Security Division Backlog at New Record $124 million as of March 31, 2007OSI Systems, Inc. (NASDAQ: OSIS), a vertically-integrated provider of specialized electronic products for critical applications in the Security and Healthcare industries, announced today that its Security division, Rapiscan Systems, has received an order from an undisclosed international customer for 17 Cargo & Vehicle Inspection systems. The order was reflected in the Security Divisions record backlog of approximately $124 million as of March 31, 2007 compared to $115 million as of December 31, 2006. Due to competitive purposes, the value of the contract was not disclosed. 

Rapiscan Systems provides a broad range of scanning technologies allowing its customers either stand-alone systems or customized hybrid solutions to optimize scanning performance. Systems to be delivered under this order will come in varying configurations utilizing X-ray,and Neutron technologies.

Rapiscan Systems President, Ajay Mehra, said, This announcement marks a significant milestone for us.  As our single largest international order, it speaks volumes to our continued international growth and to the ever-expanding relationships with our customers.  Further, it underscores our commitment to mitigating global security threats, as evidenced by the breadth of our products and services offerings.

Rapiscan Systems high-energy X-ray product line, marketed under the Eagle brand name, is a high-performance 4.5 MV x-ray inspection system, providing approximately 280mm -300mm of steel penetration to rapidly and accurately inspect containers and trucks at seaports and land border crossings.  The Eagle's high-energy x-ray imaging system can produce a high-resolution image of a 20-foot container in less than 10 seconds. Even dense cargo can be clearly imaged reducing the need for time consuming manual inspections.

Rapiscan Systems proprietary material-specific Thermal Neutron Analysis ("TNA") technology automatically produces a "red light/green light" response for the operator indicating whether or not the suspicious object is a threat. This process minimizes human error in image interpretation and the associated cost incurred from having to manually inspect the contents of the container.
