Fresnel light

The Fresnel Effect was first documented by the French physicist Augustin-Jean Fresnel (1788-1827), who advanced the wave theory of light through a study of how light was transmitted and propagated by different objects. In addition to the Fresnel Effect, Augustin-Jean Fresnel is also known as the inventor of the Fresnel Lens, which is still used in lighthouses around the world, and is used in film production on a Fresnel Light.

Fresnel Shaders in general allow reflection, specularity, and other attributes to vary according to the viewing angle of a 3D surface.  A Fresnel shader will let you specify a specular color for parts of a surface directly facing the camera, and another specular color to be seen on parts of a surface that are perpendicular to the camera. In addition to the usual specular highlights and reflectivity, parameters such as the color or transparency can also be controlled by some Fresnel shaders.

When we talk about simplicity we mean several things, for example, simple to place or mount the measurement equipment on the measurement object, easy to perform the measurement and easy to interpret the measurement result. With Easy-Laser® E710 you can measure all types of rotating machinery, large and small, equally well, regardless of shaft diameter.

Wireless measuring units (laser/detector) enable you to work more freely. The measurement values can be registered with only 40° rotation of the shafts. You can then align it ”live” using the measuring units in any position around the shaft. The programs guide you step-by-step through the measuring procedure for the perfect measuring result.Include  :1 Measuring unit M  1 Measuring unit S 1 Display unit2 BT wireless units2 Cables 2 m2 Shaft brackets with chains 2 Extension chains2 Magnet bases2 Offset brackets4 Rods 120 mm  [4.72”]4 Rods 60 mm  [2.36”]1 Measuring tape 3 m  [9.8’]1 Manual1 Quick manual1 USB memory stick with EasyLink™ software1 USB cable1 Charger (100–240 V AC)1 Toolbox1 Shoulder strap for display unit1 Optical cleaning cloth 1 Carrying case

Easy-Laser E710 is an alignment system that is complete in its full meaning. It does not just give you all the functions for shaft alignment, it also gives the opportunity to check the machine base and any bearing play using the standard equipment.​

Fresnel Effect (pronounced "fre-nel," the "s" is silent) - the observation that the amount of reflectance you see on a surface depends on the viewing angle.  As shown in the renders above, if you look straight down from above at a pool of water, you will not see very much reflected light on the surface of the pool, and can see down through the surface to the bottom of the pool.  At a glancing angle (looking with your eye level with the water, from the edge of the water surface), you will see much more specularity and reflections on the water surface, and might not be able to see what's under the water.

Programs for horizontal machines, soft foot checks, machine trains, vertical/flange mounted and cardan/offset mounted machines are included. Furthermore programs for straightness, flatness/twist and parallelism measurement are included. Using accessories you can also align sheaves/pulleys with digital precision and check vibration levels. Large, clear colour screen, wireless measuring units (included as standard), long operating life and robust design give a measurement system that is both reliable and easy to use.
