Agilent/Keysight E1834Z

The Keysight E1834Z is a mounted beam delivery optic designed for precision laser beam routing in interferometer and transducer systems. This fixed vertical-bend unit uses BK7 glass optics housed in 416 stainless steel to achieve exceptional pointing stability across demanding optical setups. The component redirects laser beams along a defined optical path while maintaining tight angular tolerances critical for high-accuracy measurements.
