Everyone is on the path of shorter, less costly development cycles. Deciding on the most efficient path needs to be carefully considered. Is what appears to be the shortest path really what it promises?
In your next machine vision illumination project, you might want to consider optical modeling as a first step. Engineering services like optical modeling may benefit you more than you might think. Engineering services are often thought be expensive and time consuming. The truth is for certain kinds of challenges, optical modeling is quick and cost effective.
Optical modeling is ideal for making design choices among several options. When it comes to simulating the shape and uniformity of an illuminated field of view, optical modeling can't be beat. You don't need to determine absolute requirements, just make the educated best choice in a pool of several illumination alternatives. Several iterations of optical modeling can be done in a day. The tried and true iterative method.. now that takes time. Making chips doesn't exactly come cheap. When it's time to make chips, you want to be sure you are already far down the right road.
Optical modeling can uncover unexpected results. Optical problems are often non-intuitive. Periodically, one is caught by surprise in predicting how light will propagate in a system. Something as simple as predicting the result of Snell's law in several media and odd geometries can be an intellectual exercise. You only need to be caught off guard once to know the value of modeling.
If you are note sure how something is going to work, turn to simulation tools. It might just be the least expensive thing you ever did.
