Consider it when you need to split light between a main optical path and a monitoring detector or second device. The reference spectrum describes the transmitted path; choose the required reflection ratio and angle of incidence with KUPO.\u003c\/p\u003e\n\u003ch3\u003eOptical performance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasured wavelength range:\u003c\/strong\u003e 300-800 nm.
