Digital Precision Corp is a global provider of video microscopes, manual measuring systems, and multisensor digital video coordinate measuring machines, bringing the latest technologies and new approaches to a wide variety of industry inspection tasks to significantly improve image quality and reduce processing time. Located in Huntington Beach, CA, the company builds shop-ready measurement solutions to meet customers'' exacting specifications in semiconductor manufacturing, machine shops, and other quality-control applications.
When challenged recently with issues of both performance and price in the design of two newly ordered video metrology and gagging measurement machines, Digital Precision turned to Toshiba Teli America, Inc for cameras that would accurately capture video images of various size workpieces. These images in turn would be transferred to a video monitor for on-screen analysis using Digital Precision''s proprietary software.
Company representatives consulted with Al Sabeh, vp of sales, Toshiba Teli America, Inc.
"After reviewing the two designs, I recommended incorporating our new CSB4000F 4-megapixel CMOS camera with FireWire and 2008 x 2047 resolution [shown below]," says Sabeh. "On the other machine, I recommended our CS6910F [shown above], a next generation FireWire® color camera that leverages a honeycomb-style Super CCD® to achieve SXGA resolution images at up to 30 frames per second."
The CSB4000F''s ultra-high resolution qualified it for use with large FOV (field of view) measurement and inspection. Coupled with an FOV microscope, the camera can measure larger size parts, such as 50 x 50 mm, with better than 5 µm accuracy online or off-line without an expensive stage. When using stage, the system can measure one part in an FOV or an array of parts, thus increasing the performance dramatically.
Yan Yu of Digital Precision Corp gave the CSB4000F high marks: "The camera has a reduced overall cost and the measurement and inspection is extremely accurate."
The CS6910F was employed in a stage driven system, explained Yan.
"We found the CS6910F to be an excellent replacement for traditional CCD cameras. It offers simple installation, improved resolution with excellent color reproduction, and overall excellent accuracy."
