These single glass dispersion compensation blocks are designed for use with our LSM scan lenses. The glass type and thickness were chosen so that the dispersion matches the first and second order dispersion of the LSM scan lenses. The dispersion-compensating block is meant to be placed in the reference arm before the mirror, while the scan lens is placed in the sample arm. This configuration creates an identical amount of dispersion in each leg of the interferometer. Our dispersion compensators are mounted in either an SM1-threaded lens tube or SM05-threaded lens tube engraved with the item #.
