Parabolic Mirror
Parabolic mirrors offer excellent correction of spherical aberrations, and are availablein both on-axis and off-axis specifications. On-axis parabolic mirrors producecollimated reflected light, while off-axis parabolic mirrors focus reflectlight 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. Commoncoatings for parabolic mirrors include none (uncoated), enhanced aluminum, protectedaluminum, dielectric, protected gold, and silver.We specialize in the production of medium to large-size custom mirrors with exactingtolerances, high grade surface finishes and difficult coatings. The surface accuracyis 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 designersare always available to assist with your special needs and our factory in Chinais ready to meet your quantity requirements.Specifications:1) Diameter: Φ25.4 - 1000mm2) Material: BK7 (K9), or as requested3) Surface quality: up to 10-5 S&D, or as requested4) Surface accuracy: up to λ/20, or as requested5) Clear aperture: >90%6) Diameter tolerance: +(0.1-2)/-0.0mm (depends on dimension)7) Focal length tolerance: ±1 - 1.5% (depends on dimension)8) Edge thickness tolerance: +0/-10%, or as requested9) Bevel: (0.1 - 2mm) x 45° (depends on dimension)10) Coating: as requested
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded. The selection of a window should consider the properties of the different optical
This kind of lens is used to increase focal lengths in existing systems. It is more suitable than equi-concave lens if the magnification lies in the range m0.2.We specialize in the production of mediu
All our achromatic doublets are computer optimized to minimize aberrations and coma, and are supplied either multilayer coated or with a single layer anti-reflection coating suitable for the ultra-vio
These lenses have a large range of lengths and are the optimum shape for producingreal images at 1:1 magnification. In a single lens application you should considerusing them in preference to a single
Our ED apochromats use a very high homogeneity ED glass as the center element, fullmulti-coatings on all required surfaces, a fully temperature compensated lenscell, and zonal correcting non-equal int
Ellipsoidal mirrors have two conjugate foci. Light from one focus passes throughthe other after reflection. Ellipsoids collect a much higher fraction of total emittedlight than a spherical mirror or c

Flat mirrors are smooth and highly polished. The flat surfaces are used for reflecting light. The actual reflecting surface is usually a thin coating of silver, aluminum, or other material. They may b
