Nanoparticle Polarizers, 360-5000nm
The working wavelength of the nanoparticle polarizer provided by Tuniu covers 360 nm-5 μm, which can meet the needs of different wavelength bands. Nanoparticle polarizer is a type of absorbing polarizer prepared by embedding ellipsoidal nanoparticles into glass material using semiconductor technology. Nanoparticle polarizers have higher extinction ratios, higher damage thresholds, larger operating wavelength ranges, and larger operating temperature ranges.
The nanoparticle polarizers provided by Tuniu come in two sizes, both of which are available in installed versions. The aperture of the polarizer installed in the standard SM05 lens sleeve is Ø11 mm, and the aperture of the polarizer installed in the standard SM1 lens sleeve is Ø21 mm. We use laser marking to mark the polarization direction on the outer wall of the lens sleeve.
