Resource Development Experts.

Optical:

Fabricating using only the finest materials manufactured by the World experts in optical glass such as Schott^®, Hoya^®, Kopp^®, GE^®, Heraus Amerisil^®, and Dynasil^® starts us off with the base advantage in achieving the total quality we need to service you. There are many optical glasses and many more applications for each. Optical glasses are classified by their main chemical components and are identified by refractive index and Abbe-number. They are divided into groups depending upon the applications they are best suited to. The optimal glass type is established based on your application, then we go to work with our specialist to machine the glass to the precise specifications. Using our resource in the latest in CNC, water jet and other finishing equipment, we can satisfy requirements, from one piece to mass production. With our in house ability to add coating, source fixtures and assemble as necessary, we complete the "One Source" objective. "We make your glass dynamic."

Concave Lens or Convex Lens: Concave lenses diverges a beam of light from a distant source. The convex lenses and compound lenses focus light from a distant source to a point. The distance between the focus and the lens is called the focal length. The shorter the focus, the more powerful the lens.

Meniscus Lenses: A lens having two spherically curved faces, one convex and the other concave, so that it has the form of a shell. A positive meniscus lens is thicker in the middle than at the edges and serves as a converging lens; a negative meniscus lens thickens toward the edges and works as a diverging lens.

Convex Mirrors or Concave Mirrors: Convex mirrors create virtual images are formed by diverging rays; Concave mirrors create real images by converging rays.

Prisms & Cubes: We offer Prisms and cubes in a range of materials including BK7, Quartz, and Sapphire. If you need a non-standard prism, contact us at sales@glassdynamicsllc.com.

Optical Flats: Optical Flats have a precision polished flat surface used as a reference against which the flatness of a test surface may be compared. We offer single-sided optical flats in materials such as fuse silica, sapphire and Schott, Kopp and Hoya specialty glasses. Additionally, the flats can be enhanced with an aluminum coating to increase contrast and improve the visual reference.

Solar Cell Covers: With our diverse technology we have accomplished techniques to provide a range of solar cell covers in a diverse range materials including the superior quality of Dynasil fused silica as well as sapphire 12" x 3" x .003" polished on both sides for solar cell covers.

Spectrophotomer cells: Spectrophotometer cells are used for holding your samples to be measured for absorbance or transmission in all common spectrophotometers. Our focus is on quality of material, uniformity and conformance. The polished optical windows undergo rigid of inspections from raw material to matching of the finished cells to insure the product you receive is the best.

Reticle Substrates: We have a wide variety of reticles available. You can select your reticle from standard; scales, crosshairs, micrometers and targets for calibration of optical systems and microscopes. We also can create a custom reticle to your specifications.

Interferometer Plates: Our plane plates are produced as mirror substrates for use in interferometers. The material is fused silica with a transmission range of 180 or 270 to 2600 nm. The expansion coefficient is 0.5*10-6/K. The plates have a 30' wedge angle to eliminate back side reflections from the path of light. The cylindrical outer surfaces of the plates are polished. Contact sales@glassdynamicsllc.com for our table that lists the departures from parallelism of the matched surfaces of pairs of plates. The back surfaces are plane to l/10.

BeamSplitters: Beamsplitters use a class of diffractive glass to produce a lens that is the optical version of a copying machine. In other words, a beam splitter makes copies of the input beam and retains the divergence angle, diameter, and polarization of that input beam.

Photomasks: A high purity quartz or fused silica plate containing a precision image of integrated circuit or chips. Photomasks are used in lithographic tools, such as deep UV steppers. The light is projected through a photomask and high aperture lens. The light casts an image of the pattern on the photomasks onto a silicon wafer coated with a light sensitive material.

Waveplates aka Retardation Plates: Optical elements with two principal axes, one slow and one fast, which resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form a particular single polarized beam. Waveplates / retardation plates produce half - and quarter - wave retardations.
