Application scenarios of telecentric lenses

With the widespread use of machine vision systems in precision inspection fields, standard industrial lenses may not meet the stringent requirements of precision inspections. To address this gap and meet the demands of high-precision detection, telecentric lenses have emerged as a suitable solution.

Here are the standout features of telecentric lenses:

1. High Resolution: Telecentric lenses provide high resolution for detailed inspection.
2. Ultra-Wide Depth of Field: These lenses offer a wide depth of field, allowing for a clear focus across varying distances.
3. Ultra-Low Distortion: Telecentric lenses exhibit minimal image distortion, which is crucial for precise measurements.
4. Unique Parallel Light Design: The optical design ensures consistent light rays, resulting in uniform imaging.

Applications of Telecentric Lenses

One of the key advantages of telecentric lenses is that changes in object distance do not affect the magnification of the image. Due to their unique technical benefits, telecentric lenses are especially useful in applications requiring high-precision measurements, including:

• Mechanical part measurements
• Plastic part measurements
• Glass product and pharmaceutical component measurements
• Electronic component measurements

Scenarios Requiring Dual-Side Telecentric Lenses

Dual-side telecentric lenses are suitable for various specific applications, including:

1. Large Object Thickness: When the object being inspected has significant thickness, requiring inspection of multiple planes (e.g., food containers, beverage bottles).
2. Variable Object Position: When the object's position may vary, causing it to be at an angle relative to the lens.
3. Vertical Movement: When objects vibrate or bounce during inspection, causing variations in working distance.
4. Objects with Apertures or 3D Shapes: For inspecting complex objects that have holes or are three-dimensional.
5. Low Distortion and Consistent Brightness: When a low distortion rate and nearly uniform image brightness are required.
6. Specific Lighting Requirements: When defects can only be detected under parallel lighting from the same direction.
7. High Precision Tolerance: When precise measurement with a tolerance of 1 micron is required.

These scenarios highlight the importance of telecentric lenses in precision inspection, offering unique features and technical advantages for a variety of applications.
