A wavelength detector includes a beam splitter block that taps off two spatially separated beams and a linear filter in an optical path of one of the two beams. The linear filter may be provided on the beam splitter block. The linear filter may be a notch anti-reflective filter in the optical path of the application beam. One or both of the beams may be focused on to their respective detectors.
