Abstract:
A system and method for inspection is disclosed. The design includes an objective employed for use with light energy having a wavelength in various ranges, including approximately 266 to 1000 nm, 157 nm through infrared, and other ranges. The objective includes a focusing lens group having at least one focusing lens configured to receive light, a field lens oriented to receive focused light energy from said focusing lens group and provide intermediate light energy, and a Mangin mirror arrangement positioned to receive the intermediate light energy from the field lens and form controlled light energy. Each focusing lens has a reduced diameter, such as a diameter of less than approximately 100 mm, and a maximum corrected field size of approximately 0.15 mm. An immersion substance, such as oil, water, or silicone gel, may be employed prior to passing controlled light energy to the specimen inspected.
