Machined Components for Optical Assemblies
The optics get the credit; the mechanics do the work. Mounts, spacers and benches hold alignment through temperature cycles, vibration and time — and that is entirely a machining problem.
Why equipment manufacturers choose us
Hermetic bodies in Kovar
Kovar housings and feedthrough components with spectrometer-verified chemistry — the glass-sealing alloy, machined correctly.
Stability against drift
Invar and other low-expansion options where thermal growth would move the optical path.
Seating surfaces that behave
Ra 0.2 µm finishes and controlled geometry on lens seats, spacers and adjustment threads.
Optical Components
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Typical parts | Lens mounts and retainers · spacers · optical benches · adjustment rings · hermetic bodies |
| Materials | Aluminum · stainless · titanium · Kovar · Invar |
| Typical tolerance | ±0.005 mm typical where applicable · ±0.01 mm standard |
| Surface finish | Down to Ra 0.2 µm |
| Processes | 3- and 5-axis milling · turning · Swiss-type |
| Inspection | Zeiss CMM · spectrometer verification for Kovar and Permalloy |
| Prototype lead time | Typically 5–10 working days |
Materials we machine
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
