Laser Power Measurement Spheres and Sensors

Accurate and reproducible tools for hard to measure laser products

In various applications such as VCSEL-based LIDAR and facial recognition systems, the necessity arises to simultaneously assess multiple attributes of a laser beam, encompassing power, spectrum, and temporal pulse shape. Coping with the challenge of capturing and accurately measuring these collimated to divergent, continuous, and pulsed sources, can be highly intricate. Labsphere’s assortment of multifunctional laser power integrating spheres and sensors offers an effective solution to surmount these difficulties.

Labsphere’s laser power measurement spheres and sphere sensors provide options for sphere size and coating which are determined by the test laser power levels, the sphere optical detectors which are dictated by the test laser wavelength, and spectral responsivity calibration of the range of the optical detectors.

Value
  • Ensure comprehensive power collection from a laser, regardless of divergent angle or polarization
  • Efficiently attenuate high power to avert sensor saturation
  • Incorporate the second detector port for spectral monitoring or expanded wavelength coverage
  • Mitigate errors linked to the non-uniform response of sensor active areas in their bare state
