  • Patent number: 11761901
    Abstract: Examples disclosed herein relate to a method and apparatus for inspecting lamp dimensions. The method includes determining an actual measurement of a lamp. The lamp is configured to heat a substrate in a substrate processing apparatus. A window is generated, the window having a width and a height. The window is based upon a target measurement of the lamp. The method further includes generating a deviation based upon a difference between an image of the actual measurement and the window. The deviation is compared to a first threshold. The lamp is rejected if the deviation is outside the first threshold.
