EVOS now offers newly updated and optimized light cubes that feature improved opto-mechanical design and spectrally optimized optical components. The new design results in superior illumination uniformity across the field of view and maximizes signal-to-background ratios even with dim samples. The cubes are backward compatible with the legacy EVOS light cubes described above, and can also be used with the Invitrogen Countess II FL Automated Cell Counter for expanded interchangeability.
Optimized EVOS Light Cubes provide best-in-class multi-field of view stitching performance.

Individual panels (right) show the channels that make up the composite.
The new EVOS light cubes provide best-in-class spectral fidelity across channels, eliminating undesired bleedthrough.

HeLa cells were labeled with a single bright Phalloidin conjugate, fluorophore indicated on left, and imaged using DAPI, GFP, RFP, and Cy5 EVOS Optimized Light Cubes. As shown in the individual panels, even with bright fluorophores and abundant labels such Alexa Fluor Plus labeled actin cytoskeleton, each light cube shows signal only from its intended target with no bleedthrough, due to the spectral optimizations of the LED excitation sources and filters used in Optimized EVOS Light Cubes.

All of the EVOS fluorescence cell imaging systems utilize LED light sources. That means you get high-intensity output over a short light path for the most efficient fluorophore excitation.
Revolutionary light path
By placing the LED light cube as close as possible to the objective turret, the number of optical elements in the light path is minimized. High-intensity illumination over a short light path increases the efficiency of fluorophore excitation, providing better detection of weak fluorescent signals.
Continuous light intensity
Mercury arc lamps can decrease in intensity by 50% in the first 100 hours of operation—plus, images acquired in different sessions cannot be quantitatively compared using mercury illumination without complicated calibrations. Because EVOS systems have continuous light cube intensity, users can rely on consistent illumination and can compare results quantitatively from images acquired on different days.
Less expensive to own and maintain
The LED bulbs on the EVOS systems are rated for >50,000 hours (~17 years), compared to 300 hours for a typical mercury bulb (and 1,500 hours for a metal halide bulb). That means significant savings in the overall upkeep of your instrument.
Hard-coated filter sets are more expensive, but they have sharper edges and significantly higher transmission efficiencies that typically result in >25% more light transmission than traditional soft-coated filters. With the EVOS system’s hard-coated filter sets, your light cubes cost less over time. Plus, you will have brighter fluorescence, higher transmission efficiencies, the ability to detect faint fluorescence signals, and better signal-to-noise ratios.
TRANSMISSION EFFICIENCY COMPARISON
Superior transmission efficiencies are observed using hard-coated filters on the EVOS instruments, compared to soft-coated filters. Excitation filter (purple), emission filter (red), dichroic mirror (green); Alexa Fluor 488 excitation (blue), Alexa Fluor 488 emission (pink).
