  • UV-A LED Panel Flood Lamps

    PowerMAX™ 365 Series - Spectronics Corp

    PowerMAX 365 Series flood lamps feature a panel of 16 powerful UV-A (365 nm) LEDs specially engineered for non-destructive testing applications. These versatile, stationary light sources can be installed overhead or in-line, and can be ganged together to provide an even wider coverage area. UV-A LED panel flood lamps are also available in two standard-intensity models that are designed for NDT inspection applications requiring limited UV-A output.

  • UVB Sensor

    PMA 2101 - Solar Light Company Inc.

    The UVB sensor PMA 2101 biologically-weighted erythema gives an accurate measurement of ultraviolet radiation from sunlight or artificial light sources, also called sunburning UV radiation (SUV).Its spectral response follows closely the erythema action spectrum. The detector has angular response very close to an ideal cosine function (Lambertian response) making it suitable for measurements of diffuse radiation or radiation generated by extended sources.

  • 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.

  • Total Luminous Flux Measurement System

    OptCom Co., Ltd

    This system enables the total luminous flux measurement of luminous intensity distribution 2 and 4 light sources based on the measurement standards of LED lightings LM-78 and LM-79 approved by IESNA (Illuminating Engineering society of North America) .As a calibration function, it can do the self-absorption correction and the spectral intensity calibration based on the JIS C 8152 measurement methods.

  • 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.

  • Single Photon Counting Camera

    LINCam - Photonscore

    LINCam is a solution for scanning-free time correlated single photon counting implemented as a camera. This camera resolves x and y positions of individual photons as precise as a CCD with 1000 × 1000 pixels does together with 50 ps accuracy timing. Being paired with a pulsed light source LINCam turns any conventional fluorescence microscope into a powerful lifetime measuring instrument.
