Single Line Focusing Objectives

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.
