Si Photodiode Arrays for UV to NIR Low-Light-Level Detection – S4111/S4114 Series

The S4111/S4114 series are Si photodiode linear arrays, which are mounted on ceramic Dual Inline Packages (DIPs). These photodiode arrays are mainly developed for low-light-level detection such as spectrophotometry, and cover a broad spectral range from UV to near infrared (NIR) light.

As all elements can be utilized with a reverse bias for charge storage readout, the S4111/S4114 series are capable of sensing low level light with high sensitivity. Crosstalk between elements is reduced to preserve signal purity. Special filters can be linked as the input window.
