WEILHEIM/TECK, GERMANY —The use of UV-C lamps for sur- face sterilization is an effective tool in the fight against the spread of infection with SARS- CoV-2 and other droplet infec- tions which remain on surfaces over a longer period. In order to break infection chains, there is an urgent need for devices which can be used for inactivation of SARS-CoV-2 viruses on contami- nated surfaces with an exposure time of just a few seconds. The coronavirus pandemic
has created high general demand for UV lamps and UV systems for decontamination of entire rooms which were previously

from ROHM SANTA CLARA, CA — ROHM Semiconductor today announced the BD8758xY series (BD875 - 81YG-C, BD87582YFVM-C) of rail- to-rail input/output high-speed CMOS operational amplifiers. The devices feature improved EMI immunity for automotive and industrial equipment appli- cations requiring high-speed sensing in harsh environments, such as vehicle engine control units and anomaly detection sys- tems for factory automation equipment. In recent years, advance-
ments in electrification and mounting density have increased the amount of environmental noise in electric vehicles and cars equipped with Advanced Driver Assistance Systems (ADAS). Generally, however,
it is
extremely difficult to carry out noise evaluation on individual boards and systems during auto- motive development since this must be performed after assem- bly. Moreover, some results require improvements such as large-scale EMI countermea- sures to lower noise. In response, ROHM re -
leased the EMARMOUR™ series in 2017 that has been well received in the automotive and industrial markets due to superi- or noise immunity that reduces design resources by combining a vertically integrated production system with proprietary analog design technology. The EMAR- MOUR series is designed to pre- vent malfunctions due to noise without the need to take special
application measures. Contact: ROHM Semicon - ductor USA, 2323 Owen Street,

used exclusively for the steriliza- tion of medical devices. One validation method for
UV-C lamps is measurements of the irradiance. The simplest device for such measurements may be a UV radiometer with a measuring head adjusted to a wavelength of 200 to 280 nm. The sensitivity range of the measuring instrument requires particular attention; this must also be within the appropriate limits. In order to make the use of disinfection lamps possible in complex installations and not
just as standing emitters possi- ble, goniometric measurement of the radian flux from the lamp, which radiates in various direc- tions, is vital.
GL Optic offers solutions
and approaches for the measure- ment and calculation process, presentation of the radiometric data and values and the appro- priate measuring instruments such as radiometers with a soft- ware for simulation of the distri- bution of radiant intensity on the
selected room surface. Contact: GL Optic,
