Request InfoResearch Electro-Optics Inc. (REO)REO’s new superpolished laser mirrors offer low loss and can be produced on a number of substrate materials. Their microroughness is <0.5 Å, enabling scattering loss of <5 ppm and finesse of 200,000 when incorporated into optical cavities. Ion beam-sputtered coatings, used to take advantage of the ultrasmooth surfaces, deliver reflectivities of >99.998% at any wavelength in the 450-nm to 2-μm range. The mirrors are supplied with diameters in the 6- to 101-mm range, with a flatness of λ/20 at 633 nm, 10-5 surface quality over an 80% clear aperture, with zero...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/20/2022Circuit/Chip Packaging PlatformThe VIPack™ packaging platform from Advanced Semiconductor Engineering Inc. is designed to enable vertically integrated package solutions.

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...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...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).
