  • Microscope Optical Components - Introduction

    A straight line connecting the centers of Lens(a) and Lens(b) is referred to as the optical axis of the lens system. In the dual-lens system (Figure 4), a spherical wavefront emanating from light source point S(1), and located at a distance δ from the optical axis of the lens, is converted by Lens(a) into a plane wave.

    2013-10-21u2002·u2002Off-axis parabolic mirrors (OAPs) 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. However, when used improperly, OAPs can be difficult to align and achieve ideal imaging.
