Third, VR that can be seen in the corrected state without wearing glasses, development of aspherical correction lens and antifog coating with excellent optical superiority.
ガラス3枚、φ80mmの精度の高いグラスモールド非球面レンズを含む非球面レンズを3枚使用。
and 3 aspherical lens elements, including an φ80mm high precision molded glass aspherical element.
Minimized chromatic aberrations-thanks to FLD and SLD glass lenses. FLD glass SLD glass ASPHERICAL LENS One of the requirements of high rendering performance is the correction of chromatic aberration.
The use of an aspherical element, XLD(Extra Low Dispersion)* lens, and advanced optical design technology delivers high image quality that is compatible with 3 mega-pixel cameras.
The beauty of this shop is that you will be able to buy a set of eyeglasses(which includes frame, thin aspheric lens, and case) with thin aspheric lenses for the list price.
The"Double-sided Aspheric design" first developed by SEIKO ensures a sharp, clear field of vision from edge to edge of the lens with little distortion or blurring.
The use of an aspherical element, XLD(Extra Low Dispersion)* lens, and advanced optical design technology delivers high image quality that is compatible with 3 mega-pixel cameras, qualifies full HD 1080p.
To produce the segments, Canon is drawing on its various optical technologies cultivated through the manufacture of lenses and mirrors, namely grinding and polishing technologies, aspherical surface processing technologies, and measuring technologies.
To achieve a thin aspheric design using plastic material, firstly, a prototype lens with an aspheric design and a low base curve(high degree of flatness) was produced.
In the grinding and polishing method, we use a whetstone, which is a tool incorporating diamonds. The whetstone grinds the lens material as it turns so as to carve out the complex shape of the required aspherical surface.
With a focus on advancing Edmund Optics' manufacturing capabilities, EO adds magneto-rheological finishing(MRF) and aspheric manufacturing to its growing toolbox.
According to the company, the lens includes a unique, bi-aspherical design that uses 15% more of the image sensor than Moment's fisheye 15mm(previously called Superfish Lens).
In addition to a unique, newly developed lens construction, glass with high refractive index and low dispersion qualities were used, along with optimized placement of aspherical high-precision molded glass lenses for aberration removal to the utmost limits, even image quality and contrast from the center to the edges of the image, and high resolution.
Employing two LD(Low Dispersion) elements, three Molded-Glass Aspherical elements, one XR(Extra Refractive Index) element, and one Hybrid Aspherical element, the lens delivers astounding image quality by reducing aberrations to a bare minimum.
DESCRIPTION The use of a focused ion beam of a diameter of about 0,1 μm makes it possible to bore microscopic holes at high accuracy, to sharpen various types of probe, and to process and modify aspheric surface lenses.
Thanks to the adoption of a large-diameter aspherical lens and a new focus/zoom system, the Premista achieves stunning optical quality from the center to the corners, allowing the cinematographer to capture the feeling and texture of the subjects.
CS" can handle to the various device shapes of ball lens, aspherical lens, stems, and leads, etc. as the standard. Furthermore,"CS" achieves high-accuracy seal with the option of active alignment function, etc.
The new lens incorporates aspherical and UD lenses(ultra low dispersion), it suppress the incidence of chromatic aberrations(produced the more increases the size of the lens aperture) and facilitate the design of a compact objective.
To achieve this, related ultra high precision technologies including molding materials, ultra high precision mold process methods, aspherical surface measurement methods, glass press processes, the glass material for press as well as an aspherical lens design method, were newly developed.
ULG, LG Series| TOSHIBA MACHINE The ULC/ULG series has been developed with the goal of turning and grinding free-form surface(f-θ lens) and aspheric lenses as well as their respective molds with high efficiency and high precision.
