SpectroscopySpectroscopy is the measurement of transmission, reflection or absorption characteristics of a material as a function of wavelength.

Knight Optical is proud to own a range of Varian Cary Spectrophotometers and attachments for accurate metrological testing of transmission, reflection and absorption characteristics. Our Varian Cary 5000 spectrophotometers have a scanning range between 175nm-3300nm and can measure up to 8 Abs.

Our DRA attachment allows us to test complex cube beamsplitters for reflection and transmission over the same wavelengths.

Knight Optical also owns a Cary 660 IR spectrophotometer used for transmission and reflection testing between 1.67μm – 44.44μm giving us the ability to quickly test all our IR transmitting materials and coatings with a high level of accuracy and repeatability.

We are also is also the first UK company to purchase the revolutionary Agilent Cary Universal Measurement Accessory (UMA) for our Cary 5000 spectrophotometers. The UMA is used to measure transmission, absolute reflection and scattering of optical components at angles of incidence over a 360° range.

This accessory is unique providing solutions in the areas of thin films and coatings, optics, glass and solar.  With the Cary UMA we can:

  • Gain deeper insights into sample characterization in both research and QA supported by unprecedented data quality in terms of accuracy and precision.
  • Save time and money by increasing our sample throughput in QA verification during manufacturing.
  • Improve quality of end product and reduce the financial risk of shipping faulty products through comprehensive, automated, unattended analysis.

Spectroscopy results are supplied as a graph and can be accompanied by excel data where requested. We can adapt our metrology reports to your specific needs. Contact our technical sales team to discuss how we can help you.
