We either manufacture locally or purchase from the microscope manufacturer cubes that are designed for most of the currently used fluorescence microscopes. Chroma produces many standard filter sets and a few custom designs for Leica Microsystems. Both Carl Zeiss and Nikon Corp. offer extensive selections of our filter sets for their new microscope models. Olympus dealers and distributors have access to our products through Olympus America and directly from us. We encourage you to work with your local dealer or representative when purchasing filter sets manufactured by us.
