Used in laser beam expanding, collimation or projection systems, dispersing convergent beams to the virtual focal point, but also through the negative focal length characteristics to extend the total focal length of the system, commonly used in imaging systems or Galileo type beam expander. Multi-band compatibility with customized coatings for combined UV, VIS and NIR applications.
