BEAM GENIE

Laser Beam Stabilizer

The Beam Genie  is a compact solution that actively compensates for laser beam misalignment due to thermal shifts in laser pointing, maintaining proper aiming of a laser beam to its intended target.

For applications to flow cytometry, the Beam Genie keeps a laser beam locked onto the sample core stream, reducing variations in the precision of measurements and keeping Coefficients of Variation (CVs) low. The Beam Genie is:

  • customizable
  • retrofittable
  • standalone
  • automatic
  • compact

Live demo of Beam Genie. The actual device is fully enclosed inside the orange hand (see Specifications for dimensions).

Performance of Beam Genie. Red triangles show beam misalignment with respect to core stream as the pointing direction sweeps (without Beam Genie);  green circles show the beam tracking the core stream (with Beam Genie).
