Oct 2003Tower Optical Corp.Request Info
Tower Optical Corp. has released a line of achromatic wave plates that cover the 465- to 610-nm, 700- to 1000-nm and 1200- to 1650-nm wavelengths, ranging from the visible to the IR. They have a clear aperture of 11.5 mm and are available, in all ranges, for both λ/4- and λ/2 retardation. Air-spaced versions are standard, and a cemented version is available by special order. The company says that the wave plates, fashioned out of crystal quartz and magnesium fluoride, maintain nearly constant retardation over the covered spectral range.
