ABF Magnifying Tools 1.2 (Shareware, $14.95)

ABF Magnifying Tools is a set of useful graphics tools for viewing the screen area in different zooms. Each tool has its own unique behavior and usability. All tools supplement each other and allow designers and people with poor eyesight to work with computers better. The set contains:

Camera Module 3.60 (Shareware, $85)

The Camera module covers all major still film formats from 35mm to 8 x 10in/18 x 24cm. The data for 16 fixed focal length or zoom lenses can be stored. The calculations include angle of view, depth of field, hyperfocal distance, area covered, magnification, enlarging, flash, infra-red focusing, light source conversion, print perspective and time/temperature. Includes calculations for supplementary lenses and lens extension.

Cine Module 3.50 (Shareware, $85)

The Cinematography module covers all major film formats from 8mm to 70mm. The data for 16 fixed focal length or zoom lenses using T or f stops can be stored. The calculations include angle of view, depth of field, hyperfocal distance, area covered, magnification, exposure, film length/running time, light source conversion, projection. Includes provision for front nodal point compensation and calculations for supplementary lenses and lens extension.

DMControls.Lens .NET control 1.0 (Shareware, $149)

DMControls.Lens is an efficient fully customizable control easily integrated in Microsoft Visual Studio .NET that enables you to retrieve the magnification scale of screen objects. Either selected bitmap objects or selected screen regions can serve as the source for zooming. There are three modes that allow user to define zooming space: manual (no reaction to mouse), continuous (through following the mouse pointer) and Drag'n'Drop. The selected area can be copied into clipboard being enlarged or in its normal size "as it is". This efficient control gives you an opportunity to work with enlarged areas not only through the clipboard but also directly get them as a bitmap objects from DMControls.Lens by calling controls methods. Tracing of the cross-hair absolute or relative location is also available. Convenient dynamic rulers, selectable zoom factor, build-in controls meant for displaying xy mouse coordinates and a large number of other ever-useful features convey the reliability and high quality of DMControls

Gravitational Lensing 1.00 (Freeware)

Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. When light passes through the cluster from an object lying behind it, the light is bent and focused to produce an image or images of the source. The image may be magnified, distorted, or multiplied by the lens, depending upon the position of the source with respect to the lensing mass. The characteristics of the gravitationally lensed image depend upon the alignment of the observer, the lens and the background object. If the alignment is perfect, the resulting image is an Einstein Ring. With this program, one can draw images to see the effect of gravitational lensing. You can easily test the effects of several parameters by changing them and redrawing the image.

Looking Glass 1.0b2 (Commercial, $22.00)

Looking Glass is a geometric optics construction set that allows students to create and explore situations involving several objects, lenses, mirrors and images. This software takes an interactive, visual approach to physics. Looking Glass will help students develop an intuition for the effect of lenses and mirrors on light rays. Students will gain a better understanding of the physics behind the images. By creating and exploring their own lenses and mirrors with Looking Glass, students encounter many of the core concepts in optics.

ZoomAView - The Computer Magnifying Lens! 1.5 (Shareware, $24.95)

ZoomAView is a powerful, easy to use computer desktop screen magnifier for Windows. Featuring multiple zoom levels (up to 32x) within a fully moveable and sizeable lens window, ZoomAView helps you see web pages, e-mail, text documents, pictures, and more without having to strain your eyes. Choose to have the lens show exactly what's under your mouse wherever it moves, or use

ZoomMagic 2.02 (Demo, $20)

ZoomMagic is a powerful tool to magnify any portion of your screen, measure distances or capture a screen area. Targeted users are: designers and developers on the hunt for those lost pixels .. or in the need for a fast screencapture, users with visual impairments or anybody who needs to find the shortest way between A and B or quickly zoom into a screen portion. Its unique and precise technique of displaying the content of the graphiccard easily allows to measure distances or areas in the units you need (cm,inches..) or select and capture a screenarea to clipboard or file (jpg, gif, bmp..++).
