Overview
About the SS-L140 / SS-L300
Independently driven LED channels allow the illumination spectrum and total irradiance to be adjusted in software. Saved settings, lamp-board temperature monitoring and power correction support repeated measurements.
Effective illuminated areas are specified at a 3 cm working distance. Available spectral shapes depend on the maximum output of each channel and the total permitted electrical power.
Features
- Programmable spectral profiles and saved illumination settings
- Constant-current drive with temperature monitoring
- Software operation and external control buttons
Applications
- Perovskite and tandem-cell research
- Steady-state photovoltaic I–V measurements
- Semiconductor and photoelectric materials testing
