In-house from design to coating
Unlike catalog resellers, Prismavexa controls the full stack: optical design, CNC polishing, thin-film deposition, and final assembly happen under one roof in our Ashburn facility.
Optical design
Zemax-modeled assemblies optimized for your wavelength band and angular tolerance.
Thin-film lab
Electron-beam and ion-assisted deposition for AR, HR, and notch coatings.
Metrology
Interferometry, spectrophotometry, and environmental stress screening before shipment.
Quality & compliance
Documentation packages that satisfy procurement reviewers and lab auditors.

Full quality manuals and audit schedules available on request for qualified buyers.
About Prismavexa
Prismavexa LLC was founded in Northern Virginia to close the gap between research-grade optics and production-ready spectral instruments. Our name reflects what we build: systems that separate, measure, and quantify light across the spectrum with precision.
We serve university photonics departments, semiconductor metrology groups, environmental testing labs, and defense integrators who need hardware they can calibrate, document, and defend in an audit.
