LS820 Microscope

The LS820 offers autofocus and Z-stacks.

Blue, Green, 
and Red Fluorescence with Autofocus and Z-Stacking for Time Lapse Automation

The powerful, new LS820 Microscope is the latest generation of our fully automated three-channel motorized Z model and offers the latest advances in optics, camera, and user flexibility. The LS820 provides the image quality, Z-range, illumination, and software flexibility over the manual LS620 model. Motorized focus allows autofocus and z-stacks over 14 mm with 100 nm steps. Easy-to-configure software generating user readable and editable scripts, facilitate your automated microscopy experiments. The LS820 in your incubator allows you to have a live cell imaging system that offers minimum photo toxicity and the most stable environment for long term imaging. Whether imaging flasks, dishes or slides with 3 fluorophores in a multi-day time-lapse, the LS820 offers a compact solution for walk-away automated microscopy!

Like all of Etaluma’s microscopes, the LS820 utilizes a Semrock Brightline® Pinkel filter set optimized for our 405 nm, 488 nm, and 590 nm LED light sources. The 5-filter set is comprised of 3 excitation filters, 1 triple-band dichroic, and 1 triple-band emission filter. The LS820 use a 12 bit monochrome CMOS sensor.

The new LS800 series microscopes are equipped with a low profile, multimodal illuminator that was developed in collaboration with Cairn Research Ltd (based on Aura/Aura Pro™ phase contrast illuminator, based on work by Dr Kevin Webb, Optics & Photonics Research Group, University of Nottingham: Webb, Kevin F. “Condenser‐free contrast methods for transmitted‐light microscopy.” Journal of microscopy 257.1 (2015): 8-22.
