Quick answer: Optical Glass for CCD Inspection Equipment covers Optical Glass (CTE 7.1 x 10^-6 /K, 350 nm – 2.0 um). Prototypes ship in 5-10 working days.
What optical glass for ccd inspection equipment actually buys from a glass shop: CCD cover plates, reference grids, stage glass. The requirement underneath is large-format screening plates with sub-micron cleanliness. Optical Glass is the fit here because it offers certified refractive index and dispersion.

Specification advice
The shop-floor rules that matter here:
- Material note: index-certified blanks must be oriented and serialized through the shop to keep melt traceability.
- 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.
Capabilities and limits
One material, many routes: on Optical Glass we also quote polishing, etching, edge grinding, sandblasting, and multi-step drawings are the norm rather than the exception.
Where these parts end up
Orders for optical glass for ccd inspection equipment cluster in scientific instruments (reference flats, cells, prism mounts, stage inserts); machine vision (camera windows, ring-light diffusers, calibration plates); laser systems (windows, beam splitters, debris shields).

Frequently asked questions
How does Optical Glass behave under heat?
CTE is 7.1 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where certified refractive index and dispersion matters.
What do ccd inspection equipment programs usually order?
CCD cover plates, reference grids, stage glass. Typical spec: particle spec Class 100 packing, flatness 5 um.
Is there a minimum order for optical glass for ccd inspection equipment?
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.
