What is an optical sorter?

Optical sorter is a device that automatically sorts objects based on visual criteria. Optical sorters also often occur in production and food equipment, also known to sorting machines. They are used to find defects and separation of different types of items. There are several different types of sorters, including some that use light sensors, while others use infrared light.

One of the primary uses of an optical sorter is to find defects in the products and remove unsatisfactory items from the production process. These deficiencies can only be superficial or may indicate that the product is defective or dangerous. In a factory that creates a specific size item, such as variations of defect or size with one of the products can cause significant problems. The optical sorter can detect the defect and remove the incorrectly size before loosening from the factory. They are also used to maintain different types of items. This ability is particularly important for the application processingVin. In devices where consumer products are packed, optical sorters are able to identify and prevent foreign objects to be randomly processed. This helps maintain packed food clean and prevents the introduction of dangerous and inedible objects in food supply.

There are several different types of optical sorters. The most basic design uses a simple light sensor called a photodetector. They are able to feel the amount of light reflected by an object. Because dark objects absorb light, the optical sorter with a photodetector can categorize items based on color contrast.

Optical sorters are not limited to the abilities of the human eye. Some sorting machines use infrared sensors for sorting objects with optical differences That are imperceptible to human workers. These machines project infrared light on objects and detect the level of reflection of thisof the light light. Other optical sorting machines combine laser beams with high sensitivity detectors to detect very small variations or cracks in the product too small to see the human eye.

In addition to categorizing items based on color absorption and light, some optical sorters are also able to communicate the shape of the object. These advanced versions use digital cameras to capture high -resolution optical data that are loaded into the computer. Using image processing software, the computer can identify the lines in the image and determine its general shape. This advanced type of optical technology is very useful for sorting items that are made of the same material but have different outlines.
