LTPRSMHP3W series are LED pattern projectors specifically designed for the most demanding 3D profiling and measurement applications. Triangulation techniques require that structured light is directed onto a sample at a considerable angle from vertical. Tilting the light source pattern becomes essential to ensure that the patterned light is properly focused across the entire sample surface.

The projection area shown in the chart are also a good approximation for standard C-mount lenses used as macro lenses (eventually equipped with spacers).

With non bi-telecentric lenses, a square pattern becomes a trapezoid in the projection plane, whose parallel sides are indicated as “w” and “W” in the drawings below.

The projection pattern placed inside the unit can be changed and integrated with ease: just remove the C-mount adaptor by loosening the set screws and fix the pattern by screwing the retaining ring.

Standard Lenses (35-70mm). Standard lenses, often referred to as "normal" lenses, have a focal length that ranges from 35mm to 70mm.

Excellent results can also be obtained with zero distortion macro lenses; here, the magnification changes along both axes, but image resolution and distortion still easily allows 3D reconstruction.

LTPRSM series units can be interfaced with any type of optics, but the best results are achieved with bi-telecentric lenses. The projection area is undistorted since tilting the pattern causes a linear extension along only one direction.

LTPRSMHP3W pattern projectors integrate a precision tilting mechanism based on the Scheimpflug condition. This ensures that focus is maintained across the entire part, and reconstruction of the 3d surface is as accurate as possible. Moreover, the internal focus mechanism offers the maximum optical throughput.

When these features are projected, they become 1/M times larger, with “M” being the magnification of the projection lens. The number of lines mentioned after each part number indicates the number of features on the active area of the pattern.
