Request InfoPoco Graphite Inc., Specialty MaterialsSupersic, Poco Graphite’s high-performance silicon carbide, is an ideal material for fabricating optical benches. Complex geometries are easily fabricated and then mated with silicon carbide mirrors for optimum performance. Poco’s unique silicon carbide manufacturing method allows complex machining to take place in the graphite precursor; this is important because silicon carbide is very difficult and inefficient to machine. Graphite parts are assembled and subjected to a chemical vapor conversion (CVC) process which produces a pure silicon carbide monolithic structure. During the CVC process...See full productRelated content from Photonics MediaPRODUCTSPromoted Content July 2020 IssueAplanatic ObjectiveThe aplanoXX_NA0.8 objective for diffraction limited focusing from AdlOptica GmbH features a numerical aperture of 0.8 inside transparent materials with compensation for spherical aberration at...BioPhotonics May/Jun 2020 IssueField Flow Fractionation SystemThe EAF2000 Electrical and Asymmetrical Field Flow Fractionation System from Postnova Analytics GmbH is designed to enhance the separation and characterization of biopharmaceutical, environmental,...Photonics.com 12/16/2020Super-resolution MicroscopeThe OptoNano 200 super-resolution microscope from OptoSigma Corp. incorporates optical microsphere nanoscopy technology.

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 HandbookNanopositioning: A Step Ahead: It is almost a cliché among students of creativity that innovation occurs at the intersection of fields. Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer.
