Lambda Research Corporation has been providing opto-mechanical design environments for over 30 years. Deeply rooted in the optics industry, with a university program that supports the design community, our experience speaks for itself. Our award-winning software has helped designers shape the world around us for the better, from LED lighting to medical devices to complex space telescopes. Our intuitive user experience and world-class technical support set us apart from the rest. We make optical design fun!

In optics, the distance from the middle of the lens to its focal point. Light rays run in parallel to one another, while lenses distort light rays: a convex lens (the type that is thicker in the centre than at the edges) brings them closer together and a concave lens (the type that is thinner in the centre) forces them apart. Cameras use convex lenses to bring the light rays together to a point where they converge and the image is in focus: this is where the film or light sensitive diode goes. The more convex (or thicker) the lens, the more severely the light rays are bent and the shorter the focal length (conversely, the thinner the lens the longer the focal length). Different focal lengths create different kinds of image effects. Lenses with very short focal lengths (or wide angle lenses) allow more of the picture to be seen and emphasize foreground elements, whereas lenses with very long focal lengths (or telephoto lenses) allow less of the picture to be seen and emphasize background elements which appear to be magnified. These different effects are dramatically illustrated by a technique used in feature films called a Hitchcock zoom, where the camera tracks out at the same time as it zooms in (or vice versa), an effect used in the film Vertigo (1958).

Opticalsimulationsoftware

"TracePro’s intuitive 3D user interface saves us time and money. TracePro allows us to quickly generate accurate optical simulations from our SOLIDWORKS and CREO CAD models. The 3D visual nature of TracePro allows us to easily verify our geometry. We routinely use TracePro for design and analysis of illumination systems including optical instruments, LED optics, light guides, tissue optics, LIDAR and UV Disinfection systems."Fred Bushroe,President, INOV Inc.

Hamamatsu Avalanche Photodiodes with normal or UV-enhanced response and ideal for low-light level measurement are available at Edmund Optics.
