1. An apparatus for toasting a food product, comprising:

  • a toasting chamber adapted for receiving a food product to be toasted, the toasting chamber having first and second sides;

    a first infrared heater comprising a first electrically conductive filament inside of a first quartz glass tube, the first infrared heater being located on the first side of the toasting chamber;

    a second infrared heater comprising a second electrically conductive filament inside of a second quartz glass tube, the second infrared heater being located on the second side of the toasting chamber;

    a first radiant heat reflector located on the first side of the toasting chamber, wherein the first infrared heater is located between the toasting chamber and the first radiant heat reflector; and

    a second radiant heat reflector located on the second side of the toasting chamber, wherein the second infrared heater is located between the toasting chamber and the second radiant heat reflector;

    wherein the first and second quartz glass tubes are chemically etched so as to pass a desired infrared wavelength from the electrically conductive filament, andwherein the first and second infrared heaters emit infrared radiant heat at a wavelength optimized for toasting of the food product.
