2.5寸和3寸的玻璃透鏡有什么區(qū)別?
透鏡是用透明物質制成的表面為球面一部分的光學元件,鏡頭是由幾片透鏡組成的,有塑膠透鏡(plastic)和玻璃透鏡(glass)兩種,玻璃透鏡比塑膠貴。通常攝像頭用的鏡頭構造有:1P、2P、1G1P、1G2P、2G2P、4G等,透鏡越多,成本越高。因此一個品質好的攝像頭應該是采用玻璃鏡頭的,其成像效果要比塑膠鏡頭好,在天文、軍事、交通、醫(yī)學、藝術等領域發(fā)揮著重要作用。
Differences Between 2.5-Inch and 3-Inch Glass Lenses 1. Coverage and Performance: o A 3-inch lens provides a wider area of illumination and better overall performance compared to a 2.5-inch lens. ________________________________________ What Are Lenses? Lenses are optical components made of transparent materials, with surfaces shaped as part of a sphere. Lenses can be classified into two types: 1. Plastic Lenses (Plastic): o More cost-effective. o Typically used in low-cost applications. 2. Glass Lenses (Glass): o More expensive but offer superior imaging quality. ________________________________________ Lens Construction in Cameras ? Camera lenses are composed of multiple lenses, with configurations such as: o 1P, 2P, 1G1P, 1G2P, 2G2P, 4G, etc. o 1G/2G: Denotes glass lenses, while P represents plastic lenses. ? As the number of lenses increases, so does the cost and quality. ________________________________________ Advantages of Glass Lenses ? Provide better image quality compared to plastic lenses. ? Widely used in fields requiring high precision, including: o Astronomy. o Military applications. o Transportation. o Medical imaging. o Artistic endeavors. In summary, while 2.5-inch and 3-inch lenses differ primarily in their coverage area, their selection depends on the application requirements, with glass lenses generally offering superior performance and durability.
