The QL01-B offers shot-noise-limited photodetection performance for signal photocurrents as low as 7 nA in a 100-kHz bandwidth and 25 nA in 1 MHz, with a full-scale input of 1 ÁA. The QL01-A trades off a bit of high-frequency noise performance for a 7× increase in detector area, giving more light collection and easier alignment while still being quantum limited above 8 nA in 100 kHz and 45 nA in...See full product
