【摘要】：為了解決ZEMAX軟件擬合計(jì)算折射率溫度系數(shù)經(jīng)驗(yàn)公式常量時(shí),參量回歸計(jì)算的折射率和折射率溫度系數(shù)與實(shí)驗(yàn)值存在較大偏差的問題,用1stOpt差分進(jìn)化法求解折射率溫度系數(shù)經(jīng)驗(yàn)公式常量.以氟冕D-FK61和特種火石H-TF3A光學(xué)玻璃為例,用該方法求解的λtk常量與其通用數(shù)值范圍0.08~0.33相吻合,參量回歸計(jì)算的折射率和折射率溫度系數(shù)與實(shí)測(cè)值的偏差分別小于1×10~(-5)、2×10~(-7)/℃.該方法作為ZEMAX軟件計(jì)算光學(xué)玻璃折射率溫度系數(shù)的有效補(bǔ)充,計(jì)算的準(zhǔn)確性高,可為熱補(bǔ)償光學(xué)系統(tǒng)設(shè)計(jì)提供準(zhǔn)確的光學(xué)參量保障.
[Abstract]:In order to solve the problem that the refractive index and the temperature coefficient of refractive index calculated by parametric regression are deviated from the experimental values when the empirical formula of temperature coefficient of refractive index is fitted by ZEMAX software. The empirical formula constant of refractive index temperature coefficient is solved by 1stOpt differential evolution method. Taking fluorine coronal D-FK61 and special flint H-TF3A optical glass as examples, the 位 tk constant calculated by this method is in agreement with its general numerical range of 0.08 ~ 0.33. The deviations of refractive index and refractive index temperature coefficient calculated by parametric regression are less than 1 脳 10 ~ (-5) and 2 脳 10 ~ (-7) / 鈩，
