This digital microscopy system is an ideal laboratory instrument for clinics, Vets, Doctors, and professional students. The T490B features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer or video screen while simultaneously obtaining sharp, focused images through the eyepieces. Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not simul-focal with the rest of the microscope optical system, you have to re-focus the microscope after each switch. This microscope system, however, erases this step by providing simul-focal viewing. Especially handy for teaching demonstrations, clinical examinations and laboratory applications, the simul-focal feature allows your students, patients or colleagues to view clear images simultaneously while you work through the eyepieces. In addition, the T490Bs industry standard 23mm photo port and C-Mount adapter allow you to attach most microscope digital cameras and video systems on the market. The T490B includes a 30-degree inclined 360-degree swiveling, compensation-free trinocular head, a 3D double-layer mechanical stage, and an intensity-variable halogen illumination system. The digital camera captures still images and video, and allows you to view a live stream on your PC. With software available for Windows, Mac, and Linux, its a multi-platform imaging solution. The included Windows software offers image-development and measurement tools, as well as advanced compositing features such as image-stitching and extended-depth-of-focus. Independent preview and capture resolutions allow you to view high-speed video while capturing high-definition images. For Mac and Linux, there is a lite version with limited processing features. This digital microscopy system is perfect for teaching demonstrations, clinical examinations and labo
