What is an autocollimator?
Autocollimator is a device used to measure small angles with extreme accuracy. There are a number of applications for this type of device, especially in sciences where accurate measurements are critical for many tasks. They can be used to collect observations, calibration of scientific equipment, measurement of experimental results and leading telescopes and other optical devices. Suppliers of scientific equipment and optics can carry autocollimators and can order them on request if the customer has a specific need. The mirror reflects the light back to the autocollimator. With a digital device, the light hits a sensor that measures deflection to determine the angle of the target. It is also possible to see the eyepiece with the Meteli, the small grid with the marks, to measure the deflection manually by looking at the position of the light shifted on the return.
The various factors make it impossible to project the beam perfectly straight, even light, and to make the reflection absolutely perfect. Technicians calibrate the device to take into account problems, such as temperature differences that can cause light to swallow slightly. This compensates for real -time measuring errors and allows scientists to rely on measuring devices. Thanks to the high sensitivity of these devices, it is important to regularly check, calibrate and maintain their best results.
Scientists can use an autocollimator to perform measurements without actually touching the target. No physical contact is required because the device uses light to measure. This can be useful in different environments where people may not want to disturb anything. The device can also make repeated measurements of the same tar over time to monitor movements and changes. Digital devices can be programmed to automatically react and record at the set intervals.
6 These devices use lasers and it is important to be careful around them. Someone standing in the path of the beam can experience afterEye damage, especially during repeated exposures. The area in front of an autocollimator should be checked and cleaned before use and the staff around the device should be trained in laser safety.
