Fluorescence Microscopy

Florochrome Data Tables:
Olympus Cube Data

The data tables below contain reference information on fluorescence cubes offered by Olympus America, Inc. to support their microscopes. The codes for the excitation columns in Tables 2 and 4 and the cube code column in Table 3 are listed in Table 1. Table 2 is a listing of examples of cubes provided for U-URA microscopes. The authors wish to caution that we believe this data to be accurate, but it should always be verified by authorized Olympus representatives.

Table 3

Table 4 is a cross-reference for Olympus U-URA cubes to Olympus BH-2, Vanox-3, and IMT-2 cubes. It is advisable to consult the manufacturer's wavelength/transmission curve diagrams for exciter filters, dichroic mirrors and barrier filters to determine how they match the fluorochrome being used. The cube names and nanometer numbers refer to the Olympus U-URA cubes; the figures in parentheses refer to filters still current for BH-2, Vanox 3, and IMT-2 fluorescent cubes.
