Tutorial on ISO 10110 Optical Drawing Standard

Tutorial on ISO 10110 Optical Drawing Standard Introduction Specifying optical components is a vital method for the optical designer to relay to the optician exactly what is expected to be produced. Without a standard method for describing the details of the part, there is no guarantee that the designer will end up with a part […]

Choosing vibration isolators for optimal performance.

Tutorial Selection of vibration isolators

Tutorial Selection of vibration isolators Abstract Controlling or isolating vibration caused by a ground motion or an acoustic noise is critically important in precise optical fabrications and measurements. There are two methods for controlling or isolating vibration, passive and active vibration isolation. The goal here is to compare passive and active vibration isolation and examine […]

Passive Athermalization of an Infrared Optical System

Passive Athermalization of an Infrared Optical System

Passive Athermalization of an Infrared Optical System Introduction This tutorial will cover the design of an athermal lens mount for an infrared double-Gauss objective. This objective will need to be able to survive a space environment. It will experience large temperature changes and needs to remain in focus so imaging can occur continuously. The lens […]

Precision control of optical systems. (Part2)

Tolerancing in ZEMAX 2

Tolerancing in ZEMAX Abstract Tolerancing is a very useful skill to have as an optical engineer. If an optical system is to be built, a tolerance analysis must be performed to ensure that the system will meet the performance specifications. Tolerances should be specified for any parameters in a system that might vary by some […]

Precision control of optical systems. (Part1)

Tolerancing in Zemax 1

Tolerancing in Zemax Introduction Being able to design a good optical system is important as an optical engineer, but equally as important is being able to tolerance it. Without this skill it is near impossible to bring any theoretical system that you have designed to reality. For simple systems consisting of perhaps one or two […]
