BVO UV DS is a high durability ultraviolet dyestuff linear polarizer optimized for the 365–450 nm band. The dyestuff construction resists bleaching from high-intensity UV LED and UV lamp sources — the primary failure mode for iodine-based UV polarizers in high-power applications. Purpose-built for LCD/DLP-based 3D printer light engines, UV LED curing systems, and any application requiring sustained high-intensity UV polarization. Available in large panel formats up to 1000 mm × 620 mm for direct lamination to LCD 3D printer panels.
Active range note: BVO UV DS is optimized for 365–450 nm. Above 450 nm Tc rises sharply — this product is not specified for visible or NIR applications. For broadband UV/Vis coverage see

BVO UV DS Linear Polarizer — Transmission Performance
Input Light: Plane Polarized | Optimized Range: 365–450 nm | Note: Tc rises sharply above 450 nm — product not specified beyond active range
Key Features
- High durability dyestuff construction — resists UV LED bleaching and UV lamp degradation
- Optimized for 365–450 nm — the primary UV LED and UV lamp band for 3D printing and curing
- Peak contrast 3,927:1 at 420 nm — excellent polarization efficiency in the UV
- High Tp: 80%+ across the 365–450 nm active range
- Large panel format available — up to 1000 mm × 620 mm for LCD 3D printer panel lamination
- Purpose-built for LCD/DLP 3D printer light engines at 365 nm and 405 nm
- Non-hardcoated polarizer increases damage threshold for high-power UV applications
- Robust PSA conversion available for direct lamination to LCD panels
- Custom geometry — .dxf routing or laser cutting to 10–25 micron tolerances
- BVO vertical integration capabilities for LCD panel polarizer replacement
Performance
BVO UV DS delivers high Tp (80%+) with strong contrast across the 365–450 nm active band. Contrast peaks at 3,927:1 at 420 nm and remains above 2,500:1 from 380–440 nm. Above 450 nm the dyestuff system rolls off abruptly — Tc rises to 1.7% at 460 nm and 35% at 480 nm. This product is strictly for the 365–450 nm band and should not be used outside this range.
The dyestuff construction is the critical differentiator: standard iodine-based UV polarizers bleach under sustained UV LED exposure, losing contrast within hours. BVO UV DS maintains polarization performance under continuous UV LED illumination — essential for 3D printer duty cycles and UV curing lines.
