Product Description

Composed of quarter-wave plates and polarizing beamsplitter cubes
Design wavelength: 532 nm, 633 nm, 780 nm, 1064 nm, 1550 nm
Transformation of incident unpolarized or P-polarized light into circularly polarized light, elliptically polarized light, or linearly polarized light

The LBTEK Variable Circular Polarizer consists of the quarter-wave plate mounted in an RM05 rotation mount and the polarizing beamsplitter cube installed in a 30 mm coaxial beamsplitter cube mount. The quarter-wave plate, when used in conjunction with the polarizing beamsplitter cube, enables the adjustment and output of linearly polarized light, elliptically polarized light, and circularly polarized light, as well as the modulation of left-handed or right-handed polarized light output. LBTEK offers operating optional wavelengths, including 532 nm, 633 nm, 780 nm, 1064 nm, and 1550 nm. LBTEK provides various customization services, such as custom design wavelengths and high-power versions. For any requirements, please contact LBTEK Technical Support.

Laser Line Variable Circular Polarizers

Design Wavelength: 532 nm, 633 nm, 780 nm, 1064 nm, 1550 nm
Extinction Ratio (Tp:Ts): >2000:1
Low-power Applications

LBTEK combines a polymer true zero-order quarter-wave plate installed in an RM05 rotation mount with a laser line polarizing beamsplitter cube installed in a 30 mm coaxial beamsplitter cube mount to form a laser line variable circular polarizer. The line engraved on the top indicates the optical path direction, with the fast axis of the wave plate aligned to the 0° marking line. The initial position is preset and locked, resulting in right-handed circularly polarized emergent light (observed as left-handed circularly polarized light when facing the beam). The included wrench allows for loosening and rotating the quarter-wave plate to achieve various emergent lights, including elliptically, circularly, and linearly polarized light.

The laser line variable circular polarizer is connected with the Ø12.7 mm post
