"Design and Fabrication of a Wide Angle 3x Array Telescope

Principal Investigator: Milton Katz, O.D., F.A.A.O. Professor, Optics, Department of Vision Sciences, College of Optometry, State University of New York

Abstract:

Background: The prescription of optical devices is probably the most common intervention to improve the low vision patient's visual functioning. Telescopes provide magnification for viewing distant objects. They enable the user to independently travel and even, in some cases, to drive a car. However, magnification results in small fields of view (FOV). Telescopes with a magnification of 2.9x have a mean FOV of 3.9 degrees, or 16 inches at 20 feet.

Aim: To develop a telescope with a 3x magnification with a field of view that is four times greater than the current 3.9 degrees.

Method: Using a design similar to that used for the 2x telescope (MKAT) created by Dr. Katz, lenses and prisms will be designed, mounted and assembled.

Expected Results: Design of a telescope with the ability to magnify 3x while allowing the user to have a FOV of greater than 16 degrees at 20 feet.
