Description

Philips Technologie GmbH U-L-M Photonics, a worldwide leading VCSEL supplier!

VCSEL is an acronym for “Vertical Cavity Surface Emitting Laser”, a typical High-Tech product. It is not visible because it is too small. It is not tangible in applications, because it is always built inside modules and boxes and, furthermore the emitted laser light is not in the visible wavelength regime.
