Vortex Plates for STED Microscopy

Introduction Stimulated Emission Depletion (STED) microscopy is a well-known technique for achieving super resolution in microscopy that enables resolving sub-micron details that are smaller than the diffraction limit of the optical system. Developed to bypass this diffraction limit of light microscopy, which is the main limit to the resolution of traditional light microscopes, STED creates … 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

Holo/Or’s DOE Used in Cancer Research

Scientists from the University of Wisconsin-Madison present an application utilizing Holo/Or’s diffractive beam splitter 2×2 (MS-724-1-Y-A) for parallel MPE fabrication of scaffolds. This mimics the ECM of native tissues. Cell biological investigations can now occur at speeds several times faster than by single point scanning methods. To read the paper, entitled “Parallel multiphoton excited fabrication of tissue … Continue reading

Microlens Arrays

Introduction A microlens array (MLA) is an optical component that consists of a set of micron-scale lenses, arranged and “packed“ together on a single supporting substrate. MLAs are used in many photonics-based devices for various applications. Each of the microlenses in the array is a plano-convex refractive lens, operating under the standard geometrical optics laws … Continue reading
