In the last month, I have had the need to travel several times by airplane. So, after several hours enjoying $15 sodas, and $30 hamburgers at the airport gates, I started paying more attention to the different illumination systems that are being used in the aviation...
光学准直仪也称为非成像浓度器是可以从源收集和投射光的光学组件。常见的例子包括集中太阳光并投射其加热表面或将其引导到太阳能电池板的太阳能收集器。
这将是我们用于验光的光学仪器系列中的最后一个条目。如果这是您看到的第一篇文章，我建议您查看我们以前有关眼镜设计，角化仪设计和视网膜镜检查的文章。这个...
视网膜镜是验光师使用的一种非常常见的光学仪器，可检查患者的眼睛并评估纠正镜的需求。他们使用一个非常有趣的身体原理。让我们首先描述光学仪器。视网膜镜是手握的...
在本文中,我们将继续我们的描述of different optical instruments used by optometrists. Last time we talked about Ophthalmoscopes, today we will talk about another very common optical instrument called the Keratometer. The keratometer was developed...
In the next couple of articles, we will talk about the different instrumentation used by ophthalmologists and optometrists. As you can imagine, there are many restrictions when designing an optical instrument that will be used in a patient. It matters whether the...
This is our last entry on our scanning mirrors series. In this article, we will talk about the use of scanning mirrors when working with welding environments. As you can imagine, not only do the optical requirements differ when compared to those of a scanning...
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...
This week, we will continue our discussion of fast steering mirrors. If you missed our last article, go ahead and read about steering mirrors for laser marking. Here, we will discuss the design requirements for steering mirrors in Optical Coherence Tomography (OCT)....
在接下来的几周中，我们将讨论与转向镜（也称为扫描镜子）一起工作时的不同设计要求和限制。目的是向您展示不同的应用程序需要不同的解决方案，并且...
Introduction In previous entries, we have talked about the design of scanning microscopes, infinity corrected microscopes, confocal microscope design, and Koehler illumination systems-a common illumination system in microscopes. The most essential microscope element...
Endoscopes are medical devices designed to collect the smallest images from inside the human body. Endoscopes can be divided into two categories: rigid endoscopes, in which relay lenses are stacked together generally creating a high-quality image, and flexible...
When I was a young undergrad engineering student, I always found optics to be a very confusing subject. It was not only the equations, but what it looked like hundreds of different definitions involved in even the simplest of optical systems. Some concepts, like...
先前的帖子已经审查了光束均质化以及斑点尺寸和光束角之间的差异的不同技术。这篇文章将审查使用Powell镜头进行光束塑形的方法。鲍威尔镜头是通过...创建直线激光线的镜头
玻璃的选择是光学设计过程中的基本部分。IR和热光学材料尤其如此。在本文中，我们将讨论氟化钙（CAF2），这是一种有趣的玻璃，具有广泛的应用。
梁拆分器是光学系统中的基本元素。从本质上讲，光束拆分器是用于将单个光源（通常是激光器）分为两个单独的光束的光学组件。更常见的光束拆分器（您在大多数...中都可以找到的那种...
作为光学工程师，我们不仅负责用于特定应用的光学系统的设计和实施：我们通常需要评估光学系统的性能或评估光学组件的质量。进行这些评估，...
A conoscopic lens is an instrument that can be used to measure the angular distribution of a light source. Its use is quite different from a lens, as in photography. An image created by a conoscopic lens resembles that of a fisheye lens. That is a...
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...
在许多镜头设计配置中，最常见的镜头光学布局之一是Tessar镜头。这种布局是由保罗·鲁道夫（Paul Rudolph）于1902年创建的，用于摄影镜片。在电影摄影的黄金时代，...
