Custom Diamond Optical Windows
Optical Performance in Demanding Environments
Dutch Diamond Group develops and manufactures precision diamond windows for analytical instruments, optical systems, sensors and other demanding technical applications.Diamond combines broad optical transmission with exceptional hardness, chemical resistance, mechanical strength and thermal conductivity. This makes it an excellent window material for applications in which conventional optical materials are affected by wear, heat, pressure, radiation or aggressive chemicals.
Our diamond windows can be produced in round, square and rectangular geometries. They are available as parallel or wedged windows and can be supplied as free standing components or as complete mounted assemblies.

Surface Quality and Inspection
The optical performance of a diamond window depends on surface roughness, flatness, parallelism, thickness and the quality of the selected diamond material. Dutch Diamond Group uses advanced white light interferometry to characterise polished diamond surfaces at micro and nanometre scale. This allows us to inspect surface roughness, flatness and other relevant characteristics according to the agreed specifications.
Measurement and inspection reports can be supplied upon request.
Parallel and Wedged Windows
Parallel diamond windows are suitable for many transmission and protection applications.
A controlled wedge angle can be applied when internal reflections or interference effects must be reduced. The appropriate geometry depends on the wavelength range, optical configuration and intended use of the window.
Free Standing and Mounted Windows
Diamond windows can be supplied as free standing optical components or mounted in customer specific holders.
We select the mounting method and holder material according to the mechanical, thermal, optical and chemical requirements of the application. Our engineering team can support the development of the complete window assembly for integration into an OEM instrument or technical system.
Customer Specific Development
The appropriate diamond grade, thickness, geometry and surface specification depend on the intended wavelength range and operating conditions. Dutch Diamond Group works closely with customers to determine the correct balance between optical performance, mechanical strength, manufacturability and cost.
