The concept of a laser level has been around since at least the early 1970s, [2] the original spinning-mirror design laser plane and line level was patented by the late 1980s, [3] and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late ...
The term dumpy level (also builder's level) endures despite the evolution in design. They can be manual or automatic, the latter being much quicker to set up. A tilting level is a variant which has a precision vertical adjustment screw which tilts both the telescope and the high accuracy bubble level attached to it to make them level. This ...
A wooden tripod holding an optical level is set up firmly on the ground. Levelling or leveling (American English; see spelling differences) is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum.
Re-center the cross-hairs using the thumb screws, then fine-tune the level using the tripod legs. Once the tribrach is nearly centered over the marker, level the tribrach the last little bit using the thumbscrews. Slacken the tribrach from the tripod head and slide it the last 4-5mm so that it is centered over the marker and is level.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
A surveyor's tripod with a shoulder strap. The head of the tripod supports the instrument while the feet are spiked to anchor the tripod to the ground. A surveyor's tripod is a device used to support any one of a number of surveying instruments, such as theodolites, total stations, levels or transits.
A tubular spirit level A bull's eye spirit level mounted in a camera tripod. A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical . Two basic designs exist: tubular (or linear) and bull's eye (or circular).
A tripod is also helpful in achieving precise framing of the image, or when more than one image is being made of the same scene, for example when bracketing the exposure. The use of a tripod may also allow for a more thoughtful approach to photography. For all of these reasons, a tripod of some sort is often necessary for professional photography.
