Telecentric lens industry application

One of the most important advantages of a telecentric lens is that changes in object distance do not affect the magnification of the image. Due to the unique technical advantages of telecentric lenses, the current requirements for high-precision inspections such as mechanical part measurement, plastic part measurement, glass product and medical part measurement, and electronic component measurement are particularly suitable for precision measurement occasions.

When would you use a bi-telecentric lens:

1. When the thickness of the detected object is large and more than one plane needs to be detected, typical applications are food boxes, beverage bottles, etc

2. When the placement of the measured object is uncertain, it may be at an angle to the lens;

3. When the measured object bounces up and down during the detection process, such as when the working distance changes due to vibration on the production line;

4. When the measured object has an aperture or a three-dimensional object;

5. When a low distortion rate is required and the brightness of the image effect is almost identical;

6. When the defects to be detected can only be detected under parallel illumination in the same direction;

7. When it is necessary to exceed the detection accuracy, such as when the allowable error is 1um.

Telecentric lens specific application scenarios

1. Precision parts measurement

The most common application of telecentric lenses is to measure the dimensions of precision mechanical parts. Telecentric lenses are mainly used for measuring precision mechanical parts such as springs, screws, nuts and washers.

2.Measurement of plastic parts

Another major application of telecentric lenses is measuring rubber seals, O-rings, and plastic caps. Objects are characterized by easy deformation during movement and measurement, and traditional measurement methods are more difficult. The detection methods of these parts require non-contact optical measurement technology.

 3. Measurement of electronic components

Many other components (such as resistors, transistors, and integrated circuits) require small telecentric lenses to check their integrity, size, specifications, position, and camber of the pins, and the electronic drawing board needs to detect the spacing of each component. Other electronic products such as transistors and IC circuits require the use of telecentric lenses to detect their size and location of connection points, and circuit boards are often used to control the distance between electronic components.

4. Measurement of glass products and medical parts

Many pharmaceutical glassware such as vials, capsules, and vials are generally measured with a telecentric lens to ensure complete sealing and prevent damage to the vessel. There are similar applications in the beverage industry, such as measuring the thread of a glass bottleneck. Other medical passive devices such as syringes also require telecentric inspection system technology.

5. Other special uses

Telecentric lenses have other applications, such as:

Particle measurement

2. High-precision color measurement in the printing industry;

3. Photomask measurement;

4. Filter control;

5. Blood analysis and cytometry.
