style="text-indent:25px">精密光學(xué)平臺(tái)較主要的一個(gè)目標(biāo)是消除平臺(tái)上任意兩個(gè)以上部件之間的相對(duì)位移。精密光學(xué)平臺(tái)或面包板較重要的特性為其共振頻率。共振頻率和振幅是負(fù)相關(guān)的，因此共振頻率應(yīng)盡可能地增大，從而將振動(dòng)強(qiáng)度較小化。平臺(tái)和面包板會(huì)在一個(gè)特定的頻率范圍內(nèi)發(fā)生振動(dòng)。為了改善性能，每種尺寸的平臺(tái)和面包板的阻尼效果都需要進(jìn)行優(yōu)化。平臺(tái)阻尼需要進(jìn)行各種測(cè)試，對(duì)其厚度/面積的比值進(jìn)行優(yōu)化。更大面積的平臺(tái)（邊長(zhǎng)至少為10英尺或3米）具有厚度為12.2英寸（310毫米）的標(biāo)準(zhǔn)厚度，這樣可以提高穩(wěn)定性。上海氣浮光學(xué)平臺(tái)設(shè)計(jì)平臺(tái)和面包板設(shè)計(jì)還可以采用大半徑圓角，這樣能減少實(shí)驗(yàn)室中的尖銳邊緣，提高安全性。</p><div

光學(xué)平臺(tái)的硬重比對(duì)于其共振頻率有著重要的影響。較高的硬重比可以提高平臺(tái)的共振頻率，從而降低其在外界影響下的振動(dòng)。而且在外力作用下，具有較高硬重比的平臺(tái)可以在較小的重量下產(chǎn)生比較小的變形，增加系統(tǒng)內(nèi)部的剛性。內(nèi)部采用蜂窩狀支撐結(jié)構(gòu)的光學(xué)平臺(tái)可以充分的提高硬重比，達(dá)到提高系統(tǒng)性能的目的。光學(xué)平臺(tái)使用注意事項(xiàng)有哪些呢？光學(xué)平臺(tái)使用時(shí)請(qǐng)勿用酸性液體清洗本產(chǎn)品，以免破壞產(chǎn)品表面質(zhì)量，請(qǐng)勿將本產(chǎn)品放置在高溫、潮濕及強(qiáng)度振源處，請(qǐng)勿用水沖洗本產(chǎn)品，本產(chǎn)品長(zhǎng)時(shí)間處于一種狀態(tài)下，請(qǐng)用水平儀調(diào)整臺(tái)面水平，工作臺(tái)面上擱置的任何設(shè)備或工具，都必須小心輕放，盡量不要相對(duì)磨擦，以避免損傷工作臺(tái)面，降低使用精度。工作臺(tái)面安裝孔，是用于固定設(shè)備的M6螺孔，使用時(shí)避免用力過大，影響工作臺(tái)精度。
