The EPP2000C Solar concave grating spectrometers and the Dual-DSR Solar model configurations are the perfect tools for making solar irradiance measurements. The solar irradiance monitors are great for solar simulators and artificial lighting of all kinds. The instruments are calibrated to measure the spectral irradiance in units of watts per meter squared over the wavelength range in nanometers. Currently there are standard and extended range EPP2000C Solar models covering 190-850nm/280-900nm or 200-1080nm/230-1100nm, respectively. The Dual-DSR Solar configuration enables irradiance measurements from 200-1700nm. Choose from the list of StellarNet Solar monitoring configurations in the table at the bottom of page.
