Not just an integrating sphere – a complete quantum yield solution!

When combined with a HORIBA Fluorometer the Quanta-φ forms the most accurate, versatile and complete luminescence yield system available!

Quanta–φ is a quantum yield and CIE measurement accessory for our Flurolog and FluoroMax fluorometers. Quanta–φ features a large 150 mm (6 inch) integrating sphere, unique bottom-loading solid sample drawer, electrical connection port for EL measurements, all controlled from a simple-to-use dedicated QY/colorimetry software. Combined with our highest sensitivity and flexibility fluorometers, Quanta–φ is finally the headache-free PL/EL QY solution you need.


  • Large 150 mm (6 inch) sphere for higher accuracy and precision QY values
  • Bottom-loading drawer for solid/powder samples, eliminating contamination
  • Top-loading center-mounted liquid sample holder fits any standard 12 mm cuvette
  • Wiring port for light-emitting devices and electroluminescence
  • Complete, easy-to-use analysis package for quantum yields and chromaticity indices
  • Disposable solid/powder cups with optional reusable quartz coverslips
  • Usable with any detector mounted on any port of your fluorometer
  • Instructional video tutorials, electronic user’s manual and on-line interactive help support
