S7686

Photodiode with sensitivity close to spectral

luminous efficiency

www.hamamatsu.com

S7686 is a Si photodiode having a spectral response characteristic that is more similar to the human eye sensitivity (spectral luminous

efficiency) than our conventional visible-compensated sensors (S1133, etc.).
