Wondering if anyone has any experience with these Newport 935 series high power variable attenuators? Reading the description, they don’t exactly sound like the 930 series beamsplitters.
A completely unnecessary and redundant accessory...the output of any ion laser can be varied with excellent precision merely by varying the tube current. An infinitely more useful tool is a variable beamsplitter, for adjusting the object-to-reference beam ratio.
