New Case Studies

  1. Fluorescence Spectrometer

    The modular ZLX-FS fluorescence spectrometer is designed for the precise measurement of excitation and emission spectra from solid or liquid samples and has found application in many fields such as chemistry, physics, biology, medicine and environmental monitoring... [ more details ]
  2. Photoluminescence Spectrometer

    The measurement of photoluminescence from semi-conductor materials has become an important characterisation method and is widely accepted to provide information on for example: carrier doping levels, alloy compositions, film structures, band gap and edge effects, etc... [ more details ]
  3. Detector Spectral Response Characterisation

    The photoelectric detector is today used daily in all walks of life. One of the key measurements of performance is the spectral responsivity of such a detector... [ more details ]

Absorption / Transmission / Reflection Spectrophotometer

The ZLX-AS system is designed for high quality measurements with excellent stray light performance of absorption, transmission and reflectance from a wide range of solid and liquid samples. The system can be configured for use from the UV to IR spectral ranges by appropriate light source, monochromator grating and detector selection. Indeed by using an Omni-lambda 300 or longer focal length monochromator this system can continuously scan from UV to IR making it ideal for a range of samples that would be difficult to characterise with conventional spectrophotometer designs. The large sample chamber is fully modular and can accept a range of thin film, cuvette, and solid sample holders depending upon the application need and has fully adjustable optics to allow optimisation of the signal. Optional integrating spheres can be added if diffuse reflectance measurements are required.
