TC Series Bifocal Telecentric Lenses

The TC Series Bifocal Telecentric Lenses are critical components for various precision measurement systems based on machine vision technology. When paired with high-resolution, small-pixel sensors like the 5.5 million-pixel 2/3" sensor, these lenses utilize bifocal technology to truly harness the advantages of telecentricity, resulting in nearly distortion-free imaging.

 

Customers can easily select the matching lens by the product model, where the "xx" indicates the sensor size (13 = 1/3"; 12 = 1/2"; 23 = 2/3"), and "yy" represents the horizontal Field of View (FOV) size in millimeters.

 

For example, TC 12 64 means it is compatible with a 1/2" sensor and offers an observable FOV of 64 (x48) millimeters."

 

This translation captures the essence of the original text, explaining the purpose and features of the TC Series Bifocal Telecentric Lenses, as well as how to select the appropriate lens based on sensor size and FOV requirements.

Here's the translation of the numerical annotations in the specification parameter list:

1. Working Distance: Refers to the distance between the front lens and the object. To achieve the best resolution and minimize distortion, set the distance to the indicated value with an allowable deviation of +/- 3%.

2. Working F-number: The actual F-number when using a macro lens. Smaller aperture lenses can also be provided according to requirements.

3. Although images can still be used for measurement at the edges of the depth of field, only half of the depth of field marked value should be referenced for obtaining sharper images.

4. Maximum slope of the lens normal: When converted into milliradians, it provides the maximum measurement error in millimeters for object displacement.

5. Measured from the mechanical front end to the lens edge.

These translations clarify the meaning and usage of the numerical annotations in the specification parameters.
