Why use a bi-telecentric lens to effectively reduce inspection stations?

As a branch of industrial lenses, dual telecentric lenses are increasingly being used in various machine vision projects, offering unique advantages that can solve complex and difficult project issues. However, because they are not as widely adopted as conventional industrial lenses, many engineers do not fully utilize dual telecentric lenses in their solutions, resulting in inefficient and costly project designs. Here are some practical application scenarios to discuss and analyze why and in what circumstances dual telecentric lenses should be used.

Dual Telecentric Lenses

Using dual telecentric lenses can help avoid setting up multiple workstations, simplify the coordination between them, save hardware costs, and reduce unnecessary software development. In vision inspection projects, multiple workstations are often needed to meet complex inspection requirements or to accommodate irregularly shaped workpieces. This is especially true for workpieces with significant height variations, curved surfaces, threads, flanges, multi-thickness holes, inner slots, and outer diameter steps.

These types of workpieces often require multiple setups because conventional lenses struggle with small depth of field and strong reflections from metal surfaces. As a result, they cannot effectively inspect multiple features simultaneously.

Dual telecentric lenses can address these issues by offering consistent magnification and a large depth of field, allowing for the simultaneous inspection of complex workpieces in a single setup. This approach reduces the need for multiple workstations, optimizes software, enhances inspection efficiency, and reduces costs.

As more projects adopt dual telecentric lens technology, they achieve improved efficiency and cost-effectiveness. By continuously promoting this technology, the goal is to bring greater value to a wider range of applications.
