What does 12cm look like?
Beside above, what does 4 cm look like? 1 inch is defined as 2.54 cm and 1 cm is smaller than 1 inch you divide the centimetres by 2.54, so 4 cm is 4 divided by 2.54 which is approximately 1.5748 inches. That depends on the frame of reference but in general and with imperial metric it's around 1,5748 inches.
How to read an inch ruler?
Read an English ruler using fractions of an inch. The distance between any two large numbered lines is 1 inch. The large unnumbered line that is halfway between them is 1/2 inch. The smaller (but still prominent) line between the 1/2 mark and the numbered inch line is 1/4 inch. The tiny little lines between all of the more prominent lines are 1/16 inch.
How to compare lengths of paper money?
Use standard objects to compare lengths, check your wallet, use any paper money to be our compare object, then search "the width of your paper money" online, when you know the width, you can adjust the ruler's PPI setting by it, you can compare to any standard size object at your side, e.g., coin, credit card, CD, paper money, mobile phone, in the office, a A4 size printable paper is a good comparison object, the longer the more accurate. Below ruler adjuster help us to calibrate accuracy more easily.
Image Size
- A lens produces images in the form of a circle,called the image circle. In a CCTV camera, the imaging element has a rectangularsensor area (the image size) that detects the image produced within the imagecircle. The ratio of the length of the horizontal to vertical sides of a videoimage is called the aspect ratio, which is normally 4:3 (H:V) for a ...
Relationship Between Angle of View and Imagesensor Size
- An important factor to remember is that cameraswith different image sensor chip sizes (such as 1/4", 1/3", 1/2",2/3" and 1"), using the same focal length lens, will each yield adifferent field of view. Lenses designed for a larger image sensor devicewill work on a new, smaller size camera. However, if a lens designed for asmaller format image sensor device (ie. 1/3") is placed on a larg…
Minimum Object Distance
- Minimum object distance (M.O.D.) indicates howclose the lens can be placed to the object for shooting. It is measured from thevertex of the front glass of the lens.
Flange Distance and Back Focal Length
- Distance between mechanical mount surface and theimage sensor (in air). C-Mount=17.526 mm / .690" CS-Mount=12.526 mm / .492" Back Focal Length Distance between vertex of the rear element lensand image sensor. C-Mount and CS-Mount Lens Compatibility When using a C-mount lens for a CS-mount camera,a C/CS-mount adapter (5 mm thick) is required between the lens an…
Angle of View and Field of View
- The angle of view is the shooting range that canbe viewed by the lens given a specified image size. It is usually expressed indegrees. Normally the angle of view is measured assuming a lens is focused atinfinity. The angle of view can be calculated if the focal length and image sizeare known. If the distance of the object is finite, the angle is not used.Instead, the dimension of the r…
Focal Length
- Parallel incident light transmitted into a convexlens converges to a point on the optical axis. This point is the focal point ofthe lens. The distance between the principle point in the optical system and thefocal point is referred to as the focal length. For a single thin lens, thefocal length is equal to the distance between the center of the lens and thefocal point. Zoom RatioZoom ratio is the r…
