LASER CONFOCAL AND LASER TRIANGULATION

The confocal laser sensor uses a blue laser source and is ideally for measuring solar cells. The sensor is available on all systems. The DSR-500 is ideal for measuring thick-film on a variety of substrates. It is available for the VANTAGE 50.

A laser beam is focused on a specimen through an objective lens that moves rapidly up and down. When the objective moves closer to or further away, the reflected light reaching the pinhole is defocused and the intensity decreases. A signal is only generated when the intensity of light going through the pinhole reaches the maximum.

Laser triangulations sensor
A laser spot is projected perpendicular or in an angle onto a target surface. The detector (receiver) is located at an angle relative to the laser spot on the surface (Emitter). A change in height on the surface in z causes a change in x on the detector. The internal controller automatically adjusts the exposure time based on the surface reflectivity.
