Description:Parabolic mirrors offer excellent correction of spherical aberrations, and are available in both on-axis and off-axis specifications. On-axis parabolic mirrors produce collimated reflected light, while off-axis parabolic mirrors focus reflect light to a focal point off-axis. These products can be supplied in a variety of materials, including BK7 glass, copper, fused silica, UV grade fused silica, nickel, and optical crown glass. Common coatings for parabolic mirrors include none (uncoated), enhanced aluminum, protected aluminum, dielectric, protected gold, and silver. We specialize in the production of medium to large-size custom mirrors with exacting tolerances, high grade surface finishes and difficult coatings. The surface accuracy is verified on a Zygo or Wyko interferometer. Please send us your specification or drawing and we will be happy to return a quotation ASAP. Our average response time is within 24 hours. Our optical designers are always available to assist with your special needs and our factory in China is ready to meet your quantity requirements.
