Here's a handy tool for eye care practitioners! Use our Sphere Spectacle Conversion Calculator* to easily convert a patient's eyeglasses prescription to the corresponding contact lens parameters and use your expertise to make further refinements. Refer to our Toric or Multifocal calculators for other prescriptions. Currently there are many online CCTV lens calculators for web browsers. Such online tools can help to calculate lens focal length, field of view and even pixel density: Yet, the most comprehensive ones are made as a PC software and one such example is our graphical lens calculator / CCTV design tool called IP Video System Design Tool. OptiCampus Online Optical Continuing Education. Select One of the Following optical Calculators. These are precision calculation tools for common optical and dispensing applications. This calculator combines a spherical GP lens design nomogram developed by Dr. Ed Bennett with a GP toric lens calculator developed by Dr. Tom Quinn. This combined calculator was made possible via the assistance of Dr. Todd Zarwell of EyeDock.com. This is a dynamic empirical method of determining GP spherical lens power, base curve radius, …
In optics, a thin lens is a lens with a thickness that is negligible compared to the radii of From Wikipedia, the free encyclopedia. Jump to navigation The focal length, f, of a lens in air is given by the lensmaker's equation: 1 f = ( n − 1 ) [ 1 R 1
