A compact, single-wavelength LED illuminator built for routine fluorescence screening, diagnostic work and electrophysiology where only one excitation colour is needed. Users pick from 20 available LED wavelengths (365-770nm) at time of order, with a handheld control pod offering instant on/off and 1% step irradiance control, plus TTL triggering (~150μs). Ships as direct-fit, liquid-light-guide, or fibre-coupled.
