This course has a lot of potential, but leaves a lot to be desired. It’s definitely not for everyone, so take a few things into account before you join:

1) The lecture videos are pretty superficial. You can read the majority of the information in the first few chapters of pretty much any textbook on optical engineering.

2) There is a large discrepancy between the depth of information presented and the depth required to solve the assignments. Solving the assignments can often require a significant amount of time researching on the internet or in other optics sources to find the necessary background information.

3) Many of the assignment problems are very poorly written. Questions and explanations are ambiguous or unclear more often than not. I often had to solve the problems 2-3 different ways using a different interpretation of the question to get the right answer.

4) There is no interaction between the teachers and the course whatsoever. The forums are full of posts by confused students asking for help with 0 replies. Even now, well over a year after the course was created, the final assignment has technical issues that prevent students from even submitting the assignment as intended.

Issues #2 and #3 wouldn’t be critical if #4 were remedied, but the creators seem to have no interest in maintaining their course or interacting with the students in a meaningful way. In short, if you are looking to be dropped in the deep end of optical design and are an effective self-learner (seriously, you are on your own here), you can learn a lot simply by grinding through the assignments. If you are looking to be taught in the traditional sense, or for professionalism, look somewhere else.

I am still struggling through this course. The lecture materials are insufficient. The instructors are non responsive and the other students taking the class are too few in number for me to have a cadre with which to discuss. I'm left googling the topics in order to proceed. For the money spent, this is unsatisfactory. I'd highly recommend NOT taking this course.

Very poorly designed course. No one to ask or clarify requirement if you have any question. Project submission is such a mess that a lot of information can't be uploaded. Project instruction keeps telling you to save the file while a trial version that can't save any file is provided. Few peer to review assignment. This course just needs tons of polish before it's a good experience to go through. It's helpful to learn the knowledge but the process of studying is such a pain

I appreciate the content of the course, however, it is not meet my expectation. I did the the questions and most of the questions is pulling my attention on numerical calculation rather than understanding the optics principle. It is wasting of my time on those calculation rather than understanding the optics design. I would highly recommend the teacher think deeply and carefully to assign the homework and questions which would reflect to the value student paid rather than coping the questions from his/her real class or somewhere, good questions are really important for student to understand and digest the knowledge.

Good Course but it is impossible to get any response from the Instructors or TAs and the fact that we were using demo version of the Optic Studio which had some limitations in comparison with the regular version (like number of decimal places displayed, lack of optimisation wizard, inability to save your work) and needed to be reinstalled every two weeks or so felt very unprofessional.

there were so much missing information, so I took the first test and the questions were not that much related to what I got through the lectures

Fantastic intro to optics as a field. I'd recommend:

* Knowing a fair amount of trigonometry beforehand

* Reviewing matrix multiplication

* Time. You *must* understand how much time each concept takes to sink in, and you need to give it appropriate breathing room. Without that, it's very difficult to do well.

Could be less academic and more industry oriented.

I really enjoyed taking the course. Completing assignments especially after week 3 took me 2-3 times longer than the suggested specified time. However I learned a lot from this course.

Learning Zemax was always like a hurdle for me but amazingly the instructor walked me through the main features of the software and I feel you already know a lot about optical design and simulations.

The capstone project seems to be tough (I haven't started it yet), but it is worthed spending the time since it complements your learning and proficiency level.

Learned a ton about paraxial optics design. Great lecture, capstone project is A LOT of work (>20 hour) for me.

Sometimes the lectures didn't contain enough info to do the homework. But the lectures and the homework were both h

Very advanced, and might be intractable for those without some previous optics experience.

The course is very good and has a high level - it can be quite demanding at times. The classes are neat and instructors very didactic. What is a little bit upsetting is that the instructors rarely check the discussion board... interaction there is very low even with other students, which can make learning a little bit harder...

This course is by far the best I have followed in Coursera. The material is highly interesting and, contrary to many others, the quizzes require you to think and take a little time to work out the solution. Disregard comments about the grading system being flawed. There are very few cases where there is ambiguity on the question and you can resubmit your answer immediately, so that will not delay your progress in any way. All the information you need to solve the problems is contained in the videos, and for the very few occasions when an external source is needed you are directly pointed to it. It's all pretty much self-contained. If you are looking for a quick certificate with no thinking or effort required, go somewhere else. On the other hand, if you really want to learn you can't go wrong with this course.

This course is an excellent and concise way to get acquainted with basic (paraxial, paper-based) optical design. I've been on a quest to self-study to becoming an optical designer and I've been looking for something like this - this is the course that addresses the gap in many an optical engineering text book. The assignments also necessitate some critical thinking and further study. The course is more involved than the overview would have one believe!

A unique and very well designed online applied optics course which provides insight to optics designing and helps in understanding the optical systems. After this course, i feel enriched with the optics knowledge. Anxiously looking forward for more courses in this specialization.

Pretty much intuitive and quite sort of pushing up was involved throughout the course. I tried hard to get the most as much as possible out of it. Practices and tasks, all assignments, are well preparing one for the optical design industry

Very well delivered lectures - explanation of concepts are done methodically. Recording of and presentation of lab experiments were good and to the point. Assignments were challenging but well within the grasp of subject taught.

Thank Professors for the informative course that forces us to deal with some practical design systems. Some problems needed extra knowledge that not taught here and we should search for them in more detail.

Really nice course with very clear explanations of the principles of optical engineering and learn how to use ZEMAX Opticstudio to simulate your optical system

An excellent course that teaches you geometric optics and gets you started with ZEMAX. Some of the quizzes have typos/bugs in them, but this is a minor gripe.

Good course, explanations are clear and concise and I got a good learning. Tricky exercises! Perhaps more exercises with quantstudio would have been nice.

A few new insights even for a senior optical engineer. I will keep working through their lectures if each one offers at least a few nuggets of insight.

Wonderful course! I have learned a lot. This course not only covers the knowledge but also the actual approach to design a working optical system.

The course is well structured. it would have been much better if there was more zemax design model in the weekly quiz.
