Dichroic Filters – 45-degree edge filters, Rs > 98%, Tp > 90%. No minimum order; DFM review included with every RFQ.
Selecting dichroic filters starts from the detector, not the glass: split or combine beams by wavelength. The manufacturable window here is 45-degree edge filters, Rs > 98%, Tp > 90%.
Specification envelope
| Optical specification | 45-degree edge filters, Rs > 98%, Tp > 90% |
|---|---|
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Specification advice
The shop-floor rules that matter here:
- 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.
Application context
The recurring buyers of dichroic filters: oled packaging (cover lids, frit-seal frames, fill-port plates); led packaging (groove covers, phosphor carriers, package windows); machine vision (camera windows, ring-light diffusers, calibration plates).
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.
Engineers scoping this work usually also review ultra-thin quartz discs, alkali-free display glass, laser glass cutting.
Common questions
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.
Is there a minimum order for dichroic filters?
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.
