OPTICAL COMPONENTS AND INSTRUMENTS		PARABOLOID FOCUS Off-Axis Paraboloids Enhance Laser Power Density Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP’s offer the ability to focus collimated light without introducing spherical aberration. Continue…
