Service Physics, Inc. (SPI) was started in 1991 to provide maintenance and aftermarket products for the Surface Science Instruments line of ESCA/XPS instrumentation. The principals of SPI were involved in the R&D, customer service and management at Surface Science Instruments prior to its sale in 1987. We provide upgrades that keep the instrument’s technology current. The system serviceability is improved by updating obsolete components and new features are available as upgrades. Service Physics(SPI) has a unique perspective about instrument design. After servicing the original instruments over the last 30 years we understand what improvements were left to be accomplished and also why they have endured so long as solid instruments. The best features have been strengthened and the weak components have been replaced. Customers demand improved safety of operation and ease of use while maintaining reliability and ease of repair. The instruments have become robust, reliable work horses that provide even the novice with top quality information. Last year we introduced the exciting new Super Hawk XPS. The data rate is increased by more than 2.5 times. HD viewing and precision auto alignment are included. Please visit our site often to learn about the new products that will soon be announced.
