Request InfoNidek Co. Ltd.The RS-3000 Advance 2 optical coherence tomography (OCT) system from Nidek Co. Ltd. incorporates a scanning laser ophthalmoscope (SLO) and is designed for comprehensive imaging and analysis of the retina and indications of glaucoma. The RS-3000 Advance 2 retains some of the signature features of the previous model, including glaucoma analysis with a 9- × 9-mm-wide area normative database, accurate image capture with an SLO-based eye tracer, and selectable OCT sensitivity that allows acquisition of B-scan images through media opacities.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookAcousto-Optic Devices: Charts showing the characteristics of acousto-optic scanning devices, acousto-optic figures of merit, and solutions for common problems with acousto-optic processor devices.ACOUSTO-OPTIC SCANNING DEVICES: CHARACTERISTICS MODULATORS Material Bandwidth (MHz) Rise Time (ns) Acousto Input Power (W) (Saturation) Material Wavelength Range...Photonics HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market.
