Hi Mark! Thank you very much for your TH-cam channel. You are correct, it's often confusing to get the optics design concepts. We are very fortunate to have to you talk about it. We'll be eagerly looking forward to have more and more videos. I'm forwarding this to all my design frnds.
Great videos to connect optics knowledge with a software. Thank you for sharing back your knowledge. Please kindly post : when is part3:Mobile phone lenses coming. Also Please cover A- Telecentric lenses along with use of features in Zemax system explorer like how to correctly setup AFocal system, telecenteric lens... B- please have video on Optimization tab features what each means and C- please go through Analysis tab on what each features mean. Thank you so much
With the likes of an air spaced doublet, do you actually need the large refractive index difference between the air and the glass? Or might you be able to use an intermediate index optically transparent medium like an immersion oil or Canada balsam to help reduce reflections? Perhaps a balsam type cement would also mechanically secure required placement.
Well, add an index-matching layer between the elements and it becomes a cemented doublet, not an air-spaced doublet. But the power of a surface is (n2-n1)/R, so yes making n2 = 1 and n2 ~1.5 gives you a lot more power than using intermediate values
Hi Mark! I tried to make magnifying lens with the lens data on your video but the radius of the 3rd surface keeps changing to "Infinity" after I give the value -180.11|F. Why is that happening? Please help me.
@@marknicholson5508 I gave exactly the same values as in your data. Could you please tell me what was the aperture setting you gave? And also what is the value for F/# for Radius of surface 3?
PLEASE keep making these videos, you at least have one fan who will be clicking into each new one you release!
Thanks @Sean Fitzgerald, I'm working on the next one right now! :-)

Yes, exactly

Great help for beginners like me！
Great summary of all basic optics shapes. I really liked the explanation of when to use each optics.
Glad it was helpful!
Hi Mark, Thanks for the wonderful video. Can you please do a video on the design of microscope objective lenses?
Good Work Sir!
Great Sir.

Make sure you have put a glass on that surface

Hi Mark, thanks for these videos. Did you post Part 3: Mobile Phone Lenses? Thanks
Not yet...that one is coming. I really need to sit down and do more of these...
@@marknicholson5508 These videos are excellent, please continue. Thank you.
Is there readily available software to make lenses on a CNC machine (similar to how freeform spectacle lenses can be made)?
Try googling for Diffsys
Hi. This video are great! Can you add inverse telephoto lens?
I do plan to, once the Basic Shapes are done.
Hi Mark,
Student version of Zemax optics studio available??... i need work on Optics studio software
Yes there is! Please see www.zemax.com/programs/academic-program
