WebA lens system subjected to a laser beam absorbs heat which causes thermo-elastic distortion, thermo-optic OPD efects and stress-optic OPD effects (see Figure - Lens system). The SigFit files were passed to CODE V for system optical analysis. The contribution of each effect is shown as CODE V output (see Figure - System Wavefront). Lens system WebHow to Analyze an Optical System This article will introduce how to analyze the optical system, such as to show a visual representation of the system, and then focuses on the Spot Diagram, OPD Fan and Ray Fan analyses, to evaluate the system aberrations.

WebIn optics and especially telescope making, sagitta or sag is a measure of the glass removed to yield an optical curve. It is approximated by the formula , where R is the radius of curvature of the optical surface. The sag S(r) is the displacement along the optic axis of the surface from the vertex, at distance from the axis.
