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.
Kovar housings and feedthrough components with spectrometer-verified chemistry — the glass-sealing alloy, machined correctly.
Invar and other low-expansion options where thermal growth would move the optical path.
Ra 0.2 µm finishes and controlled geometry on lens seats, spacers and adjustment threads.
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 |
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Kitted, ESD-safe or cleanroom packaging, with local engineering and after-sales support through our German partner.
