Use the LS620 to visualize and capture high resolution fluorescence images comparable to those from traditional, high-cost microscopes. LS Microscopes utilize LED light sources, Semrock filters, advanced optical engineering, and CMOS sensors to provide near diffraction-limited (theoretical maximum) resolution. Powered only by its USB connection, the LS620 easily records your photos, time-lapse series, and live videos directly to your computer. And its compact size enables working in challenging locations, including inside incubators, biological safety cabinets, and environmental control workstations. The LS620 provides blue, green and red fluorescence imaging at low cost for a wide variety of applications!Features and Benefits

Features and Benefits:

  • Fully functioning microscope empowers users to visualize cells from slides, microplates, flasks, or dishes
  • Versatile and compact design permits use inside cell culture incubators, tissue culture hoods, and environmental workstations
  • Robust software enables time-lapse studies over seconds, minutes, hours, or days
  • Modern LED and optical design lowers cost and eliminates cumbersome, difficult to maintain laser-driven and arc lamp systems
  • Power and control via USB connection facilitates rapid set up and easy use
  • Custom optimized filter set detects a range of blue, green and red fluorophores, including BFP, DAPI, FITC, Fluo-4, GFP, and mCherry
  • Advanced optics provide excellent resolution in ambient lighting conditions
  • Objective compatibility with standard lenses allows use of your own objectives
  • Optional Phase Contrast Accessory enhances visualization of unstained samples
  • The LS620 is the most powerful digital microscope offered anywhere at this price. Like the earlier LS600, it utilizes a Semrock Brightline® Pinkel filter set optimized for 405 nm, 488 nm, and 594 nm LED light sources. The 5-filter set is comprised of 3 exciting filters, 1 triple-band emitting filter, and 1 beam-splitting filter. The LS620 also contains the same CMOS sensor as the LS600 that is larger than the sensor used in LS520 and LS420.
