General Optical Engineering Questions 1. A laser writing system is used to produce high-resolution graphics. A photo-sensitive plate at the focus of the system is mechanically moved to trace out the desired graphics. The laser writing system consists of a collimated laser beam focused by a converging lens down to a small spot size. The laser beam propagates parallel to the axis of the lens. The performance of this optical system is most affected by which optical aberration? Circle the one best answer. a) Spherical aberration b) Coma c) Astigmatism d) Distortion e) Curvature of field f) Transverse chromatic aberration g) Longitudinal chromatic aberration h) None of the above 2a. A hemispherical solid immersion lens of radius R and refractive index n 1 is pictured below. Such a lens is used for reading compact disks (CD’s). It is surrounded by a re- fractive index of n 2 .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
