Here is your first look at the editorial content for the upcoming May/June issue of BioPhotonics.Quantum Cascade Lasers for IR Spectroscopy Trailblazers in analytical science have long demanded spectroscopic imaging information with rapid time-to-results. Quantum Cascade Laser Infrared (QCL-IR) Microscopy is a novel approach to chemical imaging that uses the high brightness of QCLs to acquire micro-spectroscopic imaging data at higher speeds than is possible with incoherent light sources (used in FT-IR microscopes for example). QCL-IR microscopes are now enabling rapid hyperspectral imaging and, in some cases, video-rate imaging at discrete IR illumination wavelengths.
