In industrial production, visual inspection systems play a very important role.As a key component of the visual inspection system, the performance and applicability of industrial lenses have a direct impact on the accuracy and efficiency of the entire system.Industrial lenses come in a variety of different focal lengths, each of which has its own specific applicable scenarios and uses. This article will introduce the features and uses of industrial lenses of different focal lengths.

Industrial lenses can be classified according to multiple factors such as focal length, aperture, imaging size, etc. Among them, focal length is the key factor that determines the lens field of view, magnification, shooting distance, etc. Common industrial lens focal lengths include 35mm, 50mm, 75mm, etc. Lenses with different focal lengths have their own specific characteristics and usage scenarios.

1. The 35mm industrial lens has a wide field of view and is suitable for detecting objects with a wide range. Due to its shorter focal length, it can better adapt to the needs of close-range detection. At the same time, it can image objects within a larger distance range, making the image distortion smaller, and is suitable for high-precision detection of round objects.

2. The 50mm industrial lens has a moderate field of view and is suitable for detecting medium-sized objects. Its focal length is moderate, which can obtain sufficient magnification within a certain distance while maintaining small image distortion, and is suitable for high-precision detection of objects of various shapes.

3. The 75mm industrial lens has a narrow field of view and is suitable for detecting smaller objects. Its long focal length makes the image distortion smaller and can obtain high-quality images. At the same time, it can image objects at a longer distance, which is suitable for detecting objects with high requirements for details.

Industrial lenses with different focal lengths have their specific characteristics and uses. Choosing the right lens can improve the accuracy and efficiency of the visual inspection system. In practical applications, it is necessary to comprehensively consider multiple factors such as the specific detection object, detection accuracy, and shooting distance to select the most suitable industrial lens.
