Retinoscope Design
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...
了解客观镜头
引言在先前的条目中，我们讨论了扫描显微镜的设计，无限校正的显微镜，共聚焦显微镜设计和Koehler照明系统 - 显微镜中的常见照明系统。最重要的显微镜元素...
Powell Lens Design
Previous posts have reviewed different techniques for beam homogenization as well as the difference between spot size and beam angle. This post will review a method for beam shaping using Powell Lenses. Powell lenses are lenses that create a straight laser line by...
Conoscopic Lens Design
圆锥形镜头是一种可用于测量光源角度分布的仪器。它的用途与镜头完全不同，就像摄影一样。由圆锥形镜头创建的图像类似于鱼眼镜镜的图像。这是一个...
Tessar Lens Design
Among the many lens design configurations, one of the most common lens optical layouts is the Tessar Lens. This layout was created by Paul Rudolph in 1902 for photographic lenses. In the golden age of film photography, the...
Projection Lens Design
Projection systems are one of the most common consumer optical devices (probably second to photographic systems). They allow us to view images on a screen (usually) by magnifying and projecting them at distances from a few centimeters to several meters away...
Apochromatic Lens Design
在出色的镜头设计中，我们优化了两个波长，通常是红色（590nm）和蓝色（495nm），重点放在同一图像平面上。这样做是为了减少色差。在本文中，我们将讨论类似的设计类型，称为An ...
How the Abbe Sine Condition impacts optical designs
进行一阶光学设计计算时，大多数工程师都使用基于近距离（或理想）系统的参数。也就是说，主要光线非常接近光轴的镜头。但是，情况并非总是如此，随着我们的移动...
F-Theta镜头如何工作（及其何时使用）
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...
LIDAR Lens Design
Not all optical systems require sharp images and low aberrations. While imaging systems use MTF, Strehl ratio and wavefront error to evaluate quality, there are other systems like solar collectors where there is no image formation and the goal is to maximize the...
Common telecentric lens design layouts
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...
5 Applications of Cylindrical Lenses
When thinking of a ‘lens’, most people have the image of a spherical lens in their mind, but there are different geometries for lenses. One very common geometry is that of cylindrical lenses. What’s the difference between spherical and geometrical lenses? And why do...
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...
Interpreting Lens Spot Diagrams
作为光学工程师，我们使用不同的工具和技术来评估在射线跟踪程序中模拟系统时的光学设计性能。其中一种工具是斑点图。他们一开始使用可能有些混乱，但是...
How Aspheric and Freeform lenses work
A key aspect of an optical product development is the creation of a quality optical system design optimized to reduce aberrations and system cost. In an attempt to reach a balance between cost and performance, optical designers have created lenses with different...
Zemax的黑匣子镜头的好处
将架子镜头集成到光学系统中时，必须拥有有关镜头在系统中其他元素的表现的完整信息。当涉及多个组件供应商（即电子，机械，光学）时，数据...
Scanning and Fluorescent Microscope Design Steps
显微镜是一种基本技术，用于分析太小的样品而没有放大的样品。它用于多个科学，从生物学，医学，化学到人类学以及小样本的任何科学...
用于步枪示波器的光学设计类型
秋天快到了，狩猎季节。在我的状态下，狩猎是如此受欢迎，以至于一个非官方假期，学校“取消”，国会获得休息一天。我不确定这是否发生在其他地方，但是可以说狩猎是很大的一部分...
出色的双重设计和优化
基本概念最常见的光学结构之一是色氨酸。它用于减少色差。从最基本的角度来看，它是两个镜头系统配置，其中一个透镜是凹形镜头，通常是由火石玻璃制成的，另一个是...
