Ando ANDO AQ-4303B White Light Source

The Ando AQ-4303B is a white light source best suited for loss-wavelength characteristics measurement of optical fibers and devices. This wideband, highly stable light source, which employs a high-power halogen lamp, provides CW light and 270Hz square wave modulated light by the chopper incorporated. The AQ-4303B also incorporates an optical filter that can be readily inserted by switch operation to remove higher-order optical components. Specifications. Wavelength range: 400 to 1800nm. Output stability ± 0.05 dB (at 20°C, for 1 hour). Output waveform: CW or 270Hz chopped light. Output level: - 45 dBm or more (50/125 um GI fiber, wavelength of 850nm and 1300nm, bandwidth of 10 nm, CW). GPIB interface: Supplied as standard.
