OptoLED Lite

• Fluorescence microscopy
• Brightfield and phase Contrast
• Diferential Interference Contrast

Product Description

In common with our OptoLED, the Lite version has a dual-channel modular design with a wide range of wavelengths and couplings to all popular research microscopes. Although it lacks the feedback control, sub-microsecond modulation and overdrive functionality of the OptoLED, it supports the same range of power LED emitters. Independent Intensity and shuttering of both channels is integrated using remote panel controls or from a PC via digital and / or analog control lines. We can also supply a simple USB controller for most commercial and open source software.

Available Wavelengths

Wavelength Options

The range of wavelengths available from ultra-bright LEDs covers the absorbance peaks of most fluorescence indicators. The table below shows the standard range, however we can also source more specialist devices (download information sheet). Please contact Cairn for recommendations on the best LEDs and filters for your experiments.

OptoLED Available Wavelengths

In response to feedback from our customers, the OptoLED Lite has been re-engineered to make it easier to use and to better meet the needs of those researchers who don’t require the full functionality of our OptoLED. The Lite version has been modified from a single to dual channel controller which allows users to operate at two different wavelengths or to use one LED for brightfield and the second for fluorescence.

The second alteration involved moving the most commonly used controls to a remote slider unit for improved usability.

In summary, if the control voltage is modulated, the output from the LED can be changed within a few microseconds. The high stability ‘instantaneous’ vibration-free switching and intensity modulation are other key benefits in a wide range of applications such as combined imaging and electrophysiology. The facility to ‘gate’ the light source directly from the camera and thus only expose the specimen whilst the camera is integrating helps to reduce photo-bleaching and also prevents bleed-through during frame readout.

LED head upgrade

With LED technology constantly improving we would like to remind existing customers that we are able to upgrade your current LED heads for a small charge of £100 each.

The way in which our LED heads are designed means they are readily interchangable so if returned to us we can upgrade in a very short period of time.
