    50-mm-diameter fused silica Fabry-Perot etalon pairs with matching accuracies of > λ/200 are offered for ultra-high resolution interferometry. A new polishing technique reproducibly improves the spectral filtering capability (finesse) of the pairs. Parameters including material quality, optical figure, plate parallelism, and coating quality are all critical to the overall performance.
