Request InfoAndover CorporationSteep-edge longpass filters from Andover Corp. feature magnetron-sputtered hard oxide coatings. The devices yield deep rejection to >OD 4 and a sharp transition slope of 1 percent to very high transmission. The coatings are deposited on precision-polished fused silica substrates and do not employ any absorbing filter glass, making them suitable for high-temperature applications.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2022 IssueMicropump LasersI-Temp micro-pump lasers from Coherent Corp. are designed for ambient temperature operation in broadband optical access networks.

A typical optical delay line consists of a retroreflector or folding mirrors on...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 HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery, and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookOptical Components: Finding Your Way Through the Maze: Optical components fall into two basic groups: transmissives and reflectives. Transmissives include lenses, filters, windows, optical flats, prisms, polarizers, beamsplitters, wave plates, and fiber optics; reflectives include mirrors and retroreflectors. The performance of all may be enhanced with certain substrates and thin film coatings.Lenses come in a variety of shapes, sizes and materials. They can be made of a single piece of glass or have multiple elements; their surfaces can be spherical, aspheric or cylindrical; they can be...WHITEPAPERSPhotonics.com 8/1/2023Hand Cleaning of Small OpticsA great "How-to" for cleaning optics.
