Product Overview
The Imaging Specialist
What is a Camera?
Camera is use to capture an image. It is similar to the retina system in our human eye. Images fall on the sensor of the camera and are read out and transfer to the PCs for image processing. Basically, all the cameras use in the machine vision application is digital camera. Camera can be classified under 2 categories – Area scan and Line scan. Under each classification, there are different types of cameras in features and technical specification and are use for different application requirement in the industry.
Calibration Targets
What is a Calibration Targets?
As the name imply, calibration target is use to calibrate the vision system in the trial run to produce a quality image that are needed or measurement, etc. Calibration target is application specific. Therefore, calibration target can be design similar to the product that the machine is meant to inspect.
Frame Grabbers
What is a frame grabbers?
A frame grabber is the interfacing card between the camera and the PC. It is one of the key elements in an image processing system. It is use to acquire video information and to transfer that information to the succeeding stages of the system. Frame grabbers convert video images from cameras into digital format and transfer these digital images to PCs, which use the converted data to make decisions about the object(s) being inspected. Though performing these functions quickly and reliably are critically important to the success of a machine vision inspection, frame grabber is much more than mere data converters and transfer conduits. Frame grabber offers a range of capabilities that can compensate for poor lighting, optics and ways that camera sensors present information to the frame grabber, increasing the quality of the images acquired and, ultimately, helping the machine vision system perform more reliable inspections.
What is Lens?
Lens is basically used to focus an image onto the sensor in a camera. All cameras have fixed sensor size. This means that no matter how large the image is at the sensor plane, the camera will only “look at” the portion of the subject equal to the sensor size. What the camera “sees” is called the field of view. The lens, or lens system, of the camera controls the magnification at the camera sensor. There are many types of lenses. Some of the common categories of lenses are: CCTV, FA, Large format, Telecentric and Microscopic. These lenses have different functions and are therefore application specific.
Lighting & Laser
The rays which are reflected from the illuminated subject can be measured with suitable imaging equipment. The quality of these reflected rays is of paramount importance from the success of post-acquisition image processing. To obtain good results with post-acquisition image processing, there has to be intimate interaction between optics, mechanics and electronics, which can only be realized with high quality lighting components. Lighting is the key to success in image processing - without the proper lighting, you can forget getting results!​
Why Software?
Software is the “education” of the computer. Without software, the computer does not have the understanding to do anything. There are many type of education - what to acquire for personal development? Similarly, there is a lot of different type of software for imaging application. The software not only must help to solve the image-processing requirement, but also reduce engineering man-hour. Therefore, choosing the correct software for your application is very important.
Stands are to mount your equipment and provide a stable platform during the process of imaging. A stable stands provide you non-shaking or fuzzy image. Below are stands meant for your laboratory or evaluation testing purpose.
Homeland Security
To improve our country security and prevent human injury, unmanned equipment is an area that most developers of security equipment are headed. Computerized pan-tilt, remote electronic eyes, ruggedize cameras are components that you may want to consider in building your secret equipment.
Interfacing Adaptors
What is an Interfacing Adaptors?
There was Analog video interfacing camera such as PAL, NTSC, Secam, CCIR, EIA, etc. Then come digital video interfacing camera such as LVDS, RS422, USB, Firewire, Cameralink, etc. More and more new Video Interfacing protocol is being developed as market advance. To ensure that previous protocol camera can use in new interfacing display equipment, manufacturers develop Interfacing Adaptors Module to convert LVDS to Cameralink or Analog to USB, etc.
Legacy Components
Legacy Components
Component product life-span is short nowadays. However, the automation machine is high investment. When a vision system is faulty due to one of the components. It is cheaper to replace the faulty component versus upgrade the machine vision system because of obsolete vision components. VPT has some legacy product below that may solve your problem. If you are unable to find your legacy component below, don’t worry. We are plug into the vision components stockist network and may help you find your obsoleted components. Send us an email with the brand and model and we will help you to search.
Failure Analysis Equipment
Failure Analysis Equipment
Semiconductor Failure analysis (FA) is the process of determining how or why a semiconductor device has failed. It is often perform as a series of steps known as FA techniques. Device failure is defined as any non-conformance of the device to its electrical and/or visual/mechanical specifications. Failure analysis is necessary in order to understand what caused the failure and how it can be prevented in the future. Some of the FA equipment use in Failure analysis is: - Scanning Electron Microscope (SEM) - Acid Decapsulator - Mechanical Decapsulator - Laser Decapsulator - Silicon Backside Preparation System - X-Ray Inspection System
