The Ando AQ4303C is a broadband white light source for optical component and system testing across the 400 nm to 1800 nm wavelength range. Built around a high-power halogen lamp, it delivers stable, continuous output suitable for fiber characterization, spectroscopic measurement, and laboratory R&D. The instrument supports both CW and 270 Hz chopped square-wave modes, with output stability of ±0.05 dB over one hour at 20 °C. A selectable built-in optical filter removes higher-order components, enabling clean spectral analysis across the visible through shortwave infrared bands.
