Web site

CoolLed has launched a revised Web site to focus on the application of its precisExcite LED light source for fluorescence microscopy. The resource explains the benefits of LED excitation of fluorophores, which include extended lifetime, ease of use and better control. It notes that, with the source, there is no need for neutral density filters, no need to align the lamp, no need to record lamp usage and no degradation of performance over time. It includes downloadable application notes on such topics as users’ experiences with the light source for live-cell imaging. Related time-lapse videos show epithelial cells derived from the lining of the human airway. The portal also includes sections on news, filters, endorsements and distributors, along with a photo gallery and an explanation of fluorescence microscopy.

There are 277 suppliers of Microscopy in the Photonics Marketplace.

Glossary

fluorescence microscopy: Fluorescence microscopy is a specialized optical imaging technique used in biology, chemistry, and materials science to visualize and study specimens that exhibit fluorescence. Fluorescence is the phenomenon where a substance absorbs light at one wavelength and emits light at a longer wavelength. In fluorescence microscopy, fluorescent dyes or proteins are used to label specific structures or molecules within a sample. The basic principles of fluorescence microscopy involve illuminating the...
