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
  • 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 or S-D 10-5 according to MIL-PRF-13830B

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 or other multi-element lenses made of different materials are manufactured to print or designed to meet your requirements.

Depending on the type of component and material requested the following specifications can be achieved:

  • Dimensions up to 150mm or more on request
  • Surface figure up to lambda/10 P-V
  • Surface quality up to 5 / N x 0.001 according to ISO 10110-7 or S-D 10-5 according to MIL-PRF-13830B

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. In our QC rooms we use.

Measuring Equipment

Interferometers
- Zygo-GPI-XP
- LT Ultra-12"
- Fisba µPhase® FS50
- Fisba µPhase® FST H100

Spectrophotometer
- PerkinElmer Lambda 950
