In certain projects, the best lens design choice is not to do a design. While in volume, costs savings for a custom design are considerable, there are times when delivery time requirements don't permit the use of a custom design, or when a existing lens used in high volume for a different application can be re-purposed.
This process of finding the right lens starts with an online search off-the-shelf products and then (and this part is important) requesting Zemax 'black box' files. These Zemax files allow the optical engineer to truly model lens performance for a specific application.
