Frequently Asked Questions

What is a diamond optical window?

A diamond optical window is a transparent component that allows optical radiation to pass through while protecting an instrument, sensor or process from external conditions. Diamond provides optical transmission combined with exceptional hardness, chemical resistance and thermal conductivity.

Why is diamond used for optical windows?

Diamond is used when conventional optical materials cannot provide the required combination of transparency, wear resistance, mechanical strength, chemical stability and heat dissipation.

Which applications use diamond windows?

Diamond windows are used in spectroscopy, analytical instruments, optical sensors, laser systems, X ray equipment, semiconductor processing, high pressure research and other demanding scientific and industrial systems.

Which spectral ranges can diamond windows transmit?

Depending on the selected diamond material and grade, diamond windows can be used across UV, visible, infrared and other specialised spectral ranges. The exact transmission characteristics depend on material quality, thickness, surface finish and possible coatings.

Does Dutch Diamond Group manufacture custom diamond windows?

Yes. Dutch Diamond Group manufactures diamond windows according to customer drawings and technical requirements. Dimensions, thickness, geometry, surface quality, parallelism and wedge angle can be customised.

Which shapes are available?

Diamond windows can be produced in round, square and rectangular geometries. Other customer specific shapes can be evaluated by our engineering team.

What is a wedged diamond window?

A wedged window has two surfaces that are positioned at a small angle to each other. This geometry can help reduce unwanted interference effects and internal reflections within an optical system.

What is the maximum window size?

Dutch Diamond Group currently manufactures diamond windows with dimensions up to 30 mm. The achievable dimensions and tolerances depend on the required geometry, thickness, diamond grade and surface specifications.

Can diamond windows be supplied mounted?

Yes. Diamond windows can be supplied as free standing components or mounted in customer specific holders. The mounting method is selected according to the optical, mechanical, thermal and chemical requirements.

How is the surface quality inspected?

Dutch Diamond Group uses white light interferometry and other inspection methods to evaluate surface roughness, flatness and relevant dimensional characteristics. Measurement reports can be supplied when required.

What information is required for a quotation?

Please provide the dimensions, thickness, geometry, wavelength range, required surface quality, operating temperature, pressure, chemical environment, mounting requirements and expected quantities. A technical drawing is helpful when available.
