Optimized Solutions for Underwater Optics Design
Underwater optics play a crucial role in the design of underwater camera lenses, where a large number of variables come into play. As with every optical system design, the selection of cameras, lenses, housings, and operational parameters greatly influences the performance of the complete system. Determining the correct combination of components is what experienced optical […]
Understanding Radiometric vs. Photometric Data in Lighting Design
In the world of lighting design, we encounter a variety of metrics that describe the performance and effectiveness of a light source. Recently, we had a customer provide an illumination specification in watts, which is a radiometric unit, but for applications involving human vision, such as architectural lighting or display technologies, optical engineers typically work […]
RXI Collimators explained
Optical RXI collimators, also called non-imaging concentrators are optical components that can collect and project light from a source. Common examples include solar collectors that concentrate the sun’s light and project it to heat a surface or direct it to solar panels. Another application is to control the hemispheric radiation of an LED. Non-imaging concentrators […]
Design considerations for microlenses and lensarrays
As optical systems are reduced in size, we encounter new engineering challenges when analyzing and designing lenses. These are issues that we usually don’t see when working with larger elements. This article will review some of the challenges when designing microlenses. A small lens is roughly defined as a lens with a diameter lower than […]
