A cylindrical lens used in many industries is typically used to focus, condense or expand incoming light. A cylindrical optical lens has one cylindrical surface, causing light to be focussed in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical optical lenses are technically more difficult to manufacture than spherical or flat lenses which is why BRD Optical uses state-of-the-art polishing techniques alongside stringent lens assessment to manufacture each lens. The cylindrical optical lenses are typically rectangular, square, or circular and of either a plano-convex or plano-concave design. BRD Optical's cylindrical optical lenses combine low wedge with high surface accuracy. As one of the best optical components manufacturers, we assess the quality of each individual lens using Trioptics centration measurement and a Zygo GPI interferometer. All BRD Optical lenses are available both uncoated or coated with a broad range of high durability, low loss AR coatings, and can be manufactured to 20-10 surface roughness. Here are the different types of cylindrical lenses, such as plano concave cylindrical lens, plano convex cylindrical lens and achromatic cylindrical lens. Optical Cylindrical Lens Applications Cylindrical optics lens can converge or diverge light beams in a single axis. Cylindrical lens is used in many industries and fields such as optical metrology, laser scanning, spectroscopy, laser diode output beam shaping, and light-sheet illumination microscopic imaging. Form the collimated light source into a line light source This is the most widely used cylindrical lens. Taking a plano-concave cylindrical lens as an example, it can be a beam of collimated light that expands into a linear light source according to the magnification. There is also cylinder lens for astigmatism. Collimation of diode output beam The output beam of the laser diode diverges in an asymmetrical form, and its collimation work is more challenging. For example, for a diode light source with a divergence angle, if only a standard spherical lens is used, it can only be collimated in a single direction, and divergence or convergence will occur in the other direction. Using cylindrical optical mirror can decompose the problem into two one-dimensional directions. By combining two orthogonal cylindrical mirrors, the two directions can be collimated simultaneously. Optical Cylindrical Lens FAQS What Is Difference Between Spherical And Cylindrical Lens?What Is Difference Between Spherical And Cylindrical Lens? Spherical lenses are lenses taken out from a sphere such as a ball. Where as, cylindrical lenses are lenses taken out from a surface of a cylinder like a tumbler. Cylindrical lenses have an axis associated with them. Both, spherical and cylindrical power can keep changing through life. What Does A Cylindrical Lens Do?What Does A Cylindrical Lens Do?

NATURAL FERULIC ACID Botanical Source: Rice Bran CAS.: 1135-24-6 Specification: 40%~99% by HPLC Appearance: White or light yellow crystalline powder Solubility: Freely soluble in ethanol, and slightly soluble in hot water Package: 1kg/foil bag, or 20kg/drum   Basic Information Trans-Ferulic acid is a highly abundant phenolic phytochemical which is present in plant cell walls. trans-Ferulic acid is a phenolic acid that can be absorbed by the small intestine and excreted through the urine. It is one of the most abundant phenolic acids in plants, varying from 5 g/Kg in wheat bran to 9 g/kg in sugar-beet pulp and 50 g/kg in corn kernel. It occurs primarily in seeds and leaves both in its free form (rarely) and covalently linked to lignin and other biopolymers. It is usually found as ester cross-links with polysaccharides in the cell wall, such as arabinoxylans in grasses, pectin in spinach and sugar beet and xyloglucans in bamboo. It also can cross-link with proteins. Due to its phenolic nucleus and an extended side chain conjugation (carbohydrates and proteins), it readily forms a resonance stabilized phenoxy radical which accounts for its potent antioxidant potential. Food supplementation with curcuminand ferulic acid is considered a nutritional approach to reduce oxidative damage and amyloid pathology in Alzheimer disease.  https://www.xa-gs.com/products/natur , al-ferulic-acid.html Physical Analysis Items Standards Results Description Off-white to white powder complies Assay 98% 98.31% Mesh Size 100% pass 80 mesh Complies Ash ≤5.0% 2.85% Loss on Drying ≤5.0% 2.85%   Chemical Analysis Items Standards Results Heavy Metal ≤10.0mg/kg Complies Pb ≤2.0mg/kg Complies As ≤1.0mg/kg Complies Hg ≤0.1mg/kg Complies   Microbiological Analysis Items Standards Results Residue of Pesticide Negative Negative Total Plate Count ≤1000ctu/g Complies Yeast&mold ≤1000ctu/g Complies E.coil Negative Negative Salmonella Negative Negative   Brief Introduction Rice bran extract is prepared from the rice husk. The main ingredient of rice bran extract, Ferulic acid is an antioxidant which neutralizes free radicals that could cause oxidative damage of cell membranes and DNA. Rice bran extract, ferulic acid helps to prevent damage to our cells caused by ultraviolet light. Ferulic acid is often added as ingredient of anti-aging supplements.   Main functions • Antioxidant effect • Prevention of food discoloration • Cosmetic effect, skin whitening, photo-protection • Growth and brain function enhancing effect • Inhibitory effect of carcinogenesis of colorectal cancer • Blood sugar and pressure lowering effect   Medical field Anti-Inflammatory Agents, Non-Steroidal Anti-inflammatory agents that are non-steroidal in nature. In addition to anti- inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. Cholagogues and Choleretics Gastrointestinal agents that stimulate the flow of bile into the duodenum (cholagogues) or stimulate the production of bile by the liver (choleretic). Anticoagulants Agents that prevent BLOOD CLOTTING Antihypertensive Agents Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS.
