Optical components are carefully engineered from semi-transparent material, and are used to transmit or reflect light. Transmissive optical components include lenses, beamsplitters, windows, optical flats, prisms, windows, optical flats, wave plates and fiber optics. Reflectives include mirrors and retroreflectors.
The performance of each optical component depends on substrate and coating used as well as form and finish. Shanghai Optics manufactures high quality optical components from a variety of different optical substrates. These optics have applications in fields ranging from microscopy, medical lasers, and imaging to surveying, interferometry, satellite, and data transfer. Our factories are fully equipped to produce the highest quality precision optics, and state of the art metrology equipment allows us to ensure that every component produced in our factory fully meets all relevant standards.
A singlet lens is formed from a single piece of optical material, but may take any of a number of different shapes or sizes. The basic shapes of these optical components includes:
A best-form lens is considered to be the shape which minimizes spherical aberration. The best-form lens for your application depends on several factors, primarily the conjugate ratio of the system and the index of refraction of the lens material.
A symmetric biconvex lens, with both sides bulging outward, is best form for imaging at unit magnification, where the distance to the object is the same as the image distance. For any material index and wavelength the coma, distortion and lateral chromatic aberration will cancel each other out at this unit magnification.
Singlet lenses are most commonly manufactured from BK7 or Fused Silica, depending on the wavelength required.
We also carry multipart lenses. Achromatic doublet lenses are the best choice for focus on-axis, as they give minimal spherical aberration as well as color correction. Using an achromatic doublet lens will also give you a much smaller focal spot than if you had used singlets.
Optical windows pass electromagnetic radiation from one environment to another, and are typically designed to maximize transmission over a given wavelength range. The ideal substrate for an optical window will depend both on the wavelength transmission desired and the environments on both sides of the window.
Where temperature gradient is high, you will need to choose a window with very high thermal stability. Expected pressure, potential chemical reactions, and environmental abrasion are other factors you will want to consider when choosing your optical windows.
An optical prism is a solid block of optical material. The sides are flat and polished, and meet at precise angles. Optical prisms can be used to invert or rotate images, to deflect or deviate light, or as a beamsplitter, to separate light into its polarization states or component wavelengths.
Shanghai Optics manufactures a wide variety of prism for different optical applications. Some of our most popular prisms include the right angle prism (used to bend light at a ninety degree angle), the dove prism, which rotates an image, and the roof prism, which can both invert an image and deflect light by ninety degrees.
A filter transmits certain wavelengths of light while absorbing or reflecting others. We manufacture long pass, short pass, and band pass filters, as well as UV blocking filters and both cold and hot mirrors.
We also manufacture both polarizing and unpolarizing beam splitters. A beam splitter, as its name suggests, splits a beam into two separate components. Cube prisms are manufactured from two right angle prisms, cemented together along the hypotenuse. They shorten the optical path of the system, and are used with 0 degree angle of incidence. A plate beamsplitter is a thin glass plate, coated on the first surface. These beamsplitters are often optimized for 45 degree angle of incidence.
An optical mirror is used to focus, redirect, and image light. We carry plane, spherical, and pyramidal mirrors in various substrates and with a range of different coatings. Our precision optical mirrors are carefully manufactured to provide optimal surface quality, high clear aperture and very tight tolerances.
A retroreflector is typically formed from three optical surfaces arranged to form a corner, although solid retroreflectors (corner cubes) are made of solid glass. These optics reflect an incident beam onto itself, and are used for making distance measurements as well as for alignment of various laser-based systems.
