Custom chromium features on flat glass create functional optical patterns for sensing, inspection and instrumentation. The geometry follows your artwork.
Custom opaque chromium features and transparent areas turn flat glass into an optical component. A single drawing may combine lines, apertures, reference marks and identification. The film pattern and substrate geometry are controlled as separate features.
Use this route for a pattern that does not fit a standard product family. Describe what the pattern does in the instrument so critical features can be identified.
This route combines optical features that do not fit one standard reticle or target layout. A photomask is used to transfer a pattern; functional patterned glass usually remains in the finished instrument.
Combine transparent windows, opaque regions, periodic lines, identification and datum marks. Substrate shape, thickness, coating side and useful optical field are independent choices within the instrument design.

| Functional regions | Clear windows, opaque patterns and reference marks |
|---|---|
| Pattern datum | Feature coordinates relative to the mounting reference |
| Optical mode | Transmission or reflection at the specified wavelength |
Inspect the agreed critical dimensions, registration and clear/opaque defects against the approved drawing revision.
Opaque film and clear regions can form lines, windows, scales and location marks on the same substrate. This is useful when a standard reticle or target does not include the required combination. Define which areas transmit light, which block it and which serve only as identifiers.
A window may define a viewing field while nearby fiducials locate that field for a camera. Their relative position may matter more than the overall plate size. Specify the functional relationships and mounting datum so that separate features can be inspected as one component.
A clear region in chromium leaves the glass beneath it intact. Steps, cavities or physical through-holes require a separate machining route. State whether the component works in transmission or reflection, because opacity alone does not establish reflected contrast.
| Control item | Information to confirm |
|---|---|
| Geometry and position |
|
| Substrate and optical path | Specify glass grade, thickness, wavelength and illumination side. Review transmission and reflections in the actual optical arrangement. |
| Inspection and acceptance | Inspect the agreed critical dimensions, registration and clear/opaque defects against the approved drawing revision. |
| Drawing and revision | Provide a 1:1 DWG with declared units, clear and opaque layers, viewing direction, active area and the approved revision. |
Custom functional artwork combining several feature types.
Drawing-defined glass reticles for the viewing reference required by an optical instrument.
Yes. Supply one coordinate system and identify the critical relationship between the patterns and the mechanical outline.
Chrome-patterned glass uses drawing-defined transparent and opaque structures as functional patterns in optical instruments.
Define the pattern, polarity, physical outline and mounting datums together. The optical aperture remains supported by glass unless a mechanical opening is specified.
Artwork, dimensions, substrate, thickness, film side, polarity and inspection datums.
Artwork defines the functional geometry; the mechanical drawing defines outline, thickness and location. Together they define the component.
