These ranges may vary depending on various factors such as optics size and metrology instruments.) In this paper, we present the effect of polishing time and polishing interface material on ... Webirregularity by assigning tolerance operand TEZI which is simulating surface by adjusting Zernike coefficient. 0.00005mm is used as RMS surface irregularity. Fig. 6) Tolerance input to the Zemax Fig.7) Tolerance analysis routine in Zemax After completed to define tolerances, the Zemax will generate tolerance table in Fig. 8). Then we can run
WebThe impact of surface irregularity on Strehl ratio is also dependent on the f/# of the lens. As a general rule, faster aspheres, or aspheres with smaller f/#’s, have greater sensitivity to surface irregularity’s impact on Strehl ratio. For example, Figure 4 compares an f/2 lens to an f/0.75 lens (both with 25mm diameter), and more Strehl ... WebAug 26, 2012 · The effect of surface irregularity on Strehl performance - posted in ATM, Optics and DIY Forum: We often talk about the importance of a smooth figure on a telescope mirror. To understand that requirement better and how it relates to Strehl performance, I came across a nice little article recently posted by Edmund Optics in their resources …
WebA new ray model is presented for the reflection of electromagnetic radiation from the rough air-material interface of a randomly rough surface. Unlike previous derivations that modeled the rough interface as consisting of microareas randomly oriented but flat (facets), this derivation models it as consisting of microareas not only randomly oriented but also … WebA simplified theoretical model has been proposed to predict optical parameters such as thickness, thickness irregularity, refractive index, and extinction coefficient from transmission spectra. The proposed formula has been solved for thickness and thickness irregularity in the transparent region, and then the refractive index is calculated for the …
