Download Geometric Optics 1.1.9 (Windows) – Download & Review Free

Geometric Optics is a very easy to use and fun little tool javabased app that helps users analyze how a lens casts an image of an object.

web-based application

This program requires a compatible browser to use.Additionally, it requires Java and Adobe Flash Player It needs to be installed to start normally. Once these conditions are met, the utility will run in a special HTML online file with all GUI elements rendered through a Java interface in your favorite browser.

Basically, all Geometric Optics shows you is simulated objects, lenses, and projections of objects. Users can move an object around and see how it would look with different indices of refraction and radii of curvature. An additional control panel can be seen to help users change camera and object properties.

Built for Educational Purposes

A key feature of this tool is its ability to help students of cinematography and even physics majors understand camera obscura optics and how different lens curvatures, refractive indices, and even lens diameters alter the properties of an object’s projection.

To see this graphically, the user can select or deselect the projected rays, moving the lens itself along with the projected object to all available positions. If the projection of one point is not enough, users can also enable a second point and get details on how exactly the light reaches the target screen.

After the user completes the simulation, the data can be uploaded to PhET’s official website, and interested users can access and test a free database of similar Java-based simulators.

in conclusion

Geometric Optics is a nice little app for simulating projections in a camera obscura. Users can vary lens diameter, index of refraction, index of refraction, and curvature, and can add more contextual constraints, making the program ideal for educational purposes for students.
