Collimator is an optical measuring instrument, by focusing and separating the light, so that it can be used to measure the deviation angle, flatness and straightness of various objects and other parameters. Collimator consists of several optical components, including light source, collimator, reflector, objective lens, eyepiece and so on.

• Aerospace: In the aerospace field, collimator is mainly used to measure the attitude, flatness and other parameters of the aircraft. For example, in the process of aircraft manufacturing, it is necessary to measure the geometrical parameters and positional relationship of each part of the aircraft to ensure the structural accuracy and navigational safety of the aircraft.

• Manufacturing: In the manufacturing industry, collimators are mainly used to measure parameters such as deviation angle and flatness of parts. For example, in the process of automobile manufacturing, collimator can be used to detect the deviation angle and rotation axis of engine and wheel.

• Civil engineering: Collimators are also used in civil engineering to measure parameters such as perpendicularity and levelness of buildings. For example, in the manufacturing process of precast concrete structures, collimators can be used to detect the straightness and flatness of columns and beams.

• High-precision Measurement: The collimator adopts optical principle, which can realise high-precision measurement, and the precision can be up to several digits after the decimal point.

• Mass measurement: the collimator can automatically record the measured values, and can measure many parameters of the objects in large quantities.

• easy to operate: collimator operation is simple, without excessive professional knowledge and skills.

Collimator is a very important measuring instrument, which is widely used in aviation, aerospace, manufacturing and other fields. Collimator achieves high precision measurement through optical principle and can measure a large number of multiple parameters of various objects.
