Commack, NY [July 2026] — ACCU-SCOPE Inc. is pleased to announce the introduction of the ACCU-fluor ST LED Fluorescence Illuminator, a compact, all-in-one fluorescence illumination system purpose-built for stereo microscopes with a parallel (Common Main Objective/Galilean) optical design. The ACCU-fluor ST makes fluorescence observation of whole organisms, embryos, and intact tissues accessible and affordable for developmental biology and model organism research laboratories.
Stereo microscopes are the instrument of choice when researchers need to observe fluorescent signals at the tissue level or organismal scale — across an entire zebrafish embryo, a fruit fly larva, a C. elegans worm, or a whole-mount tissue preparation. Until now, adding quality fluorescence capability to a stereo microscope required costly, complex illumination systems. The ACCU-fluor ST changes that.
“Fluorescence imaging at the organismal scale is fundamental to modern developmental biology and genetics research, and we’ve long wanted to bring the same simplicity and value we achieved with our ACCU-fluor illuminator to the stereo microscope bench,” said Brian Taub, CEO of ACCU-SCOPE. “The ACCU-fluor ST does exactly that — it’s a complete, ready-to-use fluorescence solution that installs in minutes and works with the stereo microscopes researchers already have in their labs.”
The ACCU-fluor ST houses the LED light source and fluorescence filter cubes in a single compact unit, with no external power supplies, fiber optic light guides, or additional bench footprint required. A single knob simultaneously moves both the light source and filter cube, making channel switching fast and effortless. A digital front-panel display shows the active channel and light intensity, with a per-channel memory function that retains the user’s preferred intensity settings. The illuminator is completely mercury-free, with LEDs rated for years of maintenance-free use.
ACCU-fluor ST is available in dual and triple-channel configurations, with excitation options spanning violet (for DAPI/Hoechst), blue (for GFP/FITC/Alexa Fluor 488), green (for TRITC/Cy3/dsRed), and yellow (for mCherry/Texas Red) — supporting the fluorophores most widely used in model organism and developmental biology research.
The ACCU-fluor ST is compatible with stereo microscopes from ACCU-SCOPE, UNITRON, Evident (Olympus), Leica, and Zeiss that utilize a parallel (CMO/Galilean) optical design.
