Off axis parabolic mirror

Thorlabs' off-axis parabolic mirrors are available with one of four coatings: UV-enhanced aluminum (2- 4nm), protected aluminum (4nm - µm), . Parabolic mirrors have the ability to focus collimated light without introducing spherical aberration. An Off-Axis Parabolic (OAP) mirror is simply a side section of .

Our standard off-axis parabolic mirrors are segments of a full paraboloid with a circular cross sectional aperture. The optical axis is folded 90° and displaced . This allows to avoid comatic aberration (or coma) that would emerge in case of using spherical mirror at an angle. Thorlabs' Off-Axis Parabolic (OAP) Mirrors are first-surface mirrors whose reflective surfaces are equivalent to segments of a parent parabolic mirror.

Standa provides standard and special metal mirrors with parabolic surface contours for off-axis beam focusing performance. Parabolic mirrors are the most common type of aspherical mirrors used in optical instruments. They are free from spherical aberrations, and thus focus the . The parabolic mirrors that are custom made, include the following range: Custom Off-axis parabolic metal mirrors and precision parabolic mirrors: Knight Optical . Click on custom off Axis Parabolic Worksheet to request information. Distance (OAD): Specified along a perpendicular from optical axis to inner edge of mirror.

Off-axis paraboloids are excellent for collimation of a point source and for collecting of light from a distant source. An off-axis parabolic mirror converts plane waves into spherical ones and vice versa with high accuracy. This aspherical mirror is indispensable for . This tutorial will show you how to model an off-axis parabolic mirror.

The concept shown here applies to any decentered surface and is not . Mirrors, made from copper substrates, will withstand extremely high laser powers and industrial environments, providing diffraction . This paper complements our previous study on testing a 25. CLaser develops various off-axis parabolic mirror for very high precision optical system, especially for light sour. Off-Axis Parabolic Mirrors Diamond turned first-surface Aluminum mirrors provide a highly efficient parabolic focus of light in the infrared range.

The focal point is off the mechanical axis, giving full access to the reflector focus area. Unlike standard parabolic mirrors, these mirrors direct and focus incident .
