A method and system for measuring stray light for use in an exposure apparatus uses an image sensor to be disposed at a wafer level in the exposure apparatus. The stray light is measured by preparing a reference pattern and a measuring pattern on a reticle. The reference pattern includes a light shielding region having first open regions for transmitting light to a center of an active region of the image sensor. The measuring pattern includes a light shielding region having second open regions for transmitting light to a periphery of the active region. A first intensity of light reaching the active region after being filtered by the reference pattern and a second intensity of light reaching the image sensor after being filtered by the measuring pattern are measured. The intensity of the stray light is evaluated by a difference between the first and second light intensities.

First integrating circuits 110 convert electric currents from one group of photosensitive portions electrically connected to each other in a plurality of pixels arranged in a first direction into voltages, and output the voltages. First S/H circuits 130 hold and output the voltages outputted from the first integrating circuits 110. A first maximum value detecting circuit 140 detects the maximum value of the voltages outputted from the first S/H circuits 130. First level shift circuits 170 shift levels of the voltages outputted from the first S/H circuits 130. A first A/D converter circuit 180 sets a range from the maximum value detected by the first maximum value detecting circuit 140 to a value smaller than the maximum value by a predetermined value as an A/D conversion range, and converts the voltages outputted from the first S/H circuits 130 into digital values within the A/D conversion range.

The present lighter includes two basic components, a housing and a fuel cartridge. The housing may comprise multiple pieces. The fuel cartridge is easy to remove from the housing without the use of any tools. Thus, an empty fuel cartridge can quickly be replaced with a full one by the user. Replacing the fuel cartridge, rather than refilling it, prevents the user from coming into contact with lighter fuel. The housing and the fuel cartridge are each relatively inexpensive to mass produce. Thus, a worn or damaged housing may be removed from the lighter by the user and replaced with a new housing. The disposability and replaceability of the lighter components makes repairs to the lighter quick and inexpensive. All or part of the housing may also be replaced with a housing having a different outward appearance. A user can thus change the appearance of his or her lighter by changing housings, rather than having to purchase multiple lighters. The housing may include surface features, such as bosses, ribs and/or tensioning springs, to tighten a fit of the housing and prevent spontaneous separation. The surface features may also protect the appearance of the housing.
