Fluorescence has long been used to study bioluminescent organisms, the folding of proteins, and in the identification of minerals. With the explosion of fluorescent dyes & tags in the last 50 years and development of techniques like FRET, fluorescence has become a technique unto its own for the study of biological structure, morphology, and interactions. It has revolutionized cytometry, histology, and immunology – making the ability to see specific fluorescent tags a critical technique for research and diagnosis. Fluorescence has even found a place in authentication and quality control.
The challenge in this field is one of sensitivity – microscopes and PMT-based systems have dominated detection, limiting the use of many fluorescent techniques to the lab. Our new generation of fluorescence spectrometers & systems change all that by approaching the sensitivity and spectral resolution of much larger benchtop instruments in a compact, portable footprint.
Eliminate fiber coupling losses and maximize fluorescence collection using a cuvette holder that mates directly to the spectrometer. Designed to fill the full low f-number apertures of our WP VIS and WP VIS-NIR spectrometers, this cuvette holder offers the convenience of fiber coupling your illumination source at 90° or 180° to the spectrometer port. Filter holders allow use of stock filters to select your excitation band and exclude scattered light from the detection path, while an anodized cap blocks ambient light. The cuvette holder also comes with an optional SMA fiber port adaptor to allow for use with an existing fiber-coupled spectrometer or setup.
Our team has worked with leading research groups and companies in biotech, medicine, agriculture, and authentication, and can offer you the expertise needed to make your R&D or product development successful.
