Title:
OPTICAL SENSOR MODULE
Document Type and Number:
Japanese Patent JP2020140177
Kind Code:
A
Abstract:
To provide an optical sensor module with a small amount of ghost image.SOLUTION: An optical sensor module 1 comprises a near-infrared absorption filter 4 including a near-infrared absorption layer between an optical sensor 5 and an optical filter 3 transmitting light of at least part of wavelength of wavelengths 800-1200 nm. When a wavelength, among light incident from a vertical direction of the optical filter, having the highest transmissivity in wavelengths 800-1200 nm is denoted by λOMAX (nm), an average value of transmissivities of light incident from the vertical direction of the near-infrared absorption filter in wavelengths (λOMAX-15) nm to (λOMAX+15) nm is 20-85%.SELECTED DRAWING: Figure 1
