Abstract
An infrared light detector has a first substrate having a sensor chip thereon that has an exposure surface that can be irradiated with infrared light, the sensor chip converting the incident infrared light into an electrical signal. The infrared light detector also has a second substrate having a window therein that is located adjacent to the exposure surface of the sensor chip, the window masking infrared light of a predetermined wavelength. The size (dimensions) of the window and the distance of the window with respect to the exposure surface are dimensioned to cause infrared light passing through the window to completely strike the exposure area of the sensor chip.
