Scheme Porro consists of 2 x regular rectangular prisms (e.g., BOC 15х50). It makes the offset of the optical axis of the lens that increase the stereo base. In the scheme of Roof, typically used the system of Schmidt-Pehan (for example, the MINOX BL 8x42 BR). It allows you to create a more compact binoculars without displacement of the optical axis of the lens. Beam path in the prism of the Schmidt-Pehan more than in porro prisms , so the demands on the transparency of the glass is higher than Roof prisms. In expensive series of binoculars Carl Zeiss (for example, Carl Zeiss 10x56 T*FL Victory) uses a system of prisms Abbe-Koenig ensure the best light transmission and preserving the compactness of the binoculars with the Roof prism.
When observing a significant contribution to the deterioration in the image quality makes the hand shake. To reduce this effect, manufacturers offer different solutions. For example, the Canon between the lens and the porro prism placed in a special stabilization system based prism with a variable angle. After the rejection of the optical axis of the device microprocessor system detects a displacement and actuates the mechanism of stabilization of the shape of the prism changes and deflects the light beam to compensate for the deviation. The system response time of the order of 1/1000 sec. In our online store you can buy any binoculars from budget to High End.
