600–1100 nm λ/2 Achromatic ±0.01 waves NIR Broadband Off-Shelf $595
AHWP6 is BVO's broadband NIR achromatic half waveplate covering 600–1100 nm with visible wavelength overlap. Rotates the incoming plane of polarization by twice the optic axis angle across the full NIR band — eliminating the need for multiple single-wavelength NIR waveplates. True zero order multi-layer fused polymer construction. Popular for NIR imaging, NIR analytical instrumentation with LED and laser diode sources, and multi-wavelength NIR systems.
