LTPRUP series are the most powerful LED pattern projectors designed for fast image acquisition in high speed applications where camera exposure time must be set to the minimum, including planarity control of opaque products, robot guidance for fast pick and place and 3D profiling. LTPRUP are strobe only and provide ultra-high intensity while ensuring extended LED lifetime and reduced heat generation. LTPRUP series are current driven and can be precisely controlled using compatible LTDV strobe controllers series.

LTDV series is designed to drive the LED of LTPRUP pattern projectors with extremely constant current ensuring repeatable results even in applications where low exposure time is required minimizing illumination intensity variations down to ± 1%, leading to accurate and repeatable results when compared to models offered by major competitors. Additionally rise and fall time are kept to the minimum: this ensures repeatable results specifically in applications where light intensity is controlled through time-dimming.

Multiple interchangeable patterns, either stripe or grid styles, are available along with optional custom patterns. LTPRUP is easily integrated into any system thanks to its compact design, multiple threaded holes positioned in the rear part, and compatibility with CMHO016 clamping mechanics. Additionally the phase-adjustment design allows for easy pattern alignment.

KEY ADVANTAGES

  • Ultra high-power light output and strobe mode only operation
    Low sensitivity to ambient light for the inspection of fast moving objects and an extended LED lifetime.
  • LED technology
    Thinner lines, sharper edges and more even illumination than lasers.
  • Repeatable results with dedicated strobe controllers
    Compatible LTDV series ensures very stable illumination intensity.
  • Wide selection of projection patterns available
    Chrome-on-glass patterns with geometrical accuracy down to 2 μm.
  • Compatible with any C-mount optics

Projection lens selection

The pattern drawing which has to be projected must be inscribed in a 11 mm diameter circle, same diagonal of a 2/3” detector.

For example, the pattern drawing could cover the entire 11 mm diameter area or be like a 8.8 x 6.6 mm rectangle or, again, be a square whose side is 7.78 mm.

Unless the projection optics introduces significant distortion, the shape of the projected pattern will preserve the features and aspect ratio of the engraved pattern. The projected area size will be equal to 1/M, where "M" stands for the magnification factor of the lens when used as a standard viewing objective.

LTPRXP series can integrate high resolution C-mount lens for 2/3” detectors (11 mm image diagonal), using the mount adaptor included in the product package. Here is a list of the projection diameters and the recommended projection distances with different types of optics.
