Fabrication of optical components has not changed significantly in the past century, and is based on mechanical grinding, machining and polishing that rely on complex and expensive infrastructure. Furthermore, such mechanical methods present challenges in the fabrication of large or geometrically complex components.
Precision truing and grinding experiments were performed on an ultra-precision grinding machine (Moore Nanotech 350 FG). The basic experimental configuration is presented in Fig. 8.A diamond grinding wheel with a roughly shaped arc profile was mounted on a high-speed grinding spindle, which moved in the Z-axis direction.A GC truing wheel was mounted on a …
1. Introduction. The water-repellent (hydrophobic or superhydrophobic) surfaces have been widely found in nature including the lotus leaves [1,2], flower petals [3,4], nepenthes [5,6], butterfly wings [7,8], insects compound eyes [9,10], water-strider legs [11,12], etc.These functional surfaces have recently drawn great attention owing to the potential utility in the …
In theory, the process requires a minimum of three parts. The actual number is determined by part quantity, part size, and machine size. With double-sided lapping and polishing (DSLP), the optical components are held in geared or sprocketed carriers that are driven in a planetary motion covering the full surface of the lapping plates and are subject to continually changing …

Grinding wheels come in many different sizes, shapes, and abrasives (Figure 5-7). Some of the various types are listed below. Straight Straight wheels, numbers 1, 5, and 7, are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and offhand grinding and snagging. The recesses in type
Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the …
It is mainly used in many optical devices such as telpes and optical cavities require a substrate ... In short it is an extension of grinding. This is also called the 'hypothesis of abrasion'. The other theory is ... is flat it will remain flat for long periods (e.g., months). Here same abrasives are used as the ones for pitch
Optical cavities offer a possible solution, according to the Birmingham team, since resonant power enhancement in such cavities reduces the required input power, although at the kilometer-scale maintaining desired pulse length will remain difficult. Meeting the …
Optical fiber lens, is a kind of special optical fiber. It is made by grinding the tip of the fiber into the shape of a certain lens such as angle-polished, wedge-shaped, and tapered. The optical fiber lens is used to minimize the spot size, change the optical path, or transform the optical mode in the optical system.
ConspectusConventionally, the virtue of porosity is only given to porous solids. Metal Organic Frameworks (MOFs), carbon materials, or zeolites are some examples. However, processing these solids is not a straightforward task. Here, we discuss how to endow porous solids (MOFs) with liquid phase processability. More specifically, we show that surface modification of MOF …
These polynomials remain common surface descriptors of freeform surfaces and enable, for example, variable optical functions when used in pairs [7-10]. However their lack of orthogonality renders them less desirable than their orthogonal counterparts for …
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
ND Filters. A neutral density filter (ND filter) is a filter of uniform density that attenuates light of all colors equally. An ND filter is used to allow a longer exposure (to create blur) or larger aperture (for selective focus) than otherwise required for correct exposure in the prevailing light conditions, without changing the tonal balance of the photograph.
