As a key component in the machine vision system, industrial inspection lenses are available in a wide variety to meet different inspection scenarios and application requirements. Below are several major classifications of industrial inspection lenses:

Fixed Focus Industrial Lenses：

Characteristics: constant focal length, the range of vision changes with the working distance.

Application Scene: suitable for detecting the working distance is fixed, and the detection area is the same plane of the scene.

Zoom Industrial Lens：

Characteristics: Focal length can be realized to change, so as to obtain different width and narrow angle of view.

Application Scenario: Suitable for inspection scenarios that require flexibility but not high resolution.

Zoom Industrial Lens：

Features: Magnification can be continuously and infinitely adjusted within a certain range, providing high contrast and high resolution imaging.

Application Scenario: Suitable for semiconductor inspection, scientific research and other high-precision imaging requirements.

Telecentric Industrial Lens：

Features: constant magnification, not affected by changes in working distance, can eliminate parallax of traditional industrial lenses.

Application Scenario: Suitable for detecting the situation where the measured objects are not on the same object surface, such as food boxes, beverage bottles and so on.

Macro Industrial Lens：

Characteristics: With a large magnification ratio, it is suitable for photographing smaller objects.

Application Scenario: Used in scenarios that require high magnification for fine inspection.

Line array industrial lenses：

Characteristics: used with line array camera, scanning mode of operation, requiring the lens to move relative to the target.

Application Scenario: Used in occasions that require high-speed, high-resolution image acquisition and processing.

Microscope head：

Features: short working distance, high magnification, small field of view.

Application Scenario: Used for high resolution occasions, such as scientific research, biological detection, etc.
