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.
Specifications
- 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.
