Terahertz wave vertical exposure system for cell experiment

Abstract

The invention provides a terahertz wave vertical exposure system for cell experiment. The system comprises a terahertz wave source, a convergent lens, a lifting table, an incubator, a gas change box and a carbon dioxide gas cylinder; a light-emitting opening of the terahertz wave source is upwardly placed; the convergent lens is arranged above the light-emitting opening; the lifting table is erected above the convergent lens, and a first through hole is formed in a table surface of the lifting table; the incubator is arranged on the lifting table, a second through hole is formed on a bottom wall, and a gas change inlet and a gas change outlet are formed in a sidewall; an exhaust fan is arranged in the incubator; an ultraviolet disinfection lamp is arranged in the gas change box, a gas inlet on the sidewall of the gas change box is connected with the gas change outlet, and a gas outlet is connected with the gas change inlet; the carbon dioxide gas cylinder is connected with the gas change box; the medial axes of the light-emitting opening of the terahertz wave source, the convergent lens, the first through hole and the second through hole are coincident. The exposure system disclosed by the invention has the advantages of being stable in terahertz wave, short in optical path, and low in attenuation, and the repeatability and the precision of the exposure experiment can be obviously improved.

Description

technical field [0001] The invention belongs to the field of electromagnetic radiation biological effects and the field of experimental technology equipment, in particular, the invention relates to a terahertz wave vertical exposure system for cell experiments. Background technique [0002] With the advancement of science and technology, terahertz waves have gradually entered people's production and life. This electromagnetic wave with thermal effect, high penetration (non-polar substances, non-metal), high information load, and low energy has great application prospects. . Humans are increasingly exposed to terahertz radiation. The overlapping of the terahertz wave frequency and the resonance frequency of biological macromolecules also makes people speculate that it may have a unique non-thermal effect. The biological effects of terahertz waves have gradually attracted people's attention. [0003] In the study of the biological effects of terahertz wave cells, because of...

AI Technical Summary

Problems solved by technology

In this reflective optical path, the overall stability of the optical path is extremely high, and any small error will cause a huge change in the optical path, which requires cumbersome maintenance and testing.
