Problems solved by bitelecentric lenses

Problems Addressed by Double Telecentric Lenses

1. Resolution Problem: Traditional industrial lenses have limited resolution, typically around 10 micrometers, which aligns with 10-megapixel cameras. However, with the advancement of high-resolution cameras and high-precision measurement needs, regular lenses can't keep up. Double telecentric lenses can handle this increased demand for resolution, aligning with high-resolution cameras and high-precision measurements.

2. Depth of Field Problem: Regular lenses have a limited depth of field, which means if the object being measured extends beyond this range, accurate detection and measurement may not be possible. Double telecentric lenses offer a broader depth of field, allowing them to focus on objects with varying depth, crucial for high-precision tasks.

3. Magnification Variation Problem: The magnification of regular lenses varies with changes in working distance, causing unacceptable errors when used for precision measurement tasks. Double telecentric lenses provide consistent magnification regardless of the object distance, ensuring high accuracy.

Features of Double Telecentric Lenses

1. Large Size and Field of View: Double telecentric lenses have a parallel light entry and exit, meaning that the lens's barrel size must match the area of the parallel light required. This characteristic often results in larger-sized lenses. The larger the field of view, the bigger the lens size.

2. Field of View and Compatibility: Double telecentric lenses offer a broader field of view, and they are compatible with larger CCD sensors. Their interface type and working distance can vary, as long as it doesn't hinder usability.

3. Reduced Reflected Light and Noise: Double telecentric lenses only accept parallel light, filtering out almost all diffuse reflected light. This results in a darker image in natural environments but provides clearer and more stable edge detection, removing noise from the measurement process. Using parallel light sources can further enhance the performance of double telecentric lenses.
