LIVINGSTON, Scotland, Feb. 14, 2013 — Edinburgh Instruments Ltd.’s Photonics Div. has added a combined microscope and imaging camera to its FLS980 and FLS920 photoluminescence spectrometers. The microscope-camera combination enables measurement of specific points within a sample and allows imaging with monochromatic excitation/illumination.
Upright and inverted microscopes from leading manufacturers can be coupled to the spectrometers via optical fibers. Imaging is possible with wide-field excitation or in spot mode with approximately 1-μm spatial resolution. Cameras are available for the visible and near-infrared regions up to 1700 nm, and all microscopes and cameras can be retrofitted to the spectrometers.
The FLS980 and FLS920 photoluminescence spectrometers use single-photon-counting techniques for steady-state and lifetime measurements in fluorescence and phosphorescence. The spectrometer software provides full control of the microscope, including automated microscope stage scanning and data acquisition for mapping.
A choice of configurations provides measurement versatility. Spectral scanning of large areas is possible using wide-field epi-illumination, or of much smaller areas using lasers for excitation. Fluorescence and phosphorescence time-resolved measurements can also be made in wide-field or spot mode.
