Unlike laser sources, which typically show poor line sharpness and power distribution inhomogeneity as well as scattering and diffraction effects, LTPR pattern projectors overcome all of these problems by integrating LED sources and precisely engraved masks.

Any kind of pattern shape can be easily supplied, integrated and projected by these devices.

Different colors, including UV and IR, are available and the size of the projection area can be easily modified by interchanging the projection optics.

KEY ADVANTAGES

Perfectly sharp edges
LTPR series ensures thinner lines, sharper edges and more homogeneous illumination than lasers.
With laser emitters the illumination decays both across the line cross section and along the line width; laser emitters are also thicker and exhibit blurred edges, diffraction and speckle effects are also present.
