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 107 and an accuracy better than 2 in 106 have been achieved.
