AN OPTICAL ELEMENT HAVING TWO PHASE MASKS |
摘要 |
An optical element is disclosed. The optical element comprises: a first phase shift mask formed on a first optical material and constituted to generate a positive phase shift, and a second phase shift mask formed on a second optical material and constituted to generate a negative phase shift, wherein the phase shift masks are arranged serially on an optical axis, and wherein a refractive index of at least one of the first and second optical materials varies with the temperature at a rate of at least 50x10-6 per degree Kelvin. |
