Aspherical lens Aspherical lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.    Our aspheric lenses are made by grinding & polishing. So they are more precise than traditional mould pressed. And also the tooling cost for grinding & polishign would be cheap and small quantity order would be accept.   We can offer Precision Polished Aspheric Lenses Aspheric Condenser Lenses Aspheric Cylindrical lenses ect.   Specifacation of Aspherical Lens   Size range The focal length range Wavelength range High precision aspheric lens 10-50mm 7.5-50mm 0.4-1.6 UV fused quartz aspheric lens 10-50mm 8-60mm 0.2-2.2 Best form aspherical lens 25mm 25-100mm 0.532-1.064 Achromatic aspheric lens 9-25mm 12-50mm 0.4-0.7 Plastic aspheric lens 10-25.4mm 6.35-254mm 0.4-1.2 Small diameter aspheric lens 1.8-9.9mm 0.7-22mm 0.4-1.6 Small diameter infrared aspheric lens 3.5-6.5mm 1.5-4mm 2-14 Zinc selenide aspheric lens 25.4-50.8mm 12.7-50.8mm 0.6-16 Silicon aspheric lens 25-50mm 25-50mm 1.2-7 IG6 aspheric lens 25-50mm 12.5-50mm 0.9-13 Germanium aspheric lens 25mm 12.5-100mm 2-16 Aspheric cylindrical lens 25mm 20-50mm 0.4-1.6

Micro Light-guide Prism Micro light-guide prism are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense. Dove prisms have an interesting property - when they are rotated along their longitudinal axis, the transmitted image rotates at twice the rate of the prism. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it performs as a right-angle prism.   Used in Interferometry, Astronomy and Pattern Recognition.

Micro Ball Lens 1mm Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling.   Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request. Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.

Custom Sapphire Parts Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.   Sapphire Windows General Specifications   Diameter  0.2-300mm or customization Diameter tolerance  +/-0.1mm or +/-0.02mm Thickness  0.10-100mm Thickness tolerance  ± 0.1mm or +/-0.02mm Surface quality (scratch & dig)  60/40, 40/20 or better Surface accuracy  λ/10, λ/2, λ Clear Aperture  >85%, >90% Parallelism  +/-3' ,+/-30'' Bevel  0.1~0.3mm×45 degree coating  AR, BBAR or upon customer request( UV, VIS, IR)
