Search this category by sizeOpto-mechanical parts are precision-turned elements that position, align and secure lenses, mirrors, apertures and detectors along the optical axis. They are used in camera and machine-vision modules, laser optics, microscope and endoscope tubes, and metrology and spectroscopy instruments. This category covers 14 families and 151 types: lens holder rings, tube adapters, aperture rings, lens barrels, adjustment rings, hexagonal mounting rings, spacer rings, pinhole apertures, optical shafts, micro-adjustment screws, mounting pins, distance rings and optical posts. They are machined from steel, stainless steel, brass and aluminum, with finishes such as polishing or black anodizing applied on request. We turn them on the Goodway SW-20 Swiss-type lathe across a ⌀1–20 mm bar range, targeting h6 on outer diameters and H7 on bores; ±0.01 mm is targeted on critical lengths and spacings. Beyond the 151 catalog types, we produce custom parts from your technical drawing or sample. Share a drawing or dimensioned sketch and we'll start a quote based on material and quantity.
Length is what varies most here: from 2 mm up to 103 mm at OPTB-PST-12, a span of 101 mm inside one category — and all of it inside the machine's 207 mm single-setup limit. Across 151 variants the work is 47× thread turning, 14× hex flat milling, 103× axial bore, 3× taper turning, 70× knurling.
Tolerances span 7 classes (6H, 6g, H8, h6, h7, h8, m6) and 144 variants carry a DIN or ISO reference. The highest length-to-diameter ratio in the category belongs to OPTB-SHF-01 at L/D 6.7 — slender enough to need tailstock support on a conventional lathe.
Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.
Frequently Asked Questions
As standard we machine steel, stainless steel (304/316), brass and aluminum. Aluminum is common for lightweight mounts, stainless for corrosion resistance and cleanability, and brass for low reflectivity and dimensional stability. Finishes such as polishing, black anodizing or chemical blackening can be applied on request.
On the Goodway SW-20 Swiss lathe we typically target h6 on outer diameters and H7 on fit bores; ±0.01 mm is targeted on critical lengths and spacings. On optical seating faces of lens barrels and aperture rings, concentricity and squareness are inspected to the tolerance on your drawing.
Yes. Beyond the 151 catalog types, we manufacture custom opto-mechanical parts from your technical drawing, dimensioned sketch or an existing sample. Thread, diameter, aperture opening and mounting holes are machined to your specification.
We can run single pieces / low volumes for prototypes and samples; unit cost drops as quantity rises in series production. The exact minimum depends on part complexity and material — the quote includes a clear quantity–price breakdown.
Pricing is quote-based; we don't publish fixed prices online because material, tolerance, finish and quantity all affect the price directly. After you share a drawing we reply and confirm the lead time by quantity together. We have manufactured in Düzce, Turkey since 2009 and ship domestically and for export.
