Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in...Photonics HandbookLight-Emitting Diodes: A Primer: Light-emitting diodes (LEDs) are semiconductors that convert electrical energy into light energy. The color of the emitted light depends on the semiconductor material and composition, with LEDs generally classified into three wavelengths: ultraviolet, visible, and infrared.The wavelength range of commercially available LEDs with single-element output power of at least 5 mW is 360 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookWHITEPAPERSMaking Innovation Faster: 7 Lessons from Luminate on Building Effective Accelerators for Optics EntrepreneursAll entrepreneurs face obstacles moving a product from lab to launch.
