BVO 244 is BVO's highest single-pass transmission visible linear polarizer — 86.6% average Tp across 400–700 nm. Where BVO UHC maximizes contrast, BVO 244 maximizes transmission efficiency. The trade-off is lower contrast (460:1 average) — BVO 244 is chosen when Tp is the primary requirement and moderate contrast is acceptable. Ideal for multi-stage optical filter systems where cumulative insertion loss is a concern, HUD displays, and applications where every photon counts.

BVO 244 Linear Polarizer — Transmission Performance
Input Light: Plane Polarized | Active Range: 400–700 nm | Highest Tp in BVO visible line — lower contrast trade-off
Key Features
- Highest single-pass Tp in the BVO visible line — 86.6% average (400–700 nm)
- Minimum insertion loss — ideal for multi-stage systems where losses compound
- Peak Tp 91.2% at 700 nm
- Absorptive, non-reflective — no back-reflection artifacts
- Large sizes available — contact BVO for format options
- PSA conversion available for direct lamination
- Custom geometry — .dxf routing or laser cutting to 10–25 micron tolerances
- Note: contrast is lower than BVO UHC — choose BVO UHC when high contrast is the priority
