ColorIR™ NIR Tunable Filter

A tunable filter that enables a unispectral NIR image capturing using a standard IR micro camera.

The MEMS filter is applied to any micro IR camera [consumer, professional, stationary or mobile] to convert it into a multispectral authentication, detection and inspection device.

  • Very low cost – very small size
  • Range: 10’s cm .. meter’s
  • NIR illumination: uniform and does not disturb users
  • Resilient to extreme environmental conditions, temperature range, noise, mechanical shock, etc.
  • Can be integrated in dual aperture configuration
  • Flexible architecture
  • Low power electrostatic actuator

Operation:

  • Multi exposure camera, each frame captured at different wavelength
  • Wavelengths selected by applying different voltages on MEMS
