See section our Product Guide for general recommendations ... Monday, 10 December 2007 24. What is the precision of FrontSurfer wavefront sensor? (FAQs/Wavefront sensors) Typical configuration of the FrontSurfer wavefront sensor has a precision of about λ/60 PV (for λ=0.63 ?m) in the reference mode and about λ/6 PV in the absolute measurement mode. ... Monday, 10 December 2007 25. What is the sensitivity of FrontSurfer wavefront sensor? (FAQs/Wavefront sensors) Typical configuration of the FrontSurfer wavefront sensor has a noise-limited sensitivity of about λ/60 PV (for λ=0.63 μm). The sensitivity can be improved by averaging over multiple frames ... Monday, 10 December 2007 26. What is the reference measurement mode of FrontSurfer? (FAQs/Wavefront sensors) In this mode, the wavefront is reconstructed from two intensity patterns captured by the wavefront sensor. The first one (main pattern) is measured in presence of the the aberration to be reconstructed, ... Monday, 10 December 2007 27. What is the absolute measurement mode of FrontSurfer? (FAQs/Wavefront sensors) In this mode, the wavefront is reconstructed from one intensity pattern captured by the wavefront sensor. Geometric parameters of the Hartmann mask or microlens array are used as a reference. This mode ... Monday, 10 December 2007 28. How many measurements are required for FrontSurfer to reconstruct a wavefront? (FAQs/Wavefront sensors) One in the absolute measurement mode and two in the reference mode.
