Diffractive Optical Elements: Reducing Zero Order and Improving Diffractive Efficiencies

Diffractive optics have made it possible to effectively shape and split beams. They are lightweight and compact and can be easily integrated into optical systems. Also, they can perform many optical functions in one element. Diffractive optical elements (DOEs) have gone through advances that made them a standard component in laser material processing, structured light projection systems, as well as medical and aesthetic lasers. Improvements in DOE design and manufacturing processes have minimized undesired orders and zero order while enhancing uniformity and achieving higher diffractive efficiencies. How Do DOEs Work? These diffractive microrelief patterns manipulate the phase of an incoming laser beam to create a desired intensity profile in the far-field. Thus, they are characterize...

The Many Benefits Of Using Mask Sheets As Part Of Your Beauty Routine.

We all lead very busy lives, and many of us live in towns and cities where our skin has to put up with increased pollution, and increased temperatures.

Thankfully, for those of us who don’t even have the time to sit down on a chair for a moment, we can now use face masks as part of our moisturising and beauty routine. Deciding to use a whitening mask sheet (known as แผ่นมาร์คหน้าขาวใส in Thai) is the perfect way to treat your skin, to some much-needed help. When you choose ...
