Ando AQ-4137B Stabilized Light Source MF

The Ando AQ-4137B Stabized Light Source can accommodate up to two channels. Both LED and LD light source units of various wavelengths are available to allow many configurations. Incorporation of a thermostat/ temperature compensation circuit ensures high optical output level stability. Since the output level can be attenuated up to 6 dB in steps of 0.1 dB, the AQ-4137B can be used for accurate characteristics measurements at the same optical output level, etc. Features. Plug-in-type unit allows a wide choice of light source units-both LED and LD-with various wavelengths(660, 850, 1300, 1310, 1550, 1310/1550 nm). Optical output level can be attenuated from 0 to 6 dB continuously (in steps of 0.1 dB). Capable of producing CW light and 270 Hz chopped light. GPIB standard. Internal modulation frequency: Square wave 270 Hz ± 0.5Hz.
