µ-GRIN optics: New versatile µ-imprinting process of refractive index gradient

APPLICATIONS

This technology is a new imprinting method allowing to manufacture micro-GRIN optics (micro-lenses, waveguides…) with unique properties useful in many fields as:

• Infrared camera,
• Microscopy,
• Plenoptic camera,
• Laser applications,
• CMOS and CCD sensors,
• Photovoltaic.

DESCRIPTION

The optical elements are directly formed on a wide variety of vitreous compositions to target transmission from visible to mid-IR spectral domain.

BENEFITS

Transmission window: visible or mid-IR (350 nm to 10 µm) depending on the glass composition
Large variety of structures (dots, squares, lines…) from 2 µm to 300 µm – on demand.

IP

This technology is the subject of a European patent application
