Elliot Scientific E3100 Optical Tweezer System

The E3100 Optical Tweezer System is a simple, pre-aligned, fully interlocked, laser workstation for single beam trapping and manipulation of micron sized particles. It incorporates all the key items of hardware within a self contained desktop instrument.

The standard version has been designed as an economical entry-level product to enable non-specialist users to evaluate the technique in a safe class 1 laser environment. For more advanced applications that require higher laser powers, the unit incorporates an optical input port for introducing an external laser source.

Features

  • Cell manipulation via conjugate beam steering optics or precision XY stage
  • XYZ trapping using variable focus stage
  • All essential hardware is within the desktop workstation
  • Laser in fully interlocked Class 1 enclosure
  • Facility for using an external laser
  • Rotation of birefringent particles with optional polarization optics
