All Special Optics Single Line Focusing Objectives are
corrected for astigmatism and coma over the specified
spectral range. However, they are not corrected for
chromatic aberrations. These lenses are well suited
for use with Solid State and Gas Lasers where only one
wavelength is in use, or when shifts in focal length can be tolerated as the
wavelength must be specified when
ordering to indicate the appropriate anti-reflection coatings.
