| Abstract | The Ultra Slim Optical Pointing Device (USOPD) is a slim optical mouse as an input device for the application of wireless portable personnel communication device like a smart phone. In this paper, we have fabricated optical components of GaN LED based USOPD. The USOPD consist of illumination optical components and imaging lens. LED beam shaping lens consisting of both aspheric lens and Fresnel facet successfully machined by Diamond Turning Machine (DTM). Additional V-shaped groove with refractive-reflective surfaces (VGRRS) for beam path banding was fabricated by bulk micromachining of silicon and the shadow effect in thermal evaporation. Fabrications of imaging lens, arrayed multilevel Fresnel lenses, were fabricated on electron beam lithography, FAB etching. The proposed optical components are extreme compactness as well as high optical efficiency, thereby applicable to the ultra slim optical system like USOPD. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
