  • Mini-D2T & CHEM2000 (ISS-UV-VIS) Lamp Replacement
    The Mini-D2T and CHEM2000 ISS-UV-VIS light sources emit ultraviolet and visible light at approximately 200-1100nm. The lamp for these light sources has a lifetime of 800 to 1000 hours of standard use and must be replaced after its life ends or when it becomes weak and unstable. The following
  • UV Curing Adhesives and Potting Compounds
    . Ultraviolet curable formulations are materials that cure (harden or polymerize) when exposed to ultraviolet light. Epoxies Etc... has developed an extensive line of UV curing products designed to fit a wide range of electronic, aerospace, decorative, and medical device applications. Ultraviolet light
  • Calibration of the Broad Band UV Radiometer
    to meet the growing precision and accuracy requirements. In depth error analysis is also necessary to properly estimate the character and amplitude of errors incurred during the calibration procedure. A method for calibration of a broad band UV radiometer is proposed. In order to achieve the highest
  • Abbott Revives UV for Purified Water Pretreatment
    equipment. A reverse-osmosis (RO) system was considered, but would have been very expensive. Instead, the company decided to install 5-micron particulate filters for contamination control, and to rely on an out-of-favor technology, ultraviolet (UV) lamps, for dechlorination. Previous attempts to use UV had

    output to a UV-VIS S2000 Spectrometer using a 50-µm fiber. The PX-2's rep rate was 122 Hz. The parameters for the S2000 Spectrometer were as follows: * 16 ms integration time, * Pixel boxcar of 15, and * 16 scans averaged. A scan was collected every 5 minutes for 4 hours. The results of several
  • Measurement of Chlorinated Hydrocarbons with an 11.7 PID (.pdf)
    The first commercial photoionization detector (PID) was introduced in 1974 (1,2) by HNU Systems. This PID used a sealed short wavelength (121 nm/10.2 eV) UV lamp. In 1979, we introduced an 11.7 lamp in response to the need for detecting chloroalkanes for the chemical industry (VCM production

    wetting. Once that process is complete, a light source that is set to deliver a preset dose of UV light is triggered. This process results in the instantaneous hardening of the material, creating a very strong bond junction. Mercury arc lamps are commonly used for UV spot curing. A typical arc lamp
  • Medical Device Link .
    Recent developments in curing equipment UV lamp offers fast curing time A powerful UV lamp is suitable for curing adhesives, epoxies, resins, and other materials. The Maxima 3500, supplied by (Westbury, NY, USA), delivers an average UVA intensity of 100,000 �W/cm2 at 15 cm for rapid curing
  • Medical Device Link .
    . Whereas most other types of UV curing systems employ lamps containing mercury, pulsed UV uses xenon lamps. This frees the user from concerns about compliance with occupational and environmental regulations regarding mercury use and disposal. Furthermore, pulsed systems use only electrical energy
  • Lighting up the night
    emitters surrounded by a polycarbonate globe for weather and UV protection. Should one emitter in the cluster fail, others continue to provide light. Integral electronics creates a self-contained screw-in replacement for the original bulb. This cutaway diagram of a typical LED shows basic components
