Compact Fizeau wavemeter
Abstract
A Fizeau wavemeter using a sealed airspaced wedge is described. Off-axis geometry is employed to produce a compact instrument with good temperature stability. Calibration using a CW multimode dye laser and an argon discharge lamp is described. A precision of 2 in 10 to the 7th and an accuracy better than 2 in 10 to the 6th have been achieved.
