Agilent Technologies Inc. today announced that its laser navigation sensor technology is now available to mouse manufacturers worldwide. Three versions of the industry's first laser-based optical mouse sensors are being offered: one for high-end cordless mice, one for high-end corded mice, and a version optimized specifically for the high-performance gaming environment.
Laser illumination is superior to LED-based illumination in that it reveals trackable surface structures the LED light source cannot uncover. Laser mice using this technology can easily track on painted metal, polished wood-grain surfaces, glossy photo paper, translucent plastic, frosted glass and many other previously difficult surfaces.
"In 1999 we revolutionized the computing world with the first LED-based optical mouse sensor, and we've done it again with our patented LaserStream technology," said Ngoh Kee Hane, vice president and general manager of the Navigation Products Division in Agilent's Semiconductor Products Group. "LaserStream uncovers microscopic detail, which enables mice to track with incredible accuracy on more surfaces and with greater responsiveness than ever before. Due to lasers' superior tracking ability and reduced power consumption, we expect this revolutionary LaserStream technology to ultimately replace the LED-based optical mouse sensor in virtually every application."
Laser mice built around Agilent's LaserStream technology provide positioning accuracy with resolutions up to 2,000 counts per inch (cpi), and can keep up with rapid movements with maximum velocities up to 45 inches per second (ips) and acceleration of up to 20g. This higher performance is required for gaming and demanding graphics applications (average users, in contrast, move their mice no faster than 14 ips and 2g). Other features include adjustable frame rates (the number of "snapshots" the sensor takes per second) in excess of 7,000 fps.
Agilent offers its LaserStream technology as separate components or in bundles that include the sensor, VCSEL (vertical-cavity surface emitting laser), round or rectangular lens, and a VCSEL assembly clip. The Agilent LaserStream product line offers three versions of laser navigation sensors and mouse bundles:
- ADNS-6000 laser navigation sensor/ADNB-600X bundle for high-end corded mice. The ADNS-6000 features 800 cpi resolution, 20 ips maximum velocity and 6,400 fps frame rate.
- ADNS-6030 laser navigation sensor/ADNB-603X bundle for high-end cordless mice. The ADNS-6030 features up to 800 cpi resolution, 20 ips maximum velocity, and enhanced self-adjusting frame rate, along with low power consumption for battery life of up to six months.
- ADNS-6010 laser navigation sensor/ADNB-601X bundle optimized for the gaming environment and other specialized high-performance applications. The ADNS-6010 features 2,000 cpi resolution, 45 ips maximum velocity and 7,080 fps frame rate.
A key component of the Agilent LaserStream technology is the company's ADNV-6330 842 nm wavelength VCSEL. This VCSEL was engineered to provide a laser diode with a single longitudinal and a single transverse mode, which, in contrast to most oxide-based single-mode VCSELs, remains in single-mode operation over a wide range of output power. The low operating current of the ADNV-6330 allows lower power consumption in optical mice.
Agilent's laser mouse sensor has been designed and tested on a variety of fault conditions, which enable mouse manufacturers to meet IEC-60825-1 eye safety class 1 requirements as defined by the International Electrotechnical Commission (IEC).
The ADNS-6030-based bundle (ADNB-603X) is priced at less than $5 in high volumes, the ADNB-600X bundle at less than $6, and the ADNB-601X bundle at less than $7. The sensors, bundles and individual ADNV-6330 VCSELs, optics and clips are available now through Agilent's direct sales channel and worldwide distribution partners.
