Technologies

Telecentric Laser Projector (TLP) provides parallel non angular laser line illumination as opposed to conventional lasers lines that projects a diverging fan.

The TLP has the advantage of reducing object occlusions on your image plane critical for 3D high precision structured lighting applications. In these applications the TLP evenly illuminates the complete part under inspection in order to achieve the measurement accuracy required.

Another advantage of the TLP is that its thickness is constant over its entire length. In applications such as semiconductor inspection, it is very important to have micron thin line over the entire length. With conventional fan out laser lines it is not possible to have both a thin line over a wide field due to depth of focus limitations. With the TLP, its parallel non angular illumination design allows for constant micron thin lines over large field of views.

Modulation

The Telecentric Laser Projector can be modulated by an external 0 to 5V external signal through the white wire. The S type modulation is included by default with the Telecentric Module.
