The Ando AQ4303B is a broadband halogen lamp source spanning 400–1800 nm, engineered for precise optical loss and spectral characterization of fibers and components. It delivers ±0.05 dB output stability over one hour and operates in continuous wave or 270 Hz square wave modulated modes. A selectable built-in optical filter removes higher-order components to maintain signal purity. GPIB control enables automated integration into test systems.
