Freeform Optics For Imaging Mid Spatial Frequency Errors Webinars

Freeform Optics For Imaging Mid Spatial Frequency Errors Webinars Part 3 of the 2021 freeform optics series. residual mid spatial frequency (msf) surface errors are common byproducts of the computer controlled subaperture manufacturing techniques needed for fabrication of freeform optics. falling between “low frequency” form errors and “high frequency” surface roughness, msf “waviness” errors can. Part 3: " freeform optics for imaging: mid spatial frequency errors". miniature three mirror snap together freeform anastigmat (freeform tma). the optics were manufactured by the methods described in the presentation. a six inch scale is shown for reference. optical designers, engineers, those involved in the manufacture of optical systems.

Freeform Optics For Imaging Mid Spatial Frequency Errors Webinars Freeform optical surfaces have: 3 j m howard and s wolbach, “improving the performance of three mirror imaging systems with freeform optics,” osa freeform optics conference, 3 7 november 2013 3 mirror system shows up to 30 times improvement in system performance with freeforms, partially for larger field of views. One such challenge is the measurement of mid spatial frequency (msf) errors. the sub aperture polishing process used to make freeform optics inherently induces artifacts onto the optical surface. these artifacts are presented as tool marks or waviness in the surface figure. these mid spatial frequency errors can produce und esired. Mid spatial frequency (msf) errors can be a source of small angle scatter or blur in an optical system. this webinar will provide an introduction to msf errors. it will cover many questions optical designers often ask of optical fabricators, for example: what causes msf errors on the surface of optics?. In the last 10 years, freeform optics has enabled compact and high performance imaging systems. this article begins with a brief history of freeform optics, focusing on imaging systems, including marketplace emergence. the development of this technology is motivated by the clear opportunity to enable science across a wide range of applications, spanning from extreme ultraviolet lithography to.

John filhaber. when it comes to high performance optical systems, mid spatial frequency (msf) errors can affect applications in a wide variety of ways. for example, when present in cinematography optics, msf errors can dramatically affect the quality of the "bokeh," especially when the msf is present on aspheres (bokeh is the esthetic quality of an out of focus blur). Freeform optics offer great flexibility in design parameters, but the subaperture techniques required for manufacture often result in mid spatial frequency (msf) errors that can impact final performance. these errors must be removed, but the options to do so, often requiring hand smoothing by a skilled artisan, are costly and time consuming. optimax has developed the hermes (high end robotic.
