Filed: 1993-05-31
Abstract: PURPOSE:To prevent ghost by depositing light absorbers by evaporation on both surfaces of one optical member selected from plural optical members constituting the optical system of a camera, thereby constituting the ND filter. CONSTITUTION:The reflected light A reflected by an image forming face 7 is absorbed by a light absorber 5B disposed on the exit face side 3B of a lens group 3 and the reflected light reflected by the light absorber 5A without being absorbed is absorbed by the light absorber 5B when the ND filter 10 is constituted by depositing the light absorbers 5A, 5B by evaporation on the incident side face 3A and exit side face 3B of the lens group 3. The light past the light absorber 5B is an extremely slight in light quantity and does not, therefore, cause problems, such as ghost. The reflected light B reflected forward by the light absorber 5B is absorbed by the light absorber 5A and the reflected light reflected by the inside wall of a lens barrel 8 without being absorbed is absorbed by the light absorber 5A. The reflected light past the light absorber 5A is absorbed by the light absorber 5B. The light past the light absorber 5B is extremely slight in light quantity and does not, therefore, cause problems, such as ghost.

Abstract: PURPOSE:To convert the light of a light source having randomly polarized light to one kind of polarized light with high efficiency by disposing a phase difference plate between a reflection type linear polarizing optical element which allows the transmission of one polarized light and reflects the other polarized light and a mirror. CONSTITUTION:The phase difference plate 3 is disposed between the reflection type linear polarizing element 4 provided in front of the light source and the mirror 2. The one polarized light 10 passes the reflection type linear polarizing element 4 and the other polarized light 11 is reflected by the reflection type linear polarizing element 4 and passes the phase difference plate 3 to become ellipticaly polarized light 13. This polarized light 13 is reflected by the mirror 2 to become the counter-elliptically polarized light 14 which passes the phase difference plate 3 again to form the polarized light 15 having the same component as the component of the polarized light 10. This light passes the reflection type linear polarizing element 4 with the high efficiency. The phase difference plate 3 is the phase difference plate which generates a phase difference of nearly a quarter wavelength with respect to visible light. The efficiency of the linear polarized light source is maximized when the optical axis thereof is installed at nearly 45 deg. angle with the axis of the polarization of the reflection type linear polarizing element 4. The light of the randomly polarized light source is converted to one kind of the polarized light with the high efficiency in this way.
