Spatial Light Modulator-Based Optical Tweezer System
Product Briefing
Single Beam Optical Tweezers-SOT Series
Optical tweezers system is divided into single beam optical tweezers system and holographic optical tweezers system. Single-beam optical tweezers system is mainly composed of four parts: laser module, dichroic mirror module, motion control module and illumination module, which can use the laser force to freely grasp and manipulate particles to move, and connect to the computer through the CMOS camera, which can real-time display the movement of the laser-manipulated particles.
Holographic Optical Tweezers - HOT Series
Equipped with a holographic module based on a spatial light modulator (SLM) and loaded with various new types of light fields, such as vortex beams, Bessel beams, and Airy beams, the HOT series realizes diversified manipulation of target particles.

Applied Directions
As a non-invasive mechanical manipulation system, optical tweezers can be applied to basic research in cell biology, aerosol science, physical chemistry and other interdisciplinary research, including cell microenvironmental changes, deformation stretching, measurement of particle mechanical parameters, etc.. Optical tweezers can also be combined with image recognition to achieve automatic particle capture and sorting; optical tweezers and optical microscopy can be combined to quantify the kinetic properties of cells and molecules, which has a huge research space in cell biology.
