Claim:
1. A method for measuring the temperature of cookware to be induction-heated, comprising the steps of: providing an infrared temperature sensor and an induction heater having a countertop for supporting the cookware, the countertop comprising a first material and having a viewing window comprising a second material located between the infrared temperature sensor and the cookware, wherein the second material of the viewing window comprises plastic or silicon or germanium, and wherein the viewing window prevents fluids or other physical contaminants from contacting the induction heater while providing visibility to infrared waves; providing a controller, an electronic storage medium, and an induction heating coil in responsive communication with the controller; sensing a temperature of the cookware using the infrared temperature sensor; covering at least a portion of the infrared temperature sensor with a metal tube to narrow the field of view of the sensor, and using the controller to automatically apply at least a first algorithm utilizing a measured temperature of the metal tube, wherein the at least first algorithm is stored in the electronic storage medium and is used to adjust the sensed temperature of the infrared temperature sensor to compensate for the narrowed field of view of the infrared temperature sensor, thereby providing a temperature of a portion of the heated cookware within the narrowed field of view, wherein the first algorithm comprises the following T
