Virtual, Augmented and Mixed Reality, Autonomous Cars and Medicine are just a among the applications which require projection of patterns with very large angles (Standard Beam Splitters, Random MultiSpot, Multi-Lines, Homogenizers, Multi-Rings or other custom pattern).

HOLO/OR offers high-angle magnification modules, suitable for all wavelengths and made from Polycarbonate or Glass substrates. These modules are available for a variety of angles, magnifications and different price ranges.

Each module includes a pattern generating Diffractive Optical Element (DOE) and lens-system to provide magnification (without aperture clipping). These modules can be integrated into existing laser systems, with no built-in laser source that limits the customer to a certain wavelength and intensity.

HOLO/OR offers solutions for both rapid prototyping in plastic material, as well as mass production in plastic and glass substrates.
For many applications, the pincushion distortion of the projected pattern is not an issue. However, for applications where this distortion needs to be corrected, HOLO/OR can provide such correction for the plastic module.
