Infrared Optical Windows: fused silica to 2.5 um, sapphire referrals beyond. Single-piece prototypes to production volumes, quoted from your drawing.
infrared optical windows do one job: protect thermal sensors without signal loss. Ours are built to fused silica to 2.5 um, sapphire referrals beyond and cut, edged and mounted to whatever outline the housing needs.

Specification advice
Three items decide most of the cost and lead time on this work:
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Where these parts end up
Orders for infrared optical windows cluster in ccd inspection equipment (CCD cover plates, reference grids, stage glass); mems devices (cap wafers, TGV substrates, motion-sensor lids); scientific instruments (reference flats, cells, prism mounts, stage inserts).

Frequently asked questions
Is there a minimum order for infrared optical windows?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
