OptoLED LED Fluorescent Illuminators – Cairn Research

The Cairn OptoLED source offers exceptional intensity stability and instant vibration-free control, ideal for sensitive experiments in cell imaging and electrophysiology.
Thanks to closed-loop control, it guarantees constant intensity over the short and long term, overcoming the limitations of alternative sources.

Its modular system, compatible with fibres, epillumination and UV/white LEDs, is ideally suited to optogenetics, photodecommissioning and multichannel fluorescence microscopy.
Fast modulation, secure power boost (up to 5 A) and direct synchronisation with cameras make it an advanced solution for biomedical research.

Characteristics of the OptoLED – Cairn Research

Instant switching (sub-microsecond), vibration-free
High luminous intensity, overmodulation possible up to 5 A
Short- and long-term intensity stability with closed-loop control
Rapid modulation for high-speed studies (calcium, electrophysiology)
Synchronisation with the camera to avoid photodamage and artefacts
No ND filter required thanks to variable intensity
Minimal infrared emission – reduces heat build-up
Scalable modular system: multiple LEDs, fibres, configurations possible
UV/white LED for illumination and uncaging
