Cleanroom Optical Assembly, from Prototype to Production
Kingsview Optical provides cleanroom optical assembly for optical and optoelectronic systems at our site in Rye, East Sussex. We build and prove your first units, then develop the methods, procedures and inspection plans to make them efficiently in volume, using optics, coatings and mechanical parts made on the same site.
- 3 cleanrooms on site
- Prototype to production
- ISO 9001:2015
- NDA-friendly

A Full Production Run for a Defence Programme
We set up and ran the production line for 22,000 optical units for a defence programme, all assembled here in Rye. It's the same approach we take for smaller volumes: prove the build, write the process down, inspect every stage.
Optical Assemblies We Build
Whether it's a handful of prototypes or a production line, the optics, coatings and housings can all come from our own workshops.
Sealed Lens Assemblies
Multi-element lens systems built in our higher-standard cleanroom, with H14 HEPA filtration for sealed optical systems.
Optoelectronic Assemblies
As optics and electronics are integrated more closely, we develop assembly and test processes for optoelectronic modules too.
Cemented & Aligned Optics
Doublets, triplets and lens groups cemented and aligned in-house, with centration checked on our Trioptics OptiCentric.
Lens manufacturingOptomechanical Housings
Barrels, cells and mounts machined on our own turning centre, so the mechanics are made to suit the optics.
Optomechanical manufactureHow We Take an Assembly from Prototype to Production
- Build and prove the prototypeFirst units are assembled and tested against your specification, so problems show up before anything is committed to volume.
- Develop the methodWe write the assembly method and procedures, working out the most efficient, cost-effective way to build it repeatably.
- Set the inspection planEach stage gets defined checks, using the same metrology we use on our optics: centration, surface form and coating performance.
- Run the production lineFrom small batches to runs of more than 20,000 units, with traceability under our ISO 9001:2015 system.

Three Cleanrooms on One Site
Assembly Cleanroom
Our original cleanroom, with space for optical assembly work that needs a controlled, clean environment.
Higher-Standard Cleanroom
H14 HEPA filters across the ceiling, for assembling sealed optical systems.
Photolithography Room
A dedicated dark room for making reticles and graticules by photolithography or lift-off, using our own vacuum coatings. Custom graticules
Everything That Goes Into Your Assembly, Made Here
One supplier for the parts and the build means one purchase order, one set of test data and no waiting on other suppliers.

Getting a Quote for Cleanroom Optical Assembly
Send whatever you have. If it's still a prototype, that's the best time to talk: we can flag anything that will make volume production harder or dearer.
What to send
- Assembly drawing or 3D model: PDF, STEP or DXF
- Optical specification, or the performance it has to meet
- Volumes: prototypes, first batch and expected annual quantity
- Sealing, environmental or cleanliness requirements
- Test and inspection data you need supplied
What happens next
- An engineer reviews itWithin one working day, flagging anything that will drive cost or lead time.
- We quote the buildFor prototypes, and for production at your volumes.
- We build, inspect and scalePrototype first, then the production line.
Moving an Optical System into Production?
Tell us what you're building and the volumes you expect. We'll tell you honestly how we'd make it, and what it will take.
