Problems solved by technology

However, lenses with high numerical aperture are usually more expensive
As for the dual-beam laser, although the dual-beam laser does not need to pass through a lens with a high numerical aperture, since the dual-beam laser needs to apply two lasers at the same time to manipulate the particles, the cost of using the dual-beam laser is also higher

Abstract

The invention relates to a disc structure, a manufacturing method thereof and an optical tweezers device which applies the disc structure. The disc structure is arranged in the optical tweezers device. The optical tweezers device comprises a light source used for generating laser. The disc structure comprises a first substrate, a second substrate and a reflection layer. The first substrate comprises at least one flow channel. The second substrate is arranged corresponding to the first substrate. The reflection layer is arranged between the first substrate and the second substrate, and the reflection layer is adhered on the second substrate. When the laser penetrates the first substrate and is contacted with the reflection layer, the reflection layer reflects the laser, thereby leading the reflected laser and the incident laser to form a light field of the optical tweezers in the flow channel.

Description

technical field [0001] The invention relates to a disc structure, its manufacturing method and an optical tweezers device using it, and in particular to a disc structure with a reflective layer, its manufacturing method and its optical tweezers device. Background technique [0002] With the development of science and technology, the application of optical tweezers devices in micro-electromechanical processes, biological fields or medical fields is becoming more and more common. Current light manipulation technologies include: optical gas pumping, optical levitation, and laser cooling to capture atoms & laser tweezers (Laser Cooling and Trapping). Among them, Arthur Ashkin et al.'s single-beam laser optical tweezers technology is the most widely used. The optical tweezers device uses a lens with high magnification and high numerical aperture (Numerical Aperture, NA) to focus the laser light to manipulate a particle at the micro-nano level at the focus. And because the optic...
