Frequently Asked Questions

What is a conical diamond ATR prism?

A conical diamond ATR prism is a precision optical component used for Attenuated Total Reflectance spectroscopy. Its conical geometry can be integrated into probes, sensors and analytical instruments for direct contact with the material being analysed.

What are conical diamond ATR prisms used for?

They are used for in situ spectroscopy, continuous process monitoring, chemical analysis, quality control and material identification. Applications can be found in chemical, petrochemical, pharmaceutical, biopharmaceutical and food production.

Why is monocrystalline diamond used?

Monocrystalline diamond combines broad optical transmission with exceptional hardness, chemical resistance, thermal conductivity and dimensional stability. This makes it suitable for repeated measurements in demanding process environments.

Which spectral ranges can be used?

Depending on the diamond quality, geometry and optical system, conical diamond prisms can be used for measurements in the UV, visible, near infrared and mid infrared spectral ranges.

What is the advantage of in situ spectroscopy?

In situ spectroscopy allows material to be analysed directly within the process environment. This can provide faster information about composition and process conditions while reducing the need to remove samples for separate laboratory analysis.

Can the diamond cone be customised?

Yes. Dutch Diamond Group can adapt the dimensions, cone angle, optical surfaces, contact geometry, diamond grade and mounting interface to the requirements of the instrument and application.

Can conical diamond prisms be supplied mounted?

Yes. They can be supplied as free standing components or as mounted assemblies for integration into probes, sensors and OEM analytical instruments.

Can Dutch Diamond Group support OEM production?

Yes. Dutch Diamond Group supports customers from initial design and prototype development through testing, final inspection and recurring production.

What information is required for a quotation?

Please provide the required geometry, dimensions, spectral range, operating temperature, pressure, process material, chemical environment, mounting requirements and expected quantities. A drawing of the component or instrument interface is helpful.
