An automated system for selecting optical apparatus compares a set of user specifications with the optical characteristics of a plurality of standard optical components, and automatically chooses a combination of the components forming the closest match to the user's requirements. The method is performed using a programmed computer which may be remotely interfaced with the user via the internet. The user inputs the specification into the computer using a standardized input table. The user may optionally specify that the system be designed using a particular product line or family of standard products. If a system exactly matching the customer's specifications cannot be found, two systems are suggested that bracket the customer's stated requirements.
