In the past, a thin-film design software was used to help develop the coating, but the real challenge was in actually replicating the design thickness and the material indexes inside the coating chamber without any errors.

As the U.S. continues to increase its security at border crossings, airports, and other points of entry, biometrics will play an important role. Fingerprints and other direct contact means will become final identifiers of persons.
Datasheets can be misleading, so how do you know what you are really buying? To help optical designers and engineers view optical datasheets more critically and ask the right questions of lens providers, this article discusses key datasheet parameters.
An incorrect or poorly lit subject affects the image, regardless of camera system quality. Therefore, the illumination source is just as important as the camera's resolution and sensitivity. See how a laser can be used for illumination in these four high-speed imaging application examples.
OSI Optoelectronics offers a range of high-speed silicon photodiode detectors optimized at 800 nm band. These small and large active area detectors feature a fast rise time for high-bandwidth applications up to 1.25 GHz. They are available in flat window or micro-lens window TO18 models.
