Backlit Optical Metrology

Vision-Machine Repeatability for the Counter, Warehouse, and QC Lab

Dedicated laboratory and inline optical inspection machines are built for high-volume factory sorting of small rigid parts, and measuring large flexible seals on them requires specialized stages or multi-camera stitching.

The Olypsys Pro-Vision Booth solves the actual problem maintenance workshops, QC labs, MRO teams, and vulcanizing departments face every day. Controlled diffuse backlighting eliminates ambient shadows and glare, a factory-calibrated Pro Grid locks the geometry across the entire field of view, and our sub-pixel centreline solver measures soft, out-of-round elastomers up to 1,500 mm ID in a single non-contact capture.

Verified Bias & Precision: Standard & Large-Format O-Rings

Large flexible O-rings (400 mm to 1,500 mm ID) are so difficult to measure that external metrology laboratories we approached turned down the work: callipers cannot span them, cones do not exist at that scale, and any contact probe or pi tape deforms the soft cord. In High-Accuracy Large-Format Mode, the Pro-Vision Booth traces a 47-knot spline with photographic edge refinement around the entire ring and computes the true circumference-equivalent ID (centreline length ÷ π − CS).

*Because commercial measurement laboratories declined to certify the flexible 400–1,450 mm rubber O-rings (any contact or manual pi-tape check deforms the cord and is less repeatable than Olypsys), large elastomer rings are evaluated by within-phone SD, back-to-back repeatability, and cross-phone agreement, while certified ground-truth bias is verified on the rigid calibrated steel ring OTCR333-001. See the full Bias & Precision Report.

Why Facilities Choose the Pro-Vision Booth

Controlled Diffuse Backlighting

The enclosed lightbox eliminates overhead glare and oblique shadows, producing a crisp, high-contrast edge profile on black nitrile, shiny Viton, white PTFE, and translucent FEP-encapsulated seals alike.

Accessible Capital Cost

Starting from $3,000 for the 300 mm booth up to $27,000 for the 1,500 mm booth, you can equip your workshop, receiving inspection, and quality control lab for a fraction of the cost of a dedicated laboratory vision machine.

True Perimeter & Ellipse Fitting

Soft rubber seals rarely sit in a perfect circle. Instead of taking a single two-point chord like callipers, Olypsys fits the entire inner and outer boundary and compensates for ovality and wear.

No Operator Error

Two technicians measuring the same flexible O-ring with callipers or a pi tape will get two different numbers. In the Pro-Vision Booth, inter-phone mean differences are under 0.10–0.37 mm even on a 1.45 m ring.

Desktop Remote Control

Leave a phone mounted in the booth cradle and trigger captures directly from your computer browser at app.olypsys.com, ideal for large 900–1,500 mm booths where the camera sits up to 1.75 m above the stage.

Audit-Ready Cloud Vault

Every capture is logged with its raw image, sub-pixel edge trace, operator, timestamp, and standard match. Generate branded customer PDF certificates or Excel exports in one click.

Production Quality Control

The System of Record for Precision Vulcanized O-Rings

On custom spliced and vulcanized O-rings (from dinner-plate size up to 48″ / 1,219 mm OD and 1,500 mm OD), proving the finished inside diameter after vulcanizing is harder than cutting the cord. A pi-tape pulled snug around soft vulcanized rubber stretches the ID enough to make a borderline ring appear to match the work order even when its free size is out of tolerance.

In ISO 9001:2015 production at The O-Ring Store, the Large-Format Pro-Vision Booth serves as the contactless dimensional system of record to verify finished, relaxed vulcanized rings to ARPM Table 20 Class 2 (±0.80% to ±1.00% ID) and issue customer Measurement Verification Certificates of Conformance (CofC).

Pro-Vision Booth FAQs

Answers on large-ring repeatability, comparison with laboratory optical machines, and what comes in the box.

How does the Pro-Vision Booth compare to dedicated laboratory optical inspection machines?

Dedicated inline and laboratory optical inspection machines are engineered for high-speed factory sorting or metrology rooms and require a substantial capital outlay, custom programming, or multi-shot stitching for large diameters. The Olypsys Pro-Vision Booth ($3,000 for 300 mm up to $27,000 for 1,500 mm) is purpose-built for flexible O-rings, gaskets, and seals up to 1,500 mm ID, with built-in standard matching, cloud traceability, and zero part programming.

How accurate is the Pro-Vision Booth on large O-rings up to 1,500 mm?

On our 1,500 mm Pro-Vision Booth (Grid 54), large-format accurate mode uses 47 centreline control points and photographic edge refinement to compute a circumference-equivalent ID (centreline length ÷ π minus cross-section). Commercial metrology labs we approached turned down the work of certifying these large flexible rings because soft rings over a metre across deform on contact, making manual checks less reliable than Olypsys itself. Across 126 captures on three different phones (Samsung A15, Pixel 7a, OnePlus 7 Pro), component 1450X10A (1540A, ~1,450 mm ID) achieved an all-phone ID standard deviation of 0.09 mm (0.02 mm SD on Samsung A15; 0.07 mm SD on Pixel 7a) and 0.020 mm back-to-back repeatability. Component 1250X8A (1250A, ~1,250 mm ID) achieved 0.17 mm all-phone ID SD (0.09–0.13 mm per phone) and 0.021 mm back-to-back repeatability. Component 400X3A (~400 mm ID) achieved 0.05 mm all-phone ID SD across 52 captures and 5 camera heights, with 0.005 mm (5 µm) back-to-back repeatability.

What is the repeatability on standard-sized O-rings?

On our calibrated steel reference ring (OTCR333-001, ID 62.834 mm, CS 5.353 mm, AML Instruments certificate SW448755889), within-condition repeatability is 0.008–0.009 mm (8–9 microns) ID standard deviation and 0.005 mm (5 microns) cross-section standard deviation on A3/280 Pro Grids.

Why does a large flexible O-ring need circumference-equivalent centreline fitting?

An O-ring with a 1,250 mm or 1,450 mm inside diameter and an 8–10 mm cord never lies in a perfect circle on a table; it settles into a slightly oval or rounded-square lay. Measuring a single diameter with callipers or a ruler gives wildly different numbers depending on which axis you measure. Olypsys traces the entire perimeter of the ring in one shot, fits a 47-knot spline along the true centreline, and divides the total perimeter by π, matching the exact physics of a pi-tape measurement without touching or stretching the rubber.

What is included when I buy a Pro-Vision Booth?

Every Pro-Vision Booth includes the backlit enclosure, a factory pre-calibrated Pro Measurement Grid matched to the booth size, and a 1-year Enterprise software subscription (which unlocks High-Accuracy Mode, desktop Remote Control from your browser, and full Vault access at app.olypsys.com). You simply mount your own iOS or Android smartphone in the top cradle.
