Description
Photonchina specializes in the production of high-quality waveplates, essential optical components that transform the polarization state of light. These precision-crafted optics exhibit polished surfaces that contain the optical axis, allowing light to interact in a unique manner. Light entering the waveplate normal to its surface is split into components polarized parallel and perpendicular to the optical axis. This interaction results in a phase shift, known as retardance, between the two components. Photonchina's expertise lies in manufacturing quarter and half wave retarders, which are the most popular choices for various optical applications.
Photonchina's waveplates are engineered to transmit light while modifying its polarization state without causing attenuation, deviation, or displacement of the beam. This makes them ideal for applications requiring high damage thresholds and stable retardation over temperature changes, such as laser systems and infrared light sources. The waveplates are crafted from high-quality quartz materials, cut and polished to exacting standards. They feature a laser-quality finish, arcsecond parallelism, and a wavefront of less than λ/10, ensuring superior performance and reliability. The production process at Photonchina involves precise cutting of quartz materials with axes oriented to within a few arcminutes.
The waveplates are then polished to achieve the desired optical properties and coated with anti-reflective layers. Zero order and achromatic waveplates are meticulously matched in pairs and aligned within their cell mounts to guarantee optimal performance. With a wide range of standard wavelengths available, from 355 nm to 1590 nm, and custom options within 200-2300 nm,
Photonchina caters to diverse optical needs. Photonchina's commitment to quality is evident in their stringent specifications, including dimension tolerances of +0.0, -0.1mm, wavefront distortion of less than λ/8 at 632.8 nm, and retardation tolerance of less than λ/500. These specifications ensure that each waveplate meets the highest standards of precision and performance, making Photonchina a trusted partner for advanced optical solutions.
