Why EVOS® Cell Imaging Systems?

An EVOS® system is a must-have in your lab for cell imaging—whether you’re capturing images for publication, teaching, or research. From cell culture to complex protein analysis to multichannel fluorescence imaging, EVOS® cell imaging systems help you perform a variety of routine and specialty applications. Our proprietary LED light cube technology minimizes photobleaching, offers >50,000 hours of LED illumination, and permits precise intensity adjustments—with no darkroom and no consumables costs.

Generate publication-quality images

In today’s competitive scientific environment, generating publication-quality images is critical to your success. To help ensure that you get the publication-quality images you need, EVOS® systems give you top-of-the-line imaging components, including:

  • High-quality cameras and optics to capture high-resolution images
  • LED illumination to produce superior signal-to-noise ratios
  • Easy-to-use image capture and processing software for ready-to-publish images

The power of LED illumination

  All 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.
  • Shorter light path enables better detection of fluorescent signals
  • Continuous illumination gives consistent results
  • >50,000-hour bulb lifetime lowers your laboratory costs
  • Adjustable light intensity reduces photobleaching

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.

Constant illumination, consistent results

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.

Lower long-term maintenance costs using LED bulbs


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 a 70–75% savings in the overall upkeep of your instrument.

Higher transmission efficiencies with hard-coated filters

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 compared to 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.
