Description
本特許出願は、「PLASMA SOURCE LAMP HOUSE CORRECTION METHOD」と題し、Shiyu Zhang,Mark Shi Wang,Ilya Bezelを発明者として、2018年7月31日に出願された米国仮特許出願第62/712,391号の、米国特許法第119条(e)の下での優先権を主張するものであり、その全体は参照により本明細書に組み込まれる。
18を介して放出される放射を捕捉するように構成される。例えば、検出器アセンブリ1228は、試験片1107から反射又は散乱された(例えば、鏡面反射、拡散反射などを介して)放射を受光し得る。別の例として、検出器アセンブリ1228は、試験片1107によって生成された放射(例えば、ビームの吸収に関連する発光など)を受光してもよい。検出器アセンブリ1228は、当技術分野で周知の任意のセンサ及び検出器アセンブリを含み得ることに留意する。センサは、限定的ではないが、CCD検出器、CMOS検出器、TDI検出器、PMT、APDなどを含み得る。
