Quick answer: Longpass Optical Filters covers cut-on 400 – 1500 nm, slope < 2% of edge. Prototypes ship in 5-10 working days.
Selecting longpass optical filters starts from the detector, not the glass: pass long wavelengths, block excitation light. The manufacturable window here is cut-on 400 – 1500 nm, slope < 2% of edge.

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
longpass optical filters shows up across led packaging (groove covers, phosphor carriers, package windows); semiconductor equipment (view ports, wafer carriers, plasma rings, chamber windows); oled packaging (cover lids, frit-seal frames, fill-port 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 AR optical windows, alkali-free display glass, glass wafer coring.
Common questions
Is there a minimum order for longpass optical 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.
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.
