These high-performance mercury line filters are ideal for use with high-power mercury arc lamps for spectroscopy, optical metrology and photolithography mask-aligner and stepper systems. Maximum throughput is obtained by careful optimization fo the filter design to allow fo use in a variety of differnt applications. The non-absorbing blocking ensures that all other mercury lines as well as intra-line intensity are effectively eliminated.
