Quantum Efficient Measurement System

The QE-2000 by Photal Otsuka Electronics is the latest generation of quantum efficiency (yield) measurement tools, which allow the user to determine QE of powders, liquids, solids and films. An optically optimized geometry using an integrating hemisphere and low stray light array spectrometer (wavelength range 250 nm – 1100 nm) enable world class measurements in applications like LED and OLED materials, thin film state sample, quantum dot, fluorescent probe, biotechnology, clathrate, dye sensitized solar cells and complex chemistry.

Features:
•   Instant absolute quantum efficiency (yield) measurement
•   Re-excitation elimination function
•   Optically optimized geometry using integration hemisphere
•   Low stray light array spectrometer as detector
•   Detection wavelength range 250 nm – 1100 nm

The QE-2000 system has an outstanding accuracy by the implementation of a new re-excitation eliminating function. The compact table top device features a user friendly software, easy cell loading and unloading, selection of the excitation wavelength and a full automated measurement procedure. Various analysis functions like quantum efficiency (yield), excitation wavelength dependency, emission spectrum, FL excitation spectrum and EEM (excitation emission Matrix) are available.

High speed measurements without darkroom and pre-known sample knowledge is no challenge for the QE-2000. An optional version QE-2100 with separate components allows temperature dependence analysis of quantum efficiency and wide detection wavelength range of 300 nm – 1600 nm.

About Sphere Optics:
SphereOptics GmbH was established 2003 along with two partner companies in the United States and France, as well as with a global network of representatives. Because of the merger between  Labsphere Inc. andh SphereOptics LLC in  the US  beginning of 2010 we can extensively serve the market with optical measurement systems and a wide range of integrating spheres, materials and standards for the measurement of diffuse reflectance. We also offer an extensive calibration service to our customers.
We are specialized on the production, refining and calibration of materials and standards for diffuse transmission and reflectance. These are highly pure sintered PTFE products and are sold under the trademark Zenith. Zenith Polymer is the preferred material in the aerospace industry, and in spectroscopy and optical laboratories. For high quality integrating spheres and homogeneous light sources, sintered, porous PTFE is the material of choice.
