  • The CAS 140D represents the fourth generation of the worldwide extremely successful series of high-end array spectrometers from Instrument Systems. It combines all advantages of the CAS 140CT in terms of measurement accuracy and reliability with sustainable technical optimization for increased repeatability and stability in every environment. It offers even more versatile applications – from the reference instrument in national calibration laboratories to continuous production. A wide range of accessories complement the spectrometer to create a complete system for a wide range of spectroradiometric and photometric measurement tasks. Thanks to the modern housing and improved optical and mechanical design, the instrument is more functional, but smaller and simpler to integrate into existing measurement environments.

    Features:

    • High-end CCD detector, cooled and back-illuminated
    • Down to 4 ms integration time
    • Spectrograph with minimum stray light and enhanced throughput
    • Integrated density filter wheel
    • USB, PCIe or Ethernet interface
    • "Plug & play" accessory identification
  • LGS 350 Goniophotometer
    The LGS 350 Goniophotometer / Goniospectroradiometer was developed for the analysis of angle-dependent spatial radiation properties from small to medium-sized SSL luminaires and LED modules....

  • The LGS 350 Goniophotometer / Goniospectroradiometer was developed for the analysis of angle-dependent spatial radiation properties from small to medium-sized SSL luminaires and LED modules. The test specimen is operated in a horizontal burning position and measurements can be taken at an angular range of ±160° in the gamma / theta axis. Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index are determined as a function of angle.

    The LGS 350 comprises the goniometer with a sample plate for fixing the test specimen and the LGS Controller that drives the stepper motor and the angle display. If a photometer is used, the LGS Controller also displays the measured values in candela or lux.

    Features

    • Type C goniophotometer with horizontal optical axis
    • For samples up to 700 mm diameter and 8 kg weight
    • Accurate determination of the luminous intensity distribution and luminous flux
    • Angular-resolved analysis of spectral and colorimetric quantities
    • Data export in IES and EULUMDAT format
  • Integrating Spheres

  • Assessment of the total radiant power or luminous flux of light sources using integrating spheres is one of the most important tests in light measurement. The inside surface of an integrating sphere is coated with a diffusely reflecting material which guarantees complete integration and homogenization of the emitted radiation. The integrated light is then measured at the detector port.

    Instrument Systems has developed a complete series of integrating spheres, available in a wide range of sizes and providing functionality for a broad spectrum of applications. A deciding factor in choosing the appropriate integrating sphere is the maximum dimension of the light source to be measured. Larger sources require the use of larger integrating spheres in order to keep measurement errors to a minimum.

    All integrating spheres have a side entrance port for determining luminous flux in the 2π configuration (i.e. for determining emission into the forward hemisphere only). With the larger integrating spheres, the test object can also be mounted in the center, thus permitting measurements in the 4π configuration (i.e. for determining emission in all directions).  

    The latest integrating spheres are specifically designed for measuring UV sources. They use polytetrafluoroethylene (PTFE) which is highly reflective in the UV spectral range down to 200 nm. It therefore allows high throughput, even for challenging UV-B and UV-C emitters. In combination with the proven CAS array spectroradiometers reliable and precise UV measurements are guaranteed.
