A lens of long focal length seems to bring things closer, just as a telescope does. As the focal length gets longer, less of the scene is shown (the angle of view narrows), but what is shown is enlarged (the magnification increases). …

Lens focal length is the most important characteristic of a lens. One of the prime advantages of a single·lens reflex camera or a view camera is the interchangeability of its lenses; the reason photographers own more than one lens is so that they can change lens focal length. …

Think of volume as the area of the base being pulled through the height of the rectangular prism. This would be: Base = length x width = l x w.

The zoom, or variable focal length lens offers several technical and visual advantages. To begin with you can just take out one lens instead of two or three of varying focal lengths. And within the limits of its zoom range you can continu­ously vary the size of the image-enlarging or reducing it until the right parts of the subject exactly fill the frame. …

Lenses of short focal length are also called wide-angle or sometimes wide-field lenses, which describes their most important feature they view a wider angle of a scene than normal. A lens of normal focal length records what you see when you look at a scene with eyes fixed in one position. …

a phenomenon where celestial objects exhibit an apparent motion about their true positions based on the velocity of the observer.

The Green Beam Laser Strike Safety 533, has a orange/peach Green Beam laser filter made of polycarbonate and provides 33% visible light transmission.

Hyperspectral imaging

In addition to the usual range of short-,  long-, and normal-focal-length lenses, other lenses, such as those shown here, can view a scene in a new way or solve certain problems with ease. …

Multispectral imagery is produced by sensors that measure reflected energy within several specific sections (also called bands) of the electromagnetic spectrum. Multispectral sensors usually have between 3 and 10 different band measurements in each pixel of the images they produce. Examples of bands in these sensors typically include visible green, visible red, near infrared, etc. Landsat, Quickbird, and Spot satellites are well-known satellite sensors that use multispectral sensors. Hyperspectral sensors measure energy in narrower and more numerous bands than multispectral sensors. Hyperspectral images can contain as many as 200 (or more) contiguous spectral bands. The numerous narrow bands of hyperspectral sensors provide a continuous spectral measurement across the entire electromagnetic spectrum and therefore are more sensitive to subtle variations in reflected energy. Images produced from hyperspectral sensors contain much more data than images from multispectral sensors and have a greater potential to detect differences among land and water features. For example, multispectral imagery can be used to map forested areas, while hyperspectral imagery can be used to map tree species within the forest.

A lens of normal focal length, as you might expect from the name,  produces an image on film that seems normal when compared with human vision. The image includes about the same angle of view as the human eye sees clearly when looking straight ahead, and the relative size and spacing of near and far ob­jects appear normal. …
