Abstract
An infrared light sensing device includes a substrate, a light source module, a light sensing module, a barrier structure and a protective cover. The light source module, the light sensing module and the barrier structure are arranged on the substrate, and the barrier structure is used to isolate the light source module and the light sensing module. The protective cover is bonded to the barrier structure and includes a plate, a first bandpass optical film and a second bandpass optical film. The first bandpass optical film is disposed on the plate and faces the light source module, and the first bandpass optical film corresponds to a first infrared light spectrum range. The second bandpass optical film is disposed on the plate and faces the light sensing module, the second bandpass optical film corresponds to a second infrared light spectrum range located within the first infrared light spectrum range.
