Description Microscope B-190TB. Didactic and laboratory microscope for routine applications, with built-in camera and removable 8.9” full HD tablet included. Stable and ergonomic metal stand that allows observation with transmitted light. Tablet with OPTIKA exclusive removable stand. Features: Handling: The “tablet” can be tilted in all directions what facilitates vision during demonstrations. The simultaneous data and power feed make this machine ideal for long term operation. The “tablet” can be detached from the microscope and used as a laptop. Optical system: The optical system has been developped for the most demanding users; it consists of high quality components which guarantee a high image contrast and an excellent optical resolution. The optical components have been designed and treated with special techniques to prevent the formation of moulds and fungi. Stand: The stand has a modern and ergonomic design. It is easy to carry the microscope thanks to the large opening behind the revolving nosepiece, to be used as a handle. The opening allows the user to see clearly the objectives and the samples used in discussion groups. Mechanics: The moving parts are made by means of a computerized numerical control system reducing manufacturing tolerance and increasing the reliability of the instrument. The strict controls on materials and production processes comply with ISO 9001:2008 quality system. Illumination: X-LED² type with white LED; light intensity control using a knob on left side of the frame. LED power 3W, comparable to a 30-35W halogen bulb. Camera: Digital camera resolution: 3.14 Mpx. Signal output: USB 2.0 - Sensor size: 1/2.5” Sensor technology: CMOS- Image format: 4/3 Full Image Size: 2048x1536. NO driver (microsoft driver). Capture features: continuous auto exposure, image size, image capture, compressed video capture. Control parameters: brightness, gain, exposure time, colors, color enhancement.
