Abstract: This invention provides for a magnification system (10) and a method of construction. The magnification system (10) includes at least a first lens (3) and a second lens (5) lying on a common central lens axis line with an object (1) to be magnified being placed on one side of both of the first lens (3) and the second lens (5). The first lens (3) is constructed in a manner to have a first lens focal length greater than the first lens object distance for forming a first lens virtual image (4). The second lens (5) has a second lens focal length which is greater than the focal length of the first lens (3) to form a second lens virtual image (7) having a greater magnitude than the first lens virtual image formed. Through a recursive image nesting method, additional lens groupings may be added to a basic lens set to increase the magnification while minimizing optical distortions of a previous lens grouping.

Abstract: A lens magnification system is provided for booklets, such as restaurant menus, to enable persons having impaired vision or persons in an environment of poor light to magnify the print or other images of the booklet to the extent that it becomes easily readable.

Abstract: A method and apparatus for measuring hair in a predefined area of skin. The method addresses the preparation of the skin and the device for counting the hairs in a defined area. The apparatus contains an optical magnifying lens, a housing for the lens and an aperture of known surface area in order to calculate the density of the hair in the portion of skin under measurement. When the method or apparatus are used, the end result will be a density measurement of hair per unit area. When this measurement is compared with similar measurements in the same area from a previous time or from a different area at the same time, a diagnosis of whether hair loss is occurring can be made with considerable accuracy. Similar applications can be made in areas where treatment suggests that hair loss has ceased or reversed through some intervention.

Abstract: A viewing device for installation on a wall or door includes a housing projecting from the front surface of the door and defining a plurality of surveillance ports disposed axially, and non-axially relative to the axis of the housing. By means of a knob extending outwardly from the rear door surface and defining a viewing port axially aligned with the axial surveillance port, the user is able to move a mirror between a first orientation intersecting the housing axis at an acute angle and a second orientation parallel to and spaced from the housing axis. Rotation of the knob relative to the housing causes rotation and pivoting of the mirror so that, when the mirror is in the first orientation, a line of sight is defined at different times from the viewing port through each of the non-axial surveillance ports via the mirror and, when the mirror is in the second orientation, a line of sight is defined from the viewing port directly through the axial surveillance port.

Abstract: A two lens stand magnifier having variable degrees of magnification of an object at a constant distance from an observer is disclosed. A permanently mounted plus lens and a movably mounted minus lens are arranged on a stand such that the plus lens is a constant distance away from the object to be magnified. As the minus lens is moved relative to the positive lens, magnification of an object located on the opposite side of the plus lens from the minus lens varies while the image stays substantially in focus at the constant distance from the observer. Defocus of the image during movement is avoided by the choice of the lens powers as well as the spacing of the range of movement of the minus lens relative to the plus lens.
