  • Specifying the Geometry of Off-Axis Parabolic Mirrors

    The growing need for advanced reflective optics operating over a broad bandwidth has motivated the development of off-axis parabolas with higher imaging performance then ever before. Specifying imaging and wavefront performance over a broad range of spatial frequencies is essential for enabling the highest levels of performance. As system level requirements have advanced, the way we specify OAPs must also change. Within recent years everything about OAP’s has evolved including tolerances for quality and performance, manufacturing methods, testing methods, thin film coatings and alignment technologies. AOS continues to re-engineer the Off-Axis Parabola to meet the needs of tomorrow’s applications. These topics are explored in a series of new application notes from Aperture Optical Sciences Inc. This paper provides instruction on how to define the key geometric features of Off-Axis Parabolic Mirrors (OAPs) and describes the concept of axial offsets as a function of off-axis angle.

  • Controlling k, f(s ),θ, and OAD Tolerances on Off-Axis Parabolas

    Controlling quality of off-axis parabolic mirrors requires tolerances that are both traceable to performance and verifiable by measurement. Primary aspheric parameters for off-axis parabolic (OAP) mirrors, include the conic constant (k), focal length (f), off-axis angle (OAA or “θ”) and off-axis distance (OAD). However, because the primary design parameters in an asphere are interdependent, it is not always practical or even possible to verify these quantities by independent measurement as you may for a sphere or flat optic. Therefore, if something so fundamental as focal length or off-axis angle cannot easily be verified, how can the quality be guaranteed? This application note explains how AOS addresses this fundamental question. Our answer may surprise you.

  • Zero-Expansion Ceramic Mirrors

    Ceramic Materials enable mirrors with greater durability and resistance to mechanical and thermal loading than glass. This application notes provides you with all you need to know about Cordierite materials for optics.

  • Advantages of the parallel configuration OAP

    The typical image that comes to mind when thinking about off-axis parabolas is the wedged-configuration mirror section cut out of a larger parent parabola. However, independently fabricated parallel configurations provide advantages in both cost and performance. This article explores why you should consider the parallel configuration first.
