Description: Setup for very sensitive characterization of the EQE spectrum.
Specifications:
- Wavelength range: 350 nm – 2500 nm
- Very sensitive measurement of low photo-currents by using low-noise preamplifiers and the lock-in technology
- Signal resolution of the EQE in the range of 10-9, d.h. 10-7%
