Precision Components for Optical & Photonics Equipment
Optical and photonic instruments punish every micron: a mount that drifts with temperature or a housing that leaks ruins the measurement. We machine the mechanical side of photonics — stable structures, precise mounts and hermetic Kovar packages — with finishes and tolerances the optics deserve.
Why equipment manufacturers choose us
Hermetic packages in Kovar
Kovar housings and feedthrough parts with spectrometer-verified chemistry — the glass-sealing alloy, machined right.
Thermally stable structures
Invar and low-CTE material options where expansion would distort the optical path.
Finish and geometry for optics
Ra 0.2 µm surfaces and ±0.005 mm typical tolerances on seating and alignment features, CMM verified.
CNC Machining for Optical & Photonics
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Typical parts | Lens and detector mounts · optical benches · hermetic housings · adjustment mechanics · sensor 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 chemistry verification (Kovar/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.

What happens after you send your files
- Within 1 business day an engineer — not a salesperson — reviews your drawings and replies.
- DFM review: tolerances, material and risk flags, before any cutting begins.
- Your quote includes a material-verification plan: grade, EN/DIN check, certificate strategy.
Critical features are verified in house · material chemistry confirmed by spectrometer · EN 10204 3.1 certificates available.
