The FluoLED product range from Olympus introduces additional flexibility to fluorescence microscopy. Each model is designed to fit to the Olympus CX microscopes. Further extending this application area is the ability to power the LEDs by battery or even solar power ensuring that fluorescence microscopy can be conducted in field where samples are fresh. The PrecisExcite is a LED fluorescence light source, featuring the specially developed LED array modules (LAMs) as well as a cooling system. The LAMs are interchangeable and enable up to three different wavelengths to be used at once.
