Request InfoMKS/NewportNewport Corp. has announced the availability of a chromatic confocal height sensor for use with its MRSI dispense systems. The sensor allows measurement on a single axis, providing access to deep cavities, confined spaces and areas that are close to walls and other obstructions. This tool is suitable for radio-frequency and microwave packages, where measurement using traditional reflective laser height-sensing techniques is difficult. An LED light source with a sensor spot size of 50 μm in diameter provides nanoresolution that is nearly target-independent. The device allows accurate...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2020 IssueDeep-UV LEDsThe DUV255-SD353 series of deep-UV, high-power LEDs from Roithner Lasertechnik GmbH is based on aluminium gallium nitride.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookMicroscopy Illumination: Considering Nonlaser Light Sources: Metal halide and LED light sources are changing the illumination landscape in microscopy. Brighter, easier to use and growing in application, they are driving new options in fluorescence, conventional bright-field and other contrast techniques.As recently as five years ago, shopping for a microscope light source was fairly straightforward. For routine applications, it was tungsten halogen, typically 100 W, while for fluorescence, it was an...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 275 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...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.
