弊社は創業以来、光センサメーカとして光検出技術を長きにわたり追求し、センサの設計・製造・開発を続けてきました。ピンホール検査ユニットは、その長年の経験から生まれた自社製の高感度光センサを最適な光学設計で搭載しており、ピンホールの検出において、最小1 μmまで検出できる高い感度を実現しています。
また、ロールtoロールの搬送ラインにおいては、最速600 m/minまでの高速搬送に対応可能です。
ピンホール検査ユニットを用いた光学式の検査手法では、液体、電界、磁場、電解液などのストレスにワークをさらしません。
そのため、液体につけることのできない紙や不織布など強度の低い素材の検査や、薬品や食品のパッケージといった繊細かつクリーンな扱いが求められる製品の検査を可能とします。
