Machine vision cameras come in different sizes and shapes. They are available in various resolutions and countless sensor formats. Choosing the very best lens can become quite a tricky task. You would need to choose out of hundreds of projects so making a mistake is always possible if you do not know what to do. 

The very best machine vision lens for you is not the same one for another project or another application. You will have to make the best choice or the result will not be ok. Your lens would practically be unusable if it is not the perfect fit. Always consider the following tips for a good choice. 

Choosing In The Correct Order

Very common mistakes can be mentioned when referring to how to choose the very best machine vision lens. One of those you have to know is that scientists or engineers so often first select sensors and cameras. Then, they choose their lenses. Never make this mistake because it can lead to the unwanted scenario in which the lens you buy is not optimized for your application. 

Image Quality Matters

In order for the machine vision system to create a quality measurement, the image used has to be of the highest possible quality. Image quality can be considered as being a critical determinant as you choose the best lens combination for your project. 

In the vision system, the lens choice also impacts other very important factors like achievable speed, measurement accuracy, reliability, and reproducibility. Downstream analysis is necessary and has to be performed at all times. 

Identify Application Needs

The selection process has to include application needs identification. Also, the selection process has to agree to key specifications. This comes under the form of parameters, which usually include things like resolution, working distance, depth of field, and field of view. When you know all of these, you will notice that the process of choosing the best camera and lens is very easy. 

The Sensor Matters

Remember there is a clear relationship between the sensor being used inside the camera and the very best lens you could use for the machine. You have to know sensor size to select the lens capable of illuminating all the pixels in the sensor area. A failure to do this will lead to vignetting and shading. The lens you choose should also be completely capable of resolving sensor pixel sizes. If the optical resolution of the lens is of a higher quality, the machine vision analysis result will offer better details. 

Customer Reviews

The internet made it a lot easier for us to choose the very best machine vision lens for our projects since it gives us access to reviews. After you make a list of the lenses you think are the best, it is a very good idea to simply look for customer reviews. They are going to tell you information you do not have access to from professional reviews you read online. Based on the customer reviews and the factors mentioned above you can make the best choice.
