The dual LED series consists of a 660nm and a companion 890nm (IR). They are widely used in medical analytical and monitoring devices. They can also be used in applications requiring a low cost Bi-Wavelength light source.
The matching photo detectors' responses are optimized for maximum responsivity at 660nm as well as near IR wavelengths. They exhibit low capacitance and low dark currents.
