Thorlabs.com - Modular Optical Tweezers

Thorlabs' Modular Optical Tweezers System uses a 976 nm, 300 mW laser. Exposure to the laser beam is possible, and the system should be treated as a Class 3B laser. Appropriate safety procedures and care must be taken including, but not limited to, the use of laser safety glasses. More details about the laser classification

Koch Lab:Protocols/Optical Tweezers - OpenWetWare

Optical Tweezers are simple in theory but are not very simple in setup. This is why we are going to detail our setup so that others may replicate. The other reason for this section is because different people build different tweezers for different applications. We require one tweezer with sample control coming from stage movement.

Optimization of Optical Tweezers

Optical Tweezers Theory The basic concept behind the optical tweezers is that a change of momentum in light will hold some small particle confined in the focus of the trapping laser beam. This change in the momentum of light is due to the difference between the refractive indices of the particle being trapped and the surrounding medium.

Optical tweezers can also be used to micromanipulate an object using well-controlled forces. Trapped by refraction. The trapping force that holds an object in place in optical tweezers can be understood by considering how the object refracts light. Because it is tightly focused, the laser light is most intense at the centre of the trap, which ...
