title: Design of a holographic lens for the infrared.
abstract: Techniques are described for the construction of a holographic lens for focusing a collimated beam to a point. The lens is constructed in the visible for use in the near infrared. A major problem is to eliminate aberrations that result from the shift between the wavelength of construction and of use.
