Coherence condersor lens
WebA condenser lens collimates the light from the broadband light source. A beam splitterseparates the light into reference and measurement beams. The reference beam is reflected by the reference mirror, while the measurement beam is reflected or scattered from the test surface. Weblens is much smaller than the lens area: (13.3) The lens aperture can then be viewed as an incoherent source as well. Let’s examine this in detail. The source is assumed to be …
