LED projection structured light for 3D reconstruction and dimensional measurement
LXV-2STL is a C-mount LED projector for structured-light 3D imaging. It accepts line, cross, stripe, grid, spot, spiral and round-stripe pattern chips, and the source documents a lighter upgraded body, sharper pattern projection and 50% higher brightness than the earlier STL series.

3D reconstruction
Project a coded geometry that a camera can use to recover surface shape.
Coplanarity and height
Read line displacement across terminals, steps and raised features.
Volume measurement
Project a line across an object to recover its section and volume.
Calibration and component dimensions
Use a known line or grid with the selected lens for machine calibration, mapping and electronic-component measurement.
Measured brightness, four application results and seven verified pattern geometries
The PDF evidence is separated into readable modules: application results, the 2STL-versus-STL line comparison, and the seven available projected forms. Labels and numerical pattern limits are rebuilt as native text in the selection tables.

Match the pattern, projection lens and working distance as one optical system
The light body is only one part of the projection geometry. Use the pattern requirements and lens table together before fixing working distance.
- 1
Choose the pattern
Select line, cross, stripe, grid, spot, spiral or round stripe.
- 2
Choose 5 W or 10 W
Match output and housing diameter to the working setup.
- 3
Select the projection lens
Use magnification or focal-length rows for the required spot.
- 4
Validate the camera result
Check line width, contrast and calibration on the actual target.
