Enhancing Two-Photon Microscopy

Two-photon microscopy has many advantages over conventional microscopy including: minimal photo-bleaching effect and sample damage, higher imaging depth of live cells, higher excitation efficiency, and simultaneous excitation of multiple fluorophores with the promotion of autofluorescence. Ultrashort (<10 fs) pulses enhance the two-photon microscopy technique. The peak power for a given average output is much higher … Continue reading

Name a Cost-Efficient Open-Source Laser Engine for Microscopy

Researchers from EBML in Heidelberg and University of Jena recently published a paper entitled: “A cost-efficient open source laser engine for microscopy”. The abstract of this paper states: “Scientific-grade lasers are costly components of modern microscopes. For high-power applications, such as single-molecule localization microscopy, their price can become prohibitive. Here, we present an open-source high-power laser … Continue reading

Holo/Or Transforms Multi-Mode Laser Beams into Narrow Annular Shapes

Transforming the beam of a highly multi-mode laser into a narrow annular shape with almost single mode diffraction-limited ring width is a potentially useful technique for certain material processing applications, such as drilling and cutting. Holo/Or has published an experimental demonstration of our unique diffractive method of doing this transformation. To read a new article … Continue reading

SCI from Apre Measures Optical Domes Faster and More Accurately

Dome optics are the last component in a growing number of imaging and guidance applications. Domes protect the imaging optics from the surrounding environment without degrading optical performance. Therefore the dome’s transmitted wavefront quality is important to control since it directly influences the final image quality. Dome applications include: Underwater cameras Submersibles for robotic and manned … Continue reading
