![]() ![]() High quality optical parts as found in any professional microscope.Even small kids can easily use it on their own. You can simply use your smartphone screen to view the enlarged image and click pictures and videos. It's great fun to use and has an amazing educational value for kids, students or teachers. It's a complete redesign of the classical field microscope. Because of these benefits, telecentric optics are built into highly reliable devices like the DSX1000 digital microscope.Ī microscope equipped with a telecentric optical system can streamline the inspection process since you won’t need any extra cameras or equipment to fix the magnification changes.It's a small optical microscope specially designed for Smartphones. In addition to eliminating parallax errors, telecentric optics also tend to have a larger depth of field and lower distortion than conventional optics. Telecentric optics, however, help ensure a high degree of accuracy and repeatability. Not only can the perceived size of objects change, but objects closer to the lens could block other objects from view. This perspective error-or parallax-can make it challenging to produce accurate, repeatable measurements. If you’re trying to measure a large, three-dimensional object with a conventional lens, the measurement results from the top and bottom of the object might read differently. Microscopes with conventional optics cannot deliver the level of accuracy needed. In many applications, such as the aerospace and automotive industries, inspectors must make precise measurements from microscope imaging. In everyday photography, a conventional lens works just fine for capturing high-quality images.īut microscopy is another story. If you image railroad tracks with a telecentric lens, the rails look the same distance apart. Now imagine you’re trying to measure a very small critical component using your microscope and you can understand why telecentric optics are so critical to accurate measurements. Since telecentric lenses reduce or eliminate the magnification changes, the image reveals the precise size of the tracks. ![]() In this case, the tracks remain the same perceived size regardless of whether they are closer to the lens or farther away. ![]() Now let’s say you take the same image using telecentric optics. You know that the tracks stay the same distance apart throughout its entire length, but, in the image, the tracks appear to come closer and closer together as they go off into the horizon. Let’s say you take a photo of railroad tracks using a conventional lens. Here’s an example to illustrate the difference. So, what does an image captured with a telecentric lens look like compared to one captured with a conventional lens? This angular field of view is also the way we see the world around us, and it helps us perceive depth. With entocentric lenses, closer objects will appear larger than those further away. Most conventional lenses are entocentric. Conventional lenses can be either entocentric, where objects further away have lower magnification, or pericentric, where objects further away have higher magnification. The impression of spatial depth in the image appears flat, so objects at two different working distances will remain the same perceived size.Ĭonventional optics, on the other hand, are lenses with an angular field of view that exhibit varying magnification for objects at different distances from the lens. Telecentric optics are lenses that provide the same magnification regardless of the object's distance or location in the field of view. Today’s blog post will clear up any confusion on the topic and explain why telecentric optics are so important. Despite this, many people remain unsure of what telecentric optics are and what they’re used for. Telecentric optics provide many advantages compared to conventional optics, particularly when it comes to industrial inspections.
