LBTEK Polymer True Zero-Order Quarter-Wave Plate (λ/4) (commonly used wavelengths in Quantum Technologies) is based on an N-BK7 glass substrate and liquid crystal polymer birefringence material. By precisely controlling the thickness of the liquid crystal polymer film, the phase difference of π/2 generated by o-light (perpendicular to the optical axis) and e-light (parallel to the optical axis) after passing through the LCP can be precisely controlled, thereby obtaining a λ/4 retardance. The wavelength range: of the Polymer True Zero-Order Quarter-Wave Plate (λ/4) covers multiple commonly used wavelengths in Quantum Technologies within 509 nm~1013 nm, which can meet the experimental requirements of mainstream quantum systems. The Polymer True Zero-Order Quarter-Wave Plate (λ/4) with mechanical housing(s) installed is mounted in standard SM05 and SM1 Lens tubes. The surface of the tube is engraved with the Item and related parameters, and the top of the tube is engraved with a fast Axis marking line, making it convenient for customers to quickly identify and use.

The LBTEK Polymer True Zero-Order Quarter-Wave Plates are based on N-BK7 glass substrates and liquid crystal polymer (LCP) birefringent materials. By precisely controlling the thickness of the LCP film, the phase difference between o-light (perpendicular to the optical axis) and e-light (parallel to the optical axis) can be accurately adjusted to π/2 after passing through the LCP, thereby achieving a λ/4 retardation. The polymer true zero-order quarter-wave plates with mechanical housings are mounted in standard SM05, SM1, and SM2 lens tubes. The tube surface is engraved with the product model and relevant parameters, while the top of the tube features a fast-axis marking line for easy identification and use by customers.

The Polymer True Zero-Order Quarter-Wave Plate (λ/4) has a wavelength range: 670 nm, 780 nm, 795 nm, 850 nm, and other wavelengths commonly used in Quantum Technologies, meeting the experimental requirements of mainstream Quantum Technologies systems. For the Polymer True Zero-Order Half-Wave Plate without mechanical housing(s), the Ø25.4 mm and Ø50.8 mm waveplates use a D-shaped cut edge design with the fast Axis direction parallel to the cut edge, while the Ø12.7 mm waveplate has no cut edge and marks the fast Axis direction with a side scribe line, making it convenient for customers to quickly identify and use.
