Single beam gradient force optical traps, or tweezers, are a powerful tool for a wide variety of experiments in physics, chemistry, and biology. We describe how to build an optical tweezer with a total cost of ≈$6500 using only commercially available optics and mounts. We also suggest measurements that could be made using the apparatus.

If the index of refraction of the object is smaller than the index of the surrounding medium, then the refraction would result in a force that ejects the particle from the trap.

In this discussion we characterize the laser beam with a definite diameter. Typical laser beams propagating in the z direction have an intensity profile Best trapping is obtained when the waist is approximately
