An integrating sphere for the Fluorolog 3 spectrometer from Horiba was funded.

The integrating sphere is shown in the photo and can be inserted directly by the user in the form of an insert into the Flurolog 3 spectrometer from AG Callsen, which considerably simplifies operation.

Measured quantity: The user is then able to measure quantum efficiencies of a variety of samples (layer samples, powder samples, etc.) using this integrating sphere.The supported integrating sphere is the “K SPHERE-Petite” system from Horiba, which has a diameter of 81 mm (compact design) and enables the automated measurement of quantum efficiencies from 320 - 950 nm in the Fluorolog 3 spectrometer.

Feature: A special feature of the entire system is the resulting possibility of measuring quantum efficiencies as a function of the excitation wavelength, which is particularly important for semiconductor heterostructures.
