Abstract:
A lens module includes an infrared absorbing filter. The infrared absorbing filter includes an electrochromic substrate. The electrochromic substrate changes from colorlessness to blue when a preset voltage is applied on the electrochromic substrate. The electrochromic substrate is configured for absorbing the infrared constituent of incoming light rays when the color is changed to blue.
