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
