Creative Laser Production Lightworld Gratings
Glass MACHADO Transmission Grating 1" * 1" (25,4 * 25,4 mm)
The Machado Grating is the probably most exciting innovation since the development of the Machida-Grating.
Active Grating Area: 7 * 12 mm
Creative Laser Production has ready developed their first computer generated digitalgrating, the MACHADO. This LINE grating glance with its high effect angle and the extraordinary high density in orders, similar to the popular MACHIDA grating (Machida Inc. Tokyo), but much more economic in pricing.
The MACHADO comes on glas substrate (1 x 1 inch) with a usable beam aperture of 7 * 12 mm, excellent power rating of more than 7 Watts and good zero order suppression. The master relief structure has been calculated and optimized via CAD interferometric simulation and then directly inscribed in a chromium layer on glas with an electron beam lithograph. Special glas etching process in fluor vapor phase converts finally the chromium mask to a relief structure in glas.
Most of the masking processes are quite similar to production of ultrahigh scale integration semiconductor chips using state of the art technologies, which are quite sophisticated in their kind.
The MACHADO is an excellent tool to create artistic beam effects with hundreds of colored beams over a wide fan angle, which a scanner will never? be able to produce.
