Material photo-thermal performance test platform based on polarized light

Abstract

A material photo-thermal performance test platform based on polarized light comprises a test protection device, an optical device and a temperature detection device. And the test protection device is used for preventing light emitted by the optical device from leaking to the outside and comprises a cuvette. The optical device comprises a first polarization beam splitter and an optical power meter arranged in the light emitting direction of the first polarization beam splitter. And the temperature detection device is used for detecting the instant temperature, the highest temperature and the lowest temperature of a detected object when the light is projected to the detected object in the cuvette. The material photo-thermal performance test platform can realize material photo-thermal performance test with adjustable linear and circular polarized light, can test solid samples and liquid samples, particularly can test chiral materials, and better meets actual test requirements. Meanwhile, the thin film polarization splitting prism is used, the linear deviation degree of laser emitted by the laser is purified, the transmittance is higher, and the laser loss is smaller.

Description

technical field [0001] The invention relates to the technical field of optical design, in particular to a test platform for photothermal properties of materials based on polarized light. Background technique [0002] Photothermal therapy is a non-invasive advanced treatment technology that converts near-infrared light into localized heat to induce cell death, which has been proved to have important application prospects in the treatment of major diseases. Therefore, the development of efficient photothermal conversion materials is a prerequisite for the use of photothermal therapy, and therefore the photothermal performance testing of photothermal materials is an essential work for the study of such materials. In addition, it is well known that chiral materials absorb differently to left-handed and right-handed circularly polarized light, and higher photothermal conversion efficiency may be obtained under the excitation of left-handed and right-handed circularly polarized li...
