Coherent's Flat Top Projector provides true flat top performance with no compromise. It offers very smooth spatial variations with very low ripple, unlike other technologies that use overlapping creating unwanted high frequency interference noise.
In combination with conventional optics and Coherent’s vast array of beam splitting DOEs a wide variety of patterns can be projected very efficiently. The flat top optics is all glass with losses due to reflections only. Using AR coatings, efficiencies of over 98% can be achieved giving you all the power where you want it.
