GLIM-Zeiss-HamGradient Light Interference Microscopy (GLIM), attached to a Zeiss Axio Observer microscope with DIC illumination. (Microscope sold separately.)

The Gradient Light Interference Microscopy (“GLIM”) imaging system comes in two different versions: GLIM Basic and GLIM Pro. GLIM Basic works with manual microscope stands and is suitable for single-location, single-focus time-lapse imaging. GLIM Pro interfaces with motorized microscope stands to yield fully automated high-throughput, multichannel acquisition. It is suitable for more complicated projects that require 2D and 3D scanning, multi-channel experiments and fast dynamics measurement. At full speed, GLIM Pro generates more than 1TB of data per hour. Phi Optics offers storage server solutions for efficient management of this high volume of data. Please contact us with inquiries.
