The present invention smartphones or tablets and paste it into the camera portion of the digital camera, and provides a high magnification / low power microscope magnifying lens which may be used while freely change the high magnification or low magnification of the lens. A high magnification / ...
depending on thezoommagnification,dueto the characteristics ofthelens,butthis is not a malfunction. en.leica-camera.com en.leica-camera.com 由於變焦倍率的關係,被攝物體可能會略微變形或輪廓會塗有顏色,這是由鏡頭的特性引起的,並 非故障。 us.leica-camera.com ...
More precise details compared to low-power lenses. High-power objective lens Magnification range and typical uses Magnification Range:40x to 100x or more Typical Uses:Detailed examination of tiny structures, studying individual cells,bacteria, or small particles. Characteristics and specifications: A sma...
Which lens has less power? Hence, the lens with a shorter focal length will have more power or higher refraction (causes more bending of light rays). While the lens with a longer focal length will have less power or low refraction (causes less bending of light rays). Thus, athick convex...
of one or two positive lenses, the fourth lens component is a negative meniscus lens with its convex surface positioned toward the object, and for which the number of lenses constituting the objective is small, the working distance is large, flatness of image is high and resolving power is ...
Low power magnification photography of thin sections Thin sections of any type of rock can be photographed at very low magnifications (1 to 3 times) using a 35 mm single lens reflex camera, bellows extension,... S.,D.,Heron - 《Journal of Sedimentary Research》 被引量: 0发表: 1968年 ...
The optical device includes a plurality of telescopic lens sets, for example, a plurality of telescopes, each telescopic lens set including an objective lens and an ocular lens, and a plurality of refracting optical elements, for example, prisms, positioned in front of at least some of the ...
摘要：PURPOSE:To obtain a titled lens which is long in its operating distance and also compact by constituting it of three groups consisting of a group having a positive composite power, a group of a negative lens, and a group of two positive lenses in order from an image side. ...
Interlocked with a magnification-varying mechanism that controls the position of the focal length-varying lens, the adjusting lens is moved to the on-the-axis location when the focal length-varying lens is in an area to provide high magnification, and to the off-the-axis location when low ...
