Ultraprecision Molding Suitable for Aspheric Fast-Axis-Collimation Microlenses
The technology yields high-quality microlenses for the collimation of diode lasers and can satisfy the expected demand as lasers and lenses make their way into automotive and consumer applications.
Edgar Pawlowski, Helge Vogt and Dr. Bernd Wölfing, Schott AG
The high-power diode laser achieves the highest level of performance of any laser source. Its compact design, convenient electrical input and extremely high level of efficiency have made it indispensable in a variety of applications, and it can be found more and more in direct medical and industrial applications such as soldering, welding, cutting and surface treatment.
Highly precise optics, however, are required to shape the beam of a diode laser for a particular application. The fast-axis-collimation microlens is the key to a high-quality beam...
