Full Color Brightfield and Optional Phase Contrast
Request a Quote!

The LS420 Microscope (Lumascope) provides full color brightfield imaging at low cost for a wide variety of applications. LS Microscopes visualize and capture high resolution images comparable to those from traditional, high-cost microscopes. The LS420 utilizes advanced optical engineering and a CMOS sensor to provide near diffraction-limited (theoretical maximum) resolution. Powered only by its USB computer connection, the LS420 easily records your photos, time-lapse series, and 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 LS420 is the new upgraded version in the Etaluma LS400-Series. Its deck includes the bracket for the optional Phase Contrast Accessory and also the accessible deck design.
