Matching excimer-laser output to the needs of a particular process requires specific beam shaping and focusing optics. However, clever optical and optomechanical design can deliver the required beam transformations within… Related Searches: beam homogenizer | expander | uv homogenizer

In case of a perfect top-hat (or flat-top) profile the beam diameter is clear but most laser beams have other transverse shapes or profiles (for example, Gaussian) in which case the definition and measurement of the beam diameter is not trivial. The boundary of arbitrary optical beams is not… Related Searches: gaussian beam propagation | beam waist | m2 beam propagation analyzer | mrad

Dirt on an optic does far more than reduce the beam quality; it damages, usually permanently, the optical surface itself. Particulate materials are heated quite strongly by the beam and conduct this heat to the surface… Related Searches: oem manual | oem controller | beam tube | recirculator

Additionally, fewer optical materials are transmissive at UV wavelengths, so the cost of beam delivery optics may increase when operating in this spectral range. Thus, the overall cost of implementation is nearly always… Related Searches: laser basics | telecentric | avia 355 laser | galvanometer
