A hybrid device that we term G-Fresnel (i.e., grating and Fresnel) is demonstrated. It fuses the functions of a grating and a Fresnel lens into a single device. We have fabricated the G-Fresnel device by using polydimethylsiloxane (PDMS) based soft lithography. Three-dimensional surface profilometry has been performed to examine the device quality. We have also conducted optical characterizations to confirm its dual focusing and dispersing properties. The G-Fresnel can be useful for the development of miniature optical spectrometers as well as emerging optofluidic applications.
我们展示了一种我们称之为G-菲涅耳(即光栅和菲涅耳)的混合装置。它将光栅和菲涅耳透镜的功能融合到一个单一装置中。我们通过基于聚二甲基硅氧烷(PDMS)的软光刻技术制造了G-菲涅耳装置。已进行三维表面轮廓测量以检查装置质量。我们还进行了光学表征以确认其双重聚焦和色散特性。G-菲涅耳可用于微型光谱仪的开发以及新兴的光流体应用。
