Ultra-Wide Angle View: This 2.1mm lens offers a 153-degree field of view, providing a comprehensive and expansive surveillance area, ideal for monitoring large spaces such as warehouses or public areas. Advanced Detection Features: The camera is equipped with human body detection and vehicle detec...
image. The shorter the focal length, the wider the field of view, and the longer the focal length, the narrower the field of view. For example, a 100mm lens has twice (2x) the focal length of a 50mm lens, so it will have a field of view that is 1/4 the size (1/2 x 1/2...

Example 2: Calculate the field of view diameter for a 45× objective lens if the field of view for an objective lens 5× is 3 mm. Example 3: Estimate the size of a specimen for the field view determined in Example 2 if the number of objects, which fit across the field of view is...
A 7mm focal length lens is always a 7mm focal length lens and a 300mm focal length lens is always a 300mm focal length lens Field of View: The field of view of a lens (sometimes called the angle of coverage or angle of view) is defined as the angle (in object space) over which ...
To calculate the field of view of microscope you need to know the eyepiece magnification, field number and objective lens. Once you have this information you can calculate the field of view of the microscope by dividing the field number by the magnification number. ...
[translate] aWhen using a 5x projection lens, a 100mm field of view is available without moving the workpiece. 当使用5x投影透镜时, 100mm视野是可利用的,无需移动制件。[translate]
The second lens subunit can include a negative lens element, followed by a positive lens element, followed by a plastic lens element having an aspherical surface. The projection lens has a field of view of at least 35° so that the overall projection lens system has a compact size. 展开 ...
A multiple field of view sensor lens assembly suitable for inclusion in an infrared imaging system. The lens assembly includes a rotatable telescope 10 for providing first and second fields of view for the sensor, the first field of view being along a first axis thereof L and the second field...
