  • Silicon photomultipliers (SiPMs)

    First Sensor AG

    Silicon photomultipliers (SiPMs) from First Sensor are innovative solid-state silicon detectors with single photon sensitivity. SiPMs are a valid alternative to photomultiplier tubes. The main benefits of these detectors are high gain, extremely good timing performance and low operating voltage. They are insensitive to magnetic field and have a high integration level. The detectors are optimized for Near Ultraviolet (NUV) or red, green and blue (RGB) light detection with peak sensitivities at 420 nm or 550 nm.

  • UV Meter

    A-SUN TEST LTD.

    This affordable UV meter detects both atmospheric UV-A and UV-B light ranging from 400 nm to 280 nm. It displays the current atmospheric UV index and the UV Irradiance. UV-A and UV-B are the UV rays that penetrate the atmosphere. A graphical meter alongside a UV color code chart makes it easy to determine the level of UV risk.

  • Tachometers/Stroboscopes

    Shenzhen Graigar Technology Co.,Ltd.

    Measurement of the speed of a rotating shaft is acommon requirement in many industrial andlaboratory applications. Such measurements haveusually been carried out in the past with the help ofcontact type tachometers with friction drive. Morerecently digital optical non-contact tachometershave been designed which count the reflectedpulses from a white patch on the shaft and thendisplay the speed in rpm. The light source isusually a filament lamp operating with dry cellsleading to limited life and illumination. A similar ideawith magnetic pick-up from a particular area of theshaft has also been used for speed measurement.
