HEDS - High Efficiency Double Spot Beam Splitter
DOEs for demanding and sensitive applications
Double spot beam splitters are diffractive optical elements (DOE) used for separating an incoming laser beam into two identical beams. They are most commonly used in lithography as well as high power applications such as cutting and perforation. Until now, a small portion of light was lost in higher diffraction orders, but there are applications that do not tolerate even a 1% loss. Therefore, Holo/OR has developed this DOE with an efficiency well above the standard value of 81%.
HEDS is very sensitive to centering. Slight changes have no effect on spot shape or overall efficiency, but will result in a different efficiency ratio between the two spots. Then again, with some skill, this may be used for achieving division ratios other than 50/50 – for example 47/53.
HEDS is available in wavelengths between 193 nm and 10.6 μm.
