In the field of biomedical optics, laparoscopes for high temperature treatment of various internal tissues are widely used. With the help of medical endoscopes, it is possible to examine the internal cavities of the human body, biopsy, administer medications, remove tumors, and use laser radiation for surgical and therapeutic purposes. To achieve high performance of optical system’s combination of components made of optical polymers which are transparent in the long-wavelength spectrum are proposed. Technological aspects of optical systems are observed. Computer modeling of infrared endoscope system using Zemax software is presented. Selection of appropriate optical materials is described. Discussion of effective introduction of polymer components into the optical design is provided. Optical performance of the achieved endoscopic systems is shown.
Polymeric materials with optical properties are introduced widely into development of novel and complex optical devices. Applications include various imaging and illumination systems, medical devices, scanning and recognition of barcodes, fingerprint scanners, motion and presence sensors, CCD cameras, laser collimation systems, etc. To achieve high performance of optical systems combination of components made of conventional optical glasses and polymers is proposed. Such hybrid lenses could have decreased aberrations and improved image quality as well as be more compact and lightweight. Technological aspects of optical glass and polymer combination are observed in the paper. Computer modeling of a high-aperture hybride micro-lens using Zemax software is presented. Selection of appropriate optical polymers is described. Discussion of effective introduction of polymer components into the lens design is provided.
The paper is devoted to the description of the on-line course “Geometrical Optics” placed on the national open-education platform. The course is purposed mainly for undergraduate students in optics and related fields. We discuss key features of the on-line form of this course, the issues of its realization and learning outcomes’ evaluation.
