Capabilities

Flat Optical Elements

Flat optical components have one or more plano polished surfaces. Our product offering includes items with parallel or wedged surfaces like mirrors, windows, wedges, etc. as well as all types of prisms. Furthermore we offer color glass filters, thin film filters, beamsplitter plates and cubes. Special capabilities in micro optics (down to 0.2 mm) and large components up to 3200 x 400 mm complete the product line. One of our key differentiators is highly accurate surfaces on large substrates (e.g. lambda/4 on 300 mm diameter).

Depending on material and geometry the following
specifications can be achieved:

  • Dimensions from 2 mm up to 1000 mm or more
  • Surface flatness up to lambda/40 P-V
  • Parallelism or angular accuracy of 1 arc sec
  • Surface quality up to 5 / N x 0.001 according to ISO 10110-7

    • Curved Optical Elements

    Curved optics are components with one or more spherical or aspherical surfaces. Our capabilities include singlet lenses like plano-convex, plano-concave, bi-convex, bi-concave or meniscus lenses as well as cylindrical lenses. Additionally achromats and other multi-element lenses made of different materials are manufactured according to your design in order to meet your requirements.
    Depending on the type of component and material
    requested the following specifications can be
    achieved:

    • Dimensions up to 150mm or higher on request
    • Surface flatness up to lambda/10 P-V
    • Surface quality up to 5 / N x 0.001 according to ISO 10110-7

    Optical Coatings

    Our optical components can be supplied coated or
    uncoated. With the latest technology of coating equipment
    we provide:

    • AR–coatings like single layer (R<1.5%), multi-layer (R<0.25%), broadband (Ravg<0.4%) or laser grade (R<0.15%) with selectable wavelength / wavelength range
    • Metallic reflective coatings as Aluminum, Silver or Gold
    • High reflective dielectric coatings (R>99.8%)
    • ND-Filter coatings
    • Dichroic filter coatings (color filter, heat reflection, cold-light, etc.)
    • Beam splitter coatings (single wavelength or broadband for VIS, UV, IR, polarizing or non-polarizing)
    • Other coatings on request

    Consistent quality can only be ensured by clear procedures
    and appropriate measuring devices. Therefore we use the
    most up-to-date equipment to guarantee the quality of our
    products to reach maximum customer satisfaction.
