Custom optics
If it transmits, reflects, or splits light — we’ve made one.
Submit your drawing or specification and our applications engineering team will respond with a quotation within one business day. If any requirement needs clarification, we confirm before quoting.
What we routinely build
- High Laser Damage (HLD) waveplates — zero & multiple order, 10–50.8 mm
- Achromatic waveplates — quartz + MgF2, flat retardance over 200 nm bands
- DUV lithography windows & mirrors — 193 nm, 248 nm, 157 nm
- Micro-lens arrays & beam splitters for inspection and alignment
- IR windows, flat mirrors & assemblies for defense sensors (Ge, Si, SiC)
- Zero-order, achromatic & partial-wave waveplates — any λ 237–2021 nm
- Polarizing & non-polarizing beamsplitters, narrow or broad band
- Windows & mirrors to 800 mm, round / square / custom shapes
- Lenses & micro-lenses 0.5–350 mm
- Bandpass, short/long-pass & dichroic filters (IBS)
- High-power AR / HR / beamsplitter coatings, 193 nm–10.6 µm
- Prism assemblies, beam combiners, collimators, scan optics
- Large optics — 10 in Dove prisms, scanner prisms & more
