Like other products in the OptoLED family, the OptoFlash is LED-based with coupling options for most microscopes. The option to launch the OptoFlash into a fiber optic with the diameter ranging from 100um to 1mm is also available. The OptoFlash is unique in that it has been optimized for short-term intense illumination. This makes it particularly suitable for the photoactivation of “caged” neurotransmitters or other compounds, and for the application of channel rhodopsin activation.

CairnTwinLED Light Source
Ratiometric calcium imaging with LEDs can work extremely well, but, due to the relatively narrow bandwidths and spectral variations of individual LEDs, it does require attention to detail. The TwinLED head works directly with our OptoLED controller and makes the process simple, as we take care of the LED selection, intensity regulation and bespoke optics to make your experiments work with the best possible signal-to-noise.
• Preconfigured & compact
• Near perfect stability
• Full LED ratiometric illuminator(0 reviews)
CairnAura Phase Contrast Illuminator
The Aura is a ring-light of LEDs that replaces the microscope condenser for phase contrast imaging on an inverted microscope.
Allows true Zernike phase contrast with extra working space around the sample
Excellent for complex experiments in electrophysiology, live cell imaging, and multi-modal time lapse
Provides large working area above the sample for electrophysiology and microfluidic equipment
Working distance of up to 220mm
