Abstract: A spectrum display method with photographic function includes collecting spectrum data and image data of a sample measurement device, controlling to display the spectrum data and the image data, recording the image data of the sample measurement device according to commands of shooting or recording the sample measurement device, associating the image data with the spectrum data, putting the associated data into an experiment image storage window, and performing operations of viewing, comparing, or editing the associated data; or saving the associated data as a record file; and loading the saved record file for performing the operations of viewing, comparing, or editing the record file. The image data includes photo data generated by shooting the sample measurement device or recorded video data generated by recording of the sample measurement device. A spectrum display system with photographic function is also provided.

Abstract: The present invention provides an improved optical reading and recording system utilizing optical system employing an aspherical solid immersion lens (SIL). The improved optical system has an aspherical SIL between an objective lens and the recording media. The aspherical SIL reduces the focused electromagnetic radiation beam spot size by providing an increased numeric aperture (NA) of the optical system. The aspherical surface of the SIL provide greater manufacturing and operating tolerances between the objective lens and the aspherical SIL. Greater manufacturing tolerances provide an easier to manufacture optical system. Increased ease of manufacture reduces the cost of optical systems.
