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 HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. 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 HandbookInfrared Spectral Selection: It Begins with the Detector: An IR imaging system employing a narrow spectral band brings hidden images to light, broadening IR imaging’s applications.Spectral selection is a powerful tool that enhances conventional imaging tremendously.
