Abstract: An optical system may include a light source to provide a beam of light. The optical system may include a reflector to receive and redirect the beam of light. The optical system may include a light gate having an opening to permit the beam of light, from the reflector, to travel through the opening. The optical system may include a light sensor to receive a portion of the beam of light after the beam of light travels through the opening, and convert the portion of the beam of light to a signal. The optical system may include a processing device to determine whether a notch of a wafer is in an allowable position based on the signal.

Abstract: A composition for inhibiting skin cell proliferation and/or anti-inflammation is provided. The composition for inhibiting skin cell proliferation and/or anti-inflammation includes: apigenin and luteolin, wherein a weight ratio of the apigenin to the luteolin is about 1.5-25:1, or a mole ratio of the apigenin to the luteolin is about 1.5-25:1. Moreover, the apigenin and the luteolin have a synergistic effect on inhibiting skin cell proliferation and/or anti-inflammation.
