Request InfoOSI Optoelectronics Inc.Quadrant silicon photodiodes operate between 350 and 1100 nm. Used for backscatter-reflectivity measurements, the annular package design features 200 µm laser-cut hole on the chip and a header that enables coupling a fiber from the back of the detector. This ensures the detector’s sensing area is always normal to the direction of light, reducing the need for angular compensation during backscatter measurements.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 12/22/202196Board Camera MezzaninesA series of 96Boards camera mezzanines from Arrow Electronics Inc. enable fast prototyping and development of traditional and AI-enabled vision solutions.

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 HandbookDetectors: Guideposts on the Road to Selection: Choosing a detector requires evaluating many operating parameters and desired outcomes. This introduction provides a series of guideposts that will help lead the way to the right one.Any number of medical, industrial, and analytical applications requires the detection of light. Chemiluminescence, bioluminescence, fluorescence, and atomic absorption are just a few, and all require...Photonics HandbookPhotometry: The Answer to How Light Is Perceived: Simply put, photometry is the measurement of visible light based on the response of the average human observer. How that definition translates into technically correct quantification methods is the focus of this article.That portion of the spectrum that the eye can see — and its rainbow of colors — is rather small, covering approximately 360 to 830 nm. What colors we perceive depends on wavelength, while...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.
