheye images a wide solid angle from one viewpoint in front of the camera. A pericentric lens folds light around the part so the side wall is imaged directly. If you need scene coverage, use official M12 SKUs LMMJ7028A / 7018A / 7058A. If you need to measure a cylinder, stay on this custom path.

Bottle Caps, Threads, Cylindrical Parts — the Side-Wall Map

  • Pharma caps — cracks, tamper rings, print, one audit-ready frame.
  • Threads and fasteners — no part rotation, line keeps tact time.
  • Cans, tubes, battery cells, ampoules, label wrap.

Bore interiors belong on endoscope optics. Pixels/mm is computed from your Ø, height, defect size and sensor — not guessed from a catalog row.

When you need a 190°–220° M12 fisheye — not a pericentric build

MJ7208B / MJ7209A appear in wide-angle application photography; they are not extra rows on the official 14-SKU LMMJ sheet, so this page does not invent those URLs. The panoramic-class catalog models that do exist are the 190° and 220° M12 board lenses below. Use them for scene coverage. For cylindrical side-wall measurement, stay on the custom pericentric path on this page.

360° Inspection Lens FAQ

Questions Integrators Ask Before Going Single-Camera

Can one camera really inspect a full 360 degree side wall?
Yes. A catadioptric panoramic lens folds the full circumference of a cylindrical part into a single annular image on one camera sensor — one exposure, no part rotation, no multi-camera stitching.
What is the difference between a pericentric lens and a panoramic lens?
In machine vision the industry term is pericentric: light rays encircle the part and image the side wall — and on many designs the top face — in one shot. Panoramic and catadioptric describe the same family of fold-the-circumference designs. This page uses both terms because engineers search for both.
How is this different from a fisheye lens?
A fisheye is an ultra-wide-angle refractive lens that images a wide solid angle from a single viewpoint in front of the camera; distortion is the trade for field. A pericentric or catadioptric lens folds light from every azimuth around the part onto the sensor, so the side wall itself is imaged directly. Different optical paths, different measurement geometry.
Is this the same as a security camera fisheye lens?
No. Surveillance fisheye lenses watch a wide area from one viewpoint for scene coverage. Inspection panoramic lenses resolve the circumference of a specific cylindrical part for measurement, with per-batch distortion data and MTF validation. If your machine needs area coverage instead, use an official M12 wide-angle SKU such as LMMJ7028A (220°) or LMMJ7018A (190°) — not a pericentric build.
What resolution do I get on the side wall?
Effective tangential resolution depends on sensor pixels distributed around the annulus and your part diameter; we compute the pixels-per-millimeter figure for your exact geometry during the design review. Typical example data is shared during the design review.
Does the part or the lens need to rotate?
No. The full circumference is captured in a single static exposure; there is no rotating mechanism to maintain and no rotational indexing error.
How does it compare with a multi-camera array on cost?
You buy one lens and one camera instead of N of each, and you remove multi-channel sync, per-camera calibration and per-frame stitching compute from the station. The comparison table breaks down cost, calibration and maintenance line by line.
What part sizes can be covered?
Design scales with part diameter and height, from pharmaceutical caps to larger machined cylinders; send the part drawing for a coverage assessment. Coverage diameter and height ranges are assessed from your part drawing.
What about software and unwrapping?
The annular image unwraps into a flat side-wall strip via one deterministic transform; the mapping is delivered with the lens. Software delivery format is agreed during the design review.
Can it see the top surface as well as the side wall?
Pericentric configurations can image the top face together with the side wall in one shot, depending on the light path designed for your geometry. Confirm top-surface requirements in the project review.
Is a 360 degree optic a catalog product or a custom build?
Most panoramic and pericentric optics are engineered to order around part geometry, defect list and line speed; the fixed path is 60 working days from approved design to mass production and 30 days on repeat orders, under NDA with tooling stored free for 5 years.
Can we test with our own parts before committing?
Yes — send sample parts and we image them with the first-article optic as part of the prototype validation step. Sampling follows our standard policy – sample fees are credited back when your volume order ships.
