Where do I get the free version of the LSM software?
The LSM Image Browser is available free at the Zeiss website. With this software you can open your .lsm images and save them as other formats. Follow this link or go to Zeiss.com and navigate to Products: Microscopes -> Confocal -> Download Software -> scroll down to Laser Scanning Microscopy and choose ZEN 2008 LE or LSM Image Browser.
