Key advantages

  • LED technology for perfectly sharp edges
    Thinner lines, sharper edges and more even illumination than lasers
  • 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
  • Repeatable results with dedicated strobe controllers
    Compatible LTDV series ensures very stable illumination intensity
  • Wide selection of projection patterns available (custom-made upon request)
    Chrome-on-glass patterns with geometrical accuracy down to 2 μm
  • Compatible with any C-mount optics

Notes

  1. With a 35 mm lens, F/N 1.4 at 100 mm working distance without projection pattern at maximum driving current. Estimated value.
  2. To directly drive the LED, current control is necessary. External compatible controller from LTDV series must be used.
  3. At 25°C. At max pulse width (1 ms), max pulse frequency = 15 Hz. Contact us to check other admissible combinations of duty cycle-frequency-temperature.
  4. At 25° C.
  5. Including connector.

LTPRUP pattern projectors can be easily integrated into any vision system thanks to their 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.

LTPRUP-x models for strobe-only operation featuring ~ 90W peak power intensity. These models are compatible with CMHO016 clamping mechanics, alternatively, three M4 and one M6 threads are available as fixing options.

Projection lens selection

Any C-mount optics for 2/3” sensors (11 mm image diagonal) can be interfaced with LTPRUP series to project areas with different sizes. 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 dimensions will be “M” times the original dimensions of the pattern, where M is the optical magnification at which the selected projection lens is operating.

Telecentric lenses for 2/3” sensors can also be interfaced with LTPRUP models, thus providing telecentric projection of the pattern and enabling unparalleled performance in 3D measurement applications.

Pattern selection

Pattern selection

The projection pattern can be easily interchanged by unscrewing the retaining ring that holds the pattern. The pattern outer diameter is 21 mm, while the active projection area is a circle of Ø 11 mm.

The pattern drawing could either cover the entire 11 mm diameter area or be of any shape inscribed within this area (such as a square whose side is 7.78 mm or an 8.8 x 6.6 mm rectangle). The projection accuracy depends both on the pattern manufacturing accuracy and the distortion of the projection optics mounted on the projector.

The edge sharpness of the projected pattern depends on both the lens resolution and the engraving technique: laser-engraved patterns (part numbers ending in “L”) or photolithography-engraved patterns (part numbers ending in “P”) can be chosen depending on the type of application.
