The power of close focus distance for zoom block cameras

When it comes to capturing detailed images from a shorter working distance, having a zoom block camera with a shorter close focus distance can make all the difference. Our 10x Autofocus Zoom Block Camera line with EX-SDI, HD-SDI, AHD, and CVBS  video output, has an extended version with an improved close focus performance. The camera can be set to a minimum focus distance of 10 mm (0.39”).

The firmware adjustment allows for a further decrease in the minimum focus distance setting from 100 mm (3.94 inches) to as low as 10 mm (0.39 inches) for a better close focus distance.

What is Minimum Focus Distance?

In our world of imaging solutions, minimum focus distance refers to the minimum distance at which the camera can focus and capture a sharp image of an object. Also, referred to as the "minimum shooting distance" or "closest focus distance", this represents the shortest distance between the camera sensor and the subject that can be in focus.

With a camera where the minimum focus distance is long, the camera will have to stand further away to focus on your object. In simple terms, minimum focus distance refers to the closest distance a camera can bring an object into sharp focus.

Why is Minimum Focus Distance Important?

Minimum focus distance is an important specification, particularly in applications where close focus imaging is required. This feature allows the camera to capture fine details of objects that are located at a very short distance from the camera.

So, why does close focus distance matter? Well, it determines how close you can get to your subject while still being able to capture a clear and detailed image. If you try to focus on an object that is closer than the minimum focus distance, chances are your camera will struggle to autofocus or produce blurry results. This becomes a pitfall especially if you are providing images from confined spaces. In these settings, you will inevitably be close to the subject physically, while maintaining the focus.

Our zoom block cameras are often used in a wide range of applications from quality control to robotics, and from medical imaging to machine vision. In all these types of similar applications, it is crucial to have the ability to focus on close objects accurately.

The introduction of close focus distance capability enables our zoom block cameras to capture clear and detailed images in many industrial inspection applications, such as in unmanned robots that are used for the inner side inspection of pipes. With the ability to focus at such a short distance, the smallest defects or abnormalities become visible and can be accurately analyzed even in small and tight spaces. In any situation where space is limited, you still have the ability to perform accurate analysis, inspections, and quality control for effective decision-making.
