Product introduction： Eachwave can provides various specifications of off - axis parabolic mirrors √ Use aluminum film substrate reflectors √ Available at 15°, 30°, 45°, 60° or 90° off-axis √ Select aluminum, silver and gold film Different from the standard parabolic mirror, the off-axis parabolic film mirror can direct and focus the incident parallel light at a specific Angle, and support the infinite-distance focus. These mirrors are commonly used as parallel light tubes in Schlieren and MTF systems, while gold-coated off-axis parabolic mirrors are used in FLIR test systems. Note: Due to the 175Å surface roughness, this MIRROR is not suitable for visible and UV applications that require low scattering.

1. The diameter  An off-axis parabolic metal mirror is usually a prototype, and the diameter is the external dimension. A 1-inch (25.4mm) off-axis mirror is cut from a 1-inch cylindrical metal, and a 2-inch off-axis mirror has a 2-inch (50.4mm) diameter bottom surface. 2. Focal length (female focal length, effective focal length) The FOCAL length OF AN off-axis parabOLIC MIRROR IS divided into PARENT FOCAL LENGTH and EFFECTIVE FOCAL length. The default focal length is the effective focal length, which is also defined in inches. The focal length of standard off-axis mirrors is 1 inch, 2 inches, 3 inches, 4 inches, and 6 inches. 3. The off-axis Angle The off-axis Angle is an index reflecting the propagation direction of the beam through the off-axis parabolic mirror. The off-axis Angle of the metal mirror is generally 90°. For the off-axis parabolic mirror with an off-axis Angle of 90°, the propagation axis of the collimated beam should be perpendicular to the base, so as to achieve the ideal focusing effect. Other off-axis angles can also be set if the design is special. 4. The coating Generally for gold plating film, silver plating film and aluminum plating film. There are also special coatings, such as UV-enhanced aluminum. (as shown in the picture below) 5. Determine whether to drill holes Off-axis parabolic mirrors with small holes mainly analyze excitation signals (laser or electron beams) and terahertz waves, e.g. 1) where two beams of light are required to travel collinear in space; 2) Where the central beam or electron beam needs to be kept from reflecting. The base of these mirrors has a central hole through which a beam of light can travel collinear with the beam focused by the mirror's parabolic reflection.
