浜松ホトニクスは、量子カスケードレーザ（Quantum Cascade Laser、以下QCL ※1）の開発で培ってきた量子構造設計技術と回路設計の工夫により、中赤外光に感度を持つ光検出器「量子カスケード光検出器（Quantum Cascade Photodetector、以下QCD） P16309-01」の製品化に世界で初めて成功しました。実用化されている室温動作の中赤外光検出器では世界最高となる、遮断周波数(※2) 20ギガヘルツ（以下GHz）の本製品を分析機器の光検出器として用いることで、燃焼や爆発などの化学反応をピコ秒（以下ps、ピコは1兆分の1）単位で計測できることから、従来は不可能だった極めて短い時間間隔での分析が可能となります。また、高速大容量の空間通信や長距離向けLiDARなどへの応用も期待されます。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
