CoolLED pE-800 LED widefield illumination system

Featuring eight individually controllable LEDs and ultrafast TTL switching, CoolLED’s pE-800 is a widefield illumination system that delivers high-quality data. Versatile and intuitive, the product features liquid light guide delivery, designed to make next-generation LED illumination accessible to all.

Eight individual analog inputs allow irradiance to be controlled from 0–100% for each channel via analog signal (0–10 V), which is suitable for electrophysiology and optogenetics applications. The system features <7 µs TTL triggering for live cell imaging. Capturing dynamic events is possible with high temporal resolution and even without software, due to precise hardware synchronisation via TTL input for each channel and compatibility with the pE-6501-8 (USB-controlled TTL conversion kit).

The ability to fit inline excitation filters capitalises on TTL trigger speeds, as single-band excitation filters can be installed for each channel. When used alongside multiband filters, eg, in a Pinkel configuration, this removes the need for external filter wheels and overcomes the latency restrictions of mechanical movement.
