Fluorescence Microscopy: Understanding Fluorophores

Fluorescence microscopy is a method of observing photo-emissive spectra from samples, and acquiring fluorescent signals that are roughly one million times weaker than the incident or one thousand times weaker than the scattered light. Observing the fluorescence of an analyte requires a sensitive array comprising an incident light source and robust optical filters with exacting […]

Hyperspectral Imaging Applications

Hyperspectral imaging is the process of photographically acquiring data from across the electromagnetic spectrum, with the aim of obtaining spectral information in each pixel of a captured image. This detailed technique uses multiple imaging methodologies to photograph a scene across the spectral range in many contiguous spectral bands. Hyperspectral imaging spectrometers cover wavelengths beyond the […]
