LS620: Enhanced Fluorescence Imaging with Blue, Green, and Red Channels

Experience the power of LS620, a digital microscope designed to deliver high-resolution fluorescence images comparable to traditional, high-cost microscopes. This versatile tool employs LED light sources, Semrock filters, advanced optical engineering, and CMOS sensors to achieve near diffraction-limited resolution. Powered solely through its USB connection, the LS620 effortlessly captures photos, time-lapse series, and live videos directly to your computer. Its compact size allows operation in challenging environments, such as inside incubators, biological safety cabinets, and environmental workstations.

LS620: Unmatched Power at an Unbeatable Price

The LS620 stands out as the most powerful digital microscope available in its price range. Building on the success of its predecessor, the 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 includes 3 exciting filters, 1 triple-band emitting filter, and 1 beam-splitting filter. The LS620 boasts the same larger CMOS sensor as the LS600, surpassing the sensors used in LS520 and LS420.

What's Included with the LS620

The LS620 comes equipped with a new black anodized deck featuring a tab for mounting the Phase Contrast Accessory. The accessible deck includes a removable insert for easy access to the objective, allowing quick switching. The underside of the deck has two tapped holes for mounting the optional Manual XY Stage. The package includes a USB power/communication cable, fluorescence shroud, and an external power supply/cord with a country-appropriate plug for situations requiring brighter lighting (typically not needed).

Lumaview Software Control

The LS620 is controlled by the Lumaview software, available for free download from the Etaluma website under Resources/Downloads. Objectives are sold separately and can be found under Products/Objectives.
