S6174, S6874-10, S8041
S6174, S6874-10, S8041 are designed for laser beam synchronous detection in laser printers, etc. These photo ICs use a single-element
photodiode and a signal processing circuit integrated in a small package. For more precision printing, Hamamatsu also provides S5049 series
photo ICs using a dual-element photodiode.
