Introduction to Shade-In Element™ Technology
Pixer’s core technology lies in the fields of femtolaser, optical element insertion into a clear media (e.g. glass, quartz), physics, scanning algorithms, state-of-the-art optical instruments and other associated technologies. The company holds multiple patents in these fields.
Side view of a Shade-In Element™
- Each pixel acts as a small scattering center due to small Δn
- The pixel is “written” at 3175um off the Chrome, but can go down to 300um off the Chrome (non-standard)
- Many pixels make one cluster
Model of a Pixel
- The minimal cluster size is 25×25um (@ wafer level)
- Each cluster acts collectively as a large scattering center
Density and Refractive Index of Idealized Pixel
Parameters which affect the threshold for optical breakdown are:
- Wavelength
- Pulse duration
- Pulse energy
- Focusing NA
- Beam quality
- Type of transparent media (band gap)
