BVO UV Linear Polarizer Family

Coverage: 320 nm – 760 nm  |  Two Absorptive UV Variants  |  Non-Reflective  |  Film, PSA, Glass
Bolder Vision Optik manufactures two absorptive UV linear polarizers covering 320 nm to 760 nm. BVO UV is the cost-effective broadband UV/visible hybrid for general UV instrumentation. BVO UV DS is the high durability dyestuff polarizer purpose-built for 365–450 nm UV LED applications — particularly LCD/DLP 3D printer light engines where standard polarizers bleach under sustained UV exposure.

Which UV Polarizer? — Application Selector

If your application is...ChooseWhy
UV fluorescence polarization (FP) BVO UV 320–760 nm covers UV excitation and visible emission in one element
Microplate readers BVO UV Broadband UV/Vis, high VIS Tp, cost-effective OEM volume
UV/Vis microscopy BVO UV Single element covers UV excitation through visible imaging
Semiconductor UV inspection BVO UV 320–400 nm UV coverage, cost-effective, available in glass components
LCD/DLP 3D printer light engine BVO UV DS Resists UV LED bleaching, large panel format to 1000×620 mm, 365/405 nm optimized
UV LED curing systems BVO UV DS Maintains contrast under sustained high-intensity UV LED — standard polarizers bleach
365 nm or 405 nm UV illumination BVO UV DS Peak performance at 405–420 nm, 3,927:1 contrast, 80%+ Tp
Need coverage below 365 nm BVO UV BVO UV active from 320 nm — BVO UV DS not specified below 365 nm
Need coverage above 450 nm BVO UV BVO UV DS Tc rises sharply above 450 nm — BVO UV covers to 760 nm
