USHIO UV irradiance meter offers thin form factor for optical film process control

July 9, 2012 — Ushio Inc. (TOKYO:6925) launched its thinnest ultraviolet (UV) irradiance meter "UIT-q365 (UIT-Theta365)." The meter is 4.9mm thick, used to keep major UV processes within spec. It can be used during optical film manufacturing for flexible electronics, as well as during adhesion of precision optical parts.

The meter is launching at SEMICON West 2012. USHIO will also demonstrate its dedicated Android application “BladeNavi,” used for measurement, monitoring, and analysis of UV irradiance, which is set to launch in October 2012.

The UIT-q365’s thin unibody design incorporates a meter, sensor, and secondary battery to allow measurement of UV irradiance in hard-to-reach locations or in-situ setups. Measurements are reportedly highly accurate and repetitive measurement even for scattered continuous light. With a rechargeable battery, re-use is unlimited.

The product operates in- or off-line. In off-line data-logging mode, it can be placed on a film running on a production line to log measured data, then removed from the line for processing measured data. In on-line mode, it provides real-time measurement of irradiance of a spot UV light. With “BladeNavi” the tool can be operated with one hand.

Visit USHIO at SEMICON WEST, July 10-12 in San Francisco at the Moscone Center, South Hall, Booth 2544.

USHIO INC. handles a variety of light sources for a broad range of industrial applications, including high-brightness discharge lamps for cinema projectors and data projectors as well as halogen lamps for general lighting and OA equipment and UV irradiance meters. It also manufactures and markets products incorporating its own light sources, such as optical systems for manufacturing FPDs and other electronic components and devices as well as imaging equipment led by digital cinema projectors.
