Illumination lighting meaning

Light conductive fiber illumination (with LED light source) are first choice for applications that require higher brightness, for example for measurement of small prisms.

Not all light falling on an object is reflected. Some of the light is absorbed by the object. The amount of light an object can absorb depends on the object’s surface. Objects with white and shiny surfaces absorb a small amount of light falling on them, whereas those with rough and black surfaces absorb most of the light. Some examples of good light absorbers are blackboard and dark clothing.

The SIAM is a measuring device for determining the angle between the primary and secondary image on windscreens in accordance with ECE regulation ECE R43. The device consists of an eye-safe laser beam source (laser safety class 2), a testing telescope and the evaluation software. Due to the optical arrangement the measurement is independent of the distance between light source, windshield and testing telescope. The included software allows the automatic determination of the angle as well as the recording of the angle together with the corresponding measuring position on the windshield in a protocol.

The software always works in full screen mode.

The ELCOMAT® HR is a measuring instrument for applications with the highest demands on accuracy. Ultrastable mechano-optical design and specially developed evaluation and calibration algorithms are the basis for the excellent accuracy. This makes the ELCOMAT® HR ideally suited as a reference instrument for national calibration institutes.

You can operate two LED heads with the same or two different wavelengths with one control unit. Note: If you operate a collimator or autocollimator with LEDs of different wavelengths (e.g. with red LED head and then with green LED head), the collimator or autocollimator is defocused for one of the two wavelengths (chromatic aberration) and must be readjusted! For collimators and autocollimators with tube extension, refocusing can be performed quickly and easily by the operator.

Autocollimators are optical measuring instruments that can measure the smallest changes in the angular position of optical reflectors. In electronic autocollimators, the autocollimation image is detected by means of CCD lines or a matrix sensor. Electronic autocollimators are primarily used for the following measuring tasks: small angle measurement, ultra-precise angle adjustment and calibration, quality assurance of machine tools and their components, assembly automation, angular position monitoring. ELCOMAT® is a registered Union Trademark (EUTM 018002083), Trade Mark in CN, US (Int. Reg. No. 1476462)

Due to the phase shifting algorithm the software INTOMATIK-N offers higher accuracy and a larger measuring range with respect to surface form deviations in comparison to the INTOMATIK-S. Additionally the sign of the surface form deviation is automatically determined.

The auxiliary device for the GONIOMAT for angle measurement of prisms with fine ground surfaces. It consists of a collimator f=100 D40 and a deflection system for subsequent mounting on the granite plate of an existing GONIOMAT M5, M 10 or A5. The extension enables the measurement of ground prisms (roughness Rq = 1 .0 µm or less) with a maximum measurement uncertainty of 10 arc seconds.

Although both transparent and translucent objects transmit light that falls on them, they do reflect and absorb some amount of light. Otherwise, they would become invisible to us.

Most objects around us do not allow light passing through them at all. They can only reflect and absorb light. Thus we cannot see through them. These objects are called opaque objects. Some of the opaque objects are wooden bench, metal mug and ceramic pot. Objects that light are unable to pass through are made of opaque materials. Opaque materials either absorb or reflect the light. The amount of light that passes through is dependent on the opacity of the material an object is made.

Light can be absorbed. This is the reason why plants can make food for themselves during the day due to light absorbed from the sun, the light energy is converted into chemical energy, which is the sugar they made for themselves.

Diopter telescopes are adjustable focus telescopes that serve the measurement of optical power of lenses in diopter. The measuring result can be directly read from the diopter graduation.

The software is part of the GONIOMAT M and GONIOMAT A product series. It is characterized by a simple and sophisticated user interface and is executable under WINDOWS®10. The software enables standard-compliant evaluation of measurements (ISO 10110-1, VDI 2605 as well as DIN 3140) and offers comprehensive protocol functions. Further components of the software are tolerance specifications and checks as well as an innovative beam calculation based on ray-tracing.

The INTOMATIK-S software uses the static fringe evaluation method for calculating the surface shape deviation and is thus almost free of influences due to air turbulence or vibrations. However, the fringe evaluation does not achieve the same accuracy as the phase shift algorithm of the INTOMATIK-N software and also cannot automatically determine the sign of the surface shape deviation.
