It is conceivable to form a boundary lens using the developed fluorite. However, it has been found that fluoride has the property of dissolving in water.For example, if fluorite is used to form a boundary lens and pure water is used as the immersion liquid, the optical surface of the boundary lens becomes pure water (immersion). In other words, the projection optical system cannot easily maintain the imaging performance over a long period of time due to the influence of the liquid.

Precision processing cannot be performed. It is more preferable to set the upper limit value of the conditional expression (1) to 0.7, because even if the irradiation energy is increased, the effect of compaction can be suppressed and high throughput and high resolution can be realized.

Therefore, the image forming optical system (projection optical system) does not damage the optical surface of the second optical member under the influence of pure water and, consequently, does not damage the optical surface of the boundary lens under the influence of pure water. Good image performance can be maintained over a long period of time.
