Prisms

Prisms are available as:

  • Right-angle prisms
  • Rhomboid prisms
  • Penta prisms
  • TIR prisms
  • Beamsplitter cubes
  • Roof prisms
  • Porro prisms

Diameter sizes range from 10 - 150 mm depending on customer specification.

 

Prisms can be supplied as:

  • Cut prisms
  • Milled prisms
  • Polished
  • Polished / coated prisms

 

Two different manufacturing processes are possible at SCHOTT to offer the best possible quality and improve manufacturing efficiency:

1. Pressing

Melting → Pressing → Polishing → Coating

 

2. CNC machining

Melting → CNC-sawing → Polishing → Coating 

 

Quality Assurance / Metrology

  • Measuring of surface flatness with interferometer (λ/10 accuracy).
  • Measuring of surface quality with a white light interferometer.
  • Measuring of 3D dimensions with Zeiss Vista CMM.

Lenses

SCHOTT manufactures a vast range of lenses in a variety of shapes and sizes. As one of the most versatile and widely used optical components, they can be made using one of 120 different glasses, with spherical or aspherical surfaces, and composed of a single material or doublets.


Spherical lenses

Spherical lenses are available as:

  • Lenses plano-convex/plano-concave
  • Lenses bi-convex/bi-concave
  • Achromatic doublets or triplets
  • Meniscus lenses

Diameter sizes range from 3 - 90 mm depending on customer specification.

Spherical lenses can be supplied as:

  • Pressings
  • Polished or coated spherical lenses
  • Cemented (singlets, doublets, triplets)


Aspherical lenses

SCHOTT Aspherical Lenses offer superior image quality, an improved surface, custom design, flexible production, and enhanced total light transmission, all in a wide range of glass materials.

To find out more, please see related product “Aspherical Lenses” on the overview page.

Plano optics

Plano optics are available as:

  • Optical windows
  • Protective windows
  • Optical flats
  • Substrates for microlithography
  • Brewster or elliptical windows
  • AR coated laser line windows
  • Dielectric and metallic mirrors
  • Dichroic long- and shortpass filters
  • Narrow bandpass filters

A wide range of optical materials can be processed into plano components, including SCHOTT's portfolio of optical and filter glasses, fused silica, sapphire and ZnS.

Plano components are produced by double-side polishing for best-in-class transmitted wave front or single-side polishing for excellent flatness.

Diameter sizes range from 2-625 mm depending on customer specification. Drilling, dicing and complex CNC machining for final shaping are available, as well as customized coatings from UV to IR designed to your exact requirements.
