We provide scientists and businesses with spectral vision solutions to enable cleaner and safer decisions.

Technology

Traditional cameras measure the light intensity but cannot extract spectrum and polarization information.

Multispectral solutions are becoming more preferable as they optimize the functionality of imaging, speed, throughput and cost within devices such as cameras, sensors etc.

We developed advanced Multispectral solution through:

The use of passive multipass filter combined with broadband LCTF
The use of 2 LC retarders that compensate each other’s retardation dispersion.
Polarization independent solutions: Special LC devices such as Annular SLM, OASLM, Tunable scattering devices.

Complexity

By varying the wavelength and polarization of the light, images with additional information are recorded.

Example: Chromophores in skin lesions absorb the blue and green different from the red and near infrared wavelengths.

Polarization gives information on the collagen fibers status and orientation.

Performance

Our technology offers 9 wavelengths tunable in less than few seconds. It Can be tailored to the specific application.

Polarization images giving ellipsometric parameters in less than few seconds.

Ability to provide full polarization information when combined with polarization mask.

Light throughput >70%.

Custom solutions for larger number of wavelengths and different ranges.

Size & Affordability

Present solutions are bulky, slow in speed, expensive, complex, large form factor, hard to integrate and therefore not adequate for implementations in mobile phones.

Additional 50mmx50mmx50mm unit attached to existing cameras.

Speed: <16msec response time between different wavelengths or polarization states.

The price of current solutions is half the price of existing cameras giving spectral and
polarization images.
