A Day in the Life of a Fluorophore
Fluorophores are a bit like colourful employees working the world’s most demanding shift pattern, who just need a bit of gentle encouragement to get them through their day…
Coming Soon: CoolLED Optogenetics Light Source
Neuroscience researchers want dependable, flexible and accurate illumination for both imaging and stimulation. Our new optogenetics LED light source is being designed with those needs in mind
From Mercury to Modern LEDs: A Turning Point for Fluorescence Microscopy
With the ban in Feb 2027 in mind, it’s only fair to give credit where it’s due: Mercury and metal-halide bulbs got fluorescence microscopy this far. LEDs will take it the rest of the way
How Fluorescence Helps Us Understand the Immune System
Whether the work involves basic immune behaviour, developing new immunotherapies or studying inflammation – consistent illumination is one of those quiet but essential ingredients that keeps the data trustworthy
Why Light Stability Matters in Long Time-Lapse Experiments
Biology is variable enough. You don’t want the light source adding its own version of “plot twists”. You need consistent, fast, stable illumination every single time
Top 5 Tips for Retrofitting LED Illumination into Existing Microscopes
If your lab still relies on mercury or metal-halide lamps for fluorescence microscopy, the countdown is officially on – but the good news is you don’t need to replace your entire microscope to go mercury-free…
