Title: Polarized light illuminating apparatus
Inventor: GOTO MANABU
IPC: G02F1/1337
Filed: 2001-06-05
Abstract: PURPOSE: To prevent the extinction ratio of polarized light irradiating a work from lowering even when the polarization direction of the incident polarized light on a reflection mirror is varied. CONSTITUTION: Light from a lamp 1 is made incident on a polarizing element 8. Polarized light emitted by the polarizing element 8 is reflected by a second plane mirror 6 and irradiates an alignment layer of the work W via a mask M. A protective film 11 is formed on a surface of the second plane mirror 6. The kind of the protective film 11 and the optical thickness of the film is selected so as to make difference in a phase shift Δ between P polarized light component and S polarized light component emitted from the second plane mirror 16 satisfy an inequality Δ <= ±20° corresponding to an incident angle and a wavelength of the polarized light. Consequently, the extinction ratio of the polarized light irradiating the work W is not lowered even when the polarization direction of the incident polarized light on the second plane mirror 6 is varied. Also, optionally the incident angle of the polarized light on the plane mirror is reduced by using a plurality of plane mirrors instead of the second plane mirror 6 or the difference in the phase shift Δ may be canceled by two sheets of plane mirrors.
