Transmissive Spatial Light Modulator

Our transmissive hexagonal array SLMs are designed for adaptive optics applications. The two dimensional array of Liquid Crystal Variable Retarders acts as a real time programmable phase mask for wavefront correction of a linear polarized source.
Unwanted aberration effects are removed by introducing the opposite phase shift through the Hex SLM. The most common applications involve high-resolution imaging where viewing through an aberrant medium is unavoidable. Examples include astronomical imaging with ground-based telescopes and medical imaging through body fluids. High-energy laser users also benefit from active phase compensation for beam profile correction.

SLM Optics Kit

Spend your time on important research rather than designing an optical system for your SLM. The SLM Optics Kit provides you with a set of optics and cage-mount components enabling the user to start research with the SLM system immediately. The kit includes a Half-Wave Retarder, a pair of Linear Polarizers, lenses, and all necessary mount hardware, including a custom adapter plate to quickly align the SLM system to the optics in an off-axis configuration. Optional items are also available including a laser, beam expander optics, and a camera. This approach provides optimum efficiency with minimal design effort.


Optics Kit includes:

  • Polarizers and waveplates

  • Beam expander

  • Lenses

  • Tip/tilt stage

  • Base plate and posts

  • Laser and camera (optional)

Optical Tweezers Cube

Our Cube provides researchers with a portable, stand-alone, optical tweezers system just one cubic foot in size. This compact instrument allows a user to optically trap and thus physically manipulate hundreds of microscopic objects in three dimensions (3D) using computer control to set and move each optical trap independently.
Optical trapping can be used to manipulate objects ranging in size from 10s of nanometers to 10s of microns and objects with a variety of material characteristics. Trapping examples include cellular organisms, dielectric spheres, metallic spheres, metallic nanoshells, carbon nanotubes, air bubbles, and even water droplets in air.
One application of the CUBE includes biological research. This tool enables measurements of cell properties and controlled studies of how cells interact with foreign objects. Another application example is trapping metallic objects and carbon nanotubes for engineering materials with unique thermal and electrical properties.

 

KEY FEATURES

  • Complete optical trapping system

  • 3D particle manipulation using holographic beam control

  • 100s of traps (demonstrated 400)

  • High temporal trap stability

  • Spatially uniform trapping across 200x200 micron field of view
