Parabolic Mirrors

The parabolic reflector can completely converge the parallel light along the parallel optical axis to the focus, with zero spherical aberration, which can eliminate the phase delay and absorption loss of the transmission optical element; the base material is generally metal aluminum, and a CNC ultra-precision free-form surface processing machine is used. Using single-point diamond tools, under precise control of machine tools and processing environments, ultra-high-precision machining in the plastic domain of paraboloids is achieved, and mirror surfaces that meet optical quality requirements are directly processed, with surface shape accuracy ≤0.1 micron and surface roughness Ra ≤0.01 micron.

Features of Parabolic Mirrors

Features of Parabolic Mirrors
  • One-stop customized production: Solar Valley processes various parabolic reflectors with plano-concave, bi-concave, and convex-concave structures according to customer requirements. Parabolic reflectors can be round, D-shaped, square, or trapezoidal. and other structures.

  • Material: Use aluminum 6061-T6 and other metal substrates.

  • Parabolic mirror properties: The enhanced metal coating can achieve high reflectivity in the deep ultraviolet (DUV) and visible spectral ranges, with an average reflectivity of greater than 96% in the broadband range of 800 nm - 20 µm. It is an ideal choice for building solar mirrors. One of the commonly used components in Hertzian light paths and infrared light paths. It is based on the principle of geometric paraboloids and can focus parallel incident collimated beams/collimated THz waves onto the focus. It can also focus terahertz waves or infrared light emitted by point light sources. Converted into parallel transmitted beams. Product specification description: 1. Maximum outer dimension of circular parabolic reflector: OD≤φ300mm 2. Maximum outer dimension of square parabolic reflector: ≤254×254mm 3. Parabolic reflector can reach the following accuracy level according to customer requirements: Ultra-high precision level : Surface error <0.1μm, surface roughness <0.01μm High precision grade: Surface error <0.5μm, surface roughness <0.05μm Precision grade: Surface error <1μm, surface roughness <0.1μm

  • Surface defect level: 60-40, 40-20, 20-10 Produced according to customer requirements.

  • Coating: Gold plating, silver film, aluminum film, or UV-enhanced aluminum film, coating according to customer requirements
