3 Keys To Quality Double Gaussian Lens Design
by Victor Argueta | Nov 10, 2022 | FAQ, lens design, lens design consulting, Uncategorized
One of the most common lens system designs- especially in photography- is what is called a Double Gaussian lens. There are several different configurations, and close to 90 different patents have been filed from 1936 – 2010. One of the reasons this lens design configuration is so popular is that it corrects many of the major image aberrations with a relatively low number of optical elements.
Steering Mirrors In LIDAR Systems
by Victor Argueta | Feb 15, 2022 | FAQ, lens design consulting, Optical Components, optical engineering, Victor Argueta
This is our third installment of a four-series blogs about steering mirrors. We have talked previously about steering mirrors in laser markings and steering mirrors in OCT systems. This week, we will talk about the steering mirror requirements for those in LIDAR...
Calcium Fluoride Glass: An Overview
by Victor Argueta | Oct 28, 2021 | FAQ, lens design consulting, OFH, Optical Components
The choice of glass is a fundamental part in the optical design process. This is especially true for IR and thermal optics materials. In this article, we will review Calcium Fluoride (CaF2), an interesting glass that has a wide range of applications. Before we start,...
by Victor Argueta | Sep 7, 2021 | FAQ, lens design consulting
When designing any optical system, an optical engineer needs to consider how illumination will be used: specifically, how the illumination could affect the way the image is created. If not carefully designed, some illumination systems may create a kind of...
Fisheye Lens Design
by Victor Argueta | Jun 11, 2021 | FAQ, illumination, lens design consulting, optical design
Anyone who has peaked through a hotel room peephole has used a fish eye lens. Usually, the fish eye lens has a very short focal length (less than 15mm for a 35mm-size image sensor), but a large field of view (FOV). The latter can be as large as...
Apochromatic Lens Design
by Victor Argueta | May 17, 2021 | FAQ, lens design, lens design consulting, optical design, optics definitions
In an achromatic lens design, we optimize such that two wavelengths, usually red (590nm) and blue (495nm), focus on the same image plane. This is done to reduce chromatic aberration. In this article, we’ll talk about a similar design type called an Apochromatic lens...
Optical Design Considerations for Underwater Optics
by Victor Argueta | Apr 27, 2021 | FAQ, illumination, lens design consulting
The design of an underwater camera lens can be challenging due to the large number of variables at play. As with every optical system design, the selection of cameras, lenses, housings, and operational parameters greatly influences the performance of the complete...
How F-Theta Lenses work ( & when to use one)
by Victor Argueta | Mar 31, 2021 | lens design, lens design consulting, machine vision
In a scanning system, a laser beam moves linearly in one or two dimensions by usually using a galvanometer or scan mirrors. The focused laser can then be used for engraving images in different materials, and drilling, cutting or other applications. However, when...
Common telecentric lens design layouts
by Victor Argueta | Mar 18, 2021 | FAQ, lens design, lens design consulting, machine vision, optical engineering
What is a Telecentric Lens ?An important goal in machine vision applications is taking measurements in a consistent, accurate, and precise manner. This can include measuring the dimensions of manufactured parts to guarantee they are within the...
Explanation of 4f optical systems
by Victor Argueta | Jan 6, 2021 | lens design consulting, OFH, optics, optics definitions
A 4f correlator optical system is a system architecture that uses Fourier Optics. In this article, we will explain why we need them and how to design a simple 4f correlator. We will leave out most of the mathematical derivations, but if you are interested...
Fundamentals of Relay Lens Design
by Victor Argueta | Dec 3, 2020 | FAQ, lens design consulting, Zemax
A common optical system is relay lenses. Relay lenses are used when the user cannot be physically close to the object being observed (like an endoscope) or when images need to be inverted/rectified (like in a telescopic sight). Here we describe some steps that...
Understanding diffractive beam splitters
by OlegRybakovsky | Jul 5, 2019 | lens design consulting
Diffractive beam splitters A diffractive beam splitter is a diffractive optical element (DOE) used to split a single collimated laser beam into several beams with the same optical characteristics as the original beam. Beams are usually separated into 1D or 2D arrays...
Hiring a lens designer
by John | Apr 30, 2019 | lens design consulting
Planning to hire a lens design partner to assist with your optical engineering program? Here are a few things to consider. Do you need a lens for illumination or for imaging? The design methods and software tools used for illumination and imaging are different. Many...
