CHIOPT Non-standard Telecentric Lenses

With the specific application scenarios, special detection requirements, and changes in non-standard installation environments in the detection industry, higher requirements have been put forward for lenses. 

In this context, CHIOPT has upgraded the standard telecentric lens to a non-standard telecentric lens to meet the industrial inspection and imaging needs in special applications.

'Non standard' refers to non-standard, and non-standard telecentric lenses are relative to standard telecentric lenses. Standard telecentric lenses typically have fixed magnification, interfaces, and other specifications that can meet general industrial inspection or imaging needs. 

Non standard telecentric lenses are customized designs and manufactured based on specific application scenarios, special testing requirements, or non-standard installation environments.

Special size inspection

When the size of the object to be detected is too large or too small, beyond the field of view of the standard telecentric lens, it is necessary to customize a non-standard telecentric lens.

For example, when detecting tiny electronic chip components, their size may only be a few millimeters or even smaller, and standard lenses may not provide sufficient magnification to clearly observe the details of the components. In this case, it is necessary to design non-standard telephoto lenses with shorter focal lengths and higher magnification.

Installation space restrictions

In some automated production lines or equipment, the installation space for lenses is very limited. For example, in small precision instruments and equipment, a telecentric lens needs to be installed in a narrow space for detection. At this point, it is necessary to design non-standard telephoto lenses with smaller external dimensions and compact structures to adapt to special installation environments.

Working distance requirements

The working distance refers to the distance between the front end of the lens and the object being detected. If testing is required at a specific non-standard working distance, such as a very short (within a few centimeters) or very long (several meters) working distance, it is necessary to customize a non-standard telecentric lens that meets this working distance requirement.

For example, in some large-scale industrial warehousing scenarios, it is necessary to detect the label and other information of goods at a long distance, which requires a non-standard telecentric lens with a long working distance.

Special design process requirements

If the detection task involves special color correction, such as RGB confocal, standard telecentric lenses may not be able to meet the requirements.

High resolution and contrast requirements

For some applications that require extremely high imaging quality, such as high-precision medical image detection or defect detection of aerospace components, non-standard telecentric lenses need to have higher resolution and contrast. This may involve the use of special optical materials, more complex optical lens combinations, and more precise optical designs to meet these requirements.

Difference from standard telecentricity

Standard telecentric lenses generally have strict optical design specifications, such as dual telecentric lenses, whose entrance and exit pupils are located at infinity, ensuring that the magnification of objects remains almost unchanged within a certain range of object distance.

However, the optical structure of non-standard telecentric lenses may be altered due to special requirements. For example, in order to accommodate special installation spaces or achieve specific imaging angles, the number of lenses, lens shape, and barrel shape may differ from standard telecentric lenses.

CHIOPT currently has non-standard telecentric lenses with a target surface coverage of 1/1.8- φ 44, with a magnification range of 0.1X-3X to choose from, and provides customized services. Our annual customized business exceeds 50 pieces.
