DITZINGEN, Germany — TRUMPF entered a strategic partnership with LAYERTEC, a manufacturer of precision optics, whereby TRUMPF will invest in a range of machinery for the manufacture of large optical components. Some of this machinery has been acquired from optics specialist Berliner Glas, according to a press release. The large optical components are used in TRUMPF laser systems, which are designed for the production of OLED displays, among other applications.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookRadiometry: A Simplified Description of Light Measurement: Radiometry involves measuring and predicting levels of optical radiation.
