A polarizer wave plate is a kind of optical element. It can change the polarization state of light. Its principle is based on the optical properties of wave plates and the characteristics of polarized light. AS wave-plate is a kind of optical element that can change the phase or polarization state of light. It can be made of glass materials with different refractive indices. Quartz plates are one of the materials. Quartz glass sheets/plates/discs have a wide range of applications in the field of optics. High precision and high transparency quartz plates can be used for optical sensors and instruments. The optical quartz glass plate, as a polarizer wave plate, can be used for measuring the optical properties of biomolecules in the biomedical field. For example, protein structure analysis, cell imaging, etc.
