_______UPDATES ________



Update, December 6, 2017: New! Sample files from the book are now provided in the Zemax OpticStudio 17.5 release. Check out the release notes HERE

Update, January 4, 2018: A brief explanation is provided to justify an assumption made in Sec. 3.3.1 concerning image magnification in the human eye (taking into consideration the refractive index of the medium in the eye). Download the update HERE.


Update, January 13, 2018: I've written a short technical note discussing a concept where variable focus without any moving parts may be achieved by scanning a liquid crystal shutter across a stationary progressive powered lens. Although the paper is separate from my book, it is highly relevant to modern optics and imaging, which is indeed the spirit of the book. 


Update, January 22, 2018: An explanation is provided to justify the one-dimensional Fourier transform performed in rectangular coordinates for Eq. (2.51) on page 71. Download the update HERE.


Update, February 20, 2018: An explanation is provided for why the position of peak irradiance (POP) for a lens component or lens group within a complete optical system may be different from the location of the aperture stop of the entire optics system. Download the update HERE.


Update, March 11, 2018: An explanation is provided for how to relate the Gaussian apodization factor G to the plane of the aperture stop for the resolution enhancement discussion in Sec. 2.2.2.3. Download the update HERE.


Update, June 5, 2018: I am thankful to a reader who has alerted me that there is a broken link to the article cited in Ref. 98 (in Sec. 3 of the book) titled, "Analysis of Biocular Images using 3D Glasses and Zemax: A Plausible Approach." I have contacted Zemax and was able to obtain the original article, which is now available HERE for download (it appears that the link at Zemax is being moved as they transition to a new customer portal).


Update, August 15, 2019: In Sec. 3.3.4, "Spectrometer mobile phone attachments", I discussed some basic principles of spectrometers in the context of converting a handphone into a handheld spectrometer, but I did not mention about the need to obtain the spectral response of the image sensor. Click HERE for a short remark concerning this (and a short note on the difference between spectral response and quantum efficiency).

Update, December 25, 2020: In Sec. 3.2.3.3, "Telecentricity does not imply uniform relative illumination", I discussed techniques to control the relative illumination of a lens system. I also showed how to inspect the entrance and exit pupils of an optical system by tracing rays from the aperture stop in two directions. But today, I have found a better technique, which does not require creating separate lens files to trace rays from the aperture stop. Click HERE to read more about it!
