Variable Multibeam Tool Enables High Accuracy and Throughput

In an article entitled, “Variable multibeam tool enables high accuracy and throughput”, the authors write: Miniaturization drives the industry. While feature densities increase due to the smaller structure sizes required in electronics and display manufacturing, laser scanning speed must also increase to hit throughput targets in terms of moves per second for drilling and other … Continue reading

Diffractive Beam Splitters in Confocal Microscopy

Background: Confocal microscopy Confocal microscopy is a method where illumination is limited to small, diffraction limited spots, resulting in improved resolution. In a classic, single spot confocal microscope, a bright spot is focused on the object, with the scattered light from the object passing through a pinhole, to block out off-focused, scattered light. This results … Continue reading

Diffractive Optical Beam Splitters for Laser Multi-Beam Processing

Background: What is a diffractive beam splitter? Diffractive beam splitters, or multi-spot elements, are a family of diffractive optical elements (DOEs) that split an incoming laser beam into an array of beams with controlled separation angles. This splitting can be along a line (1-D splitters) or into a matrix (2-D splitter), including square, hexagonal or rectangular array … Continue reading
