Stilb
|
CGS unit of luminance. Symbol sb. In the International System of Units (SI), the unit of luminance is the candela per m2 , also known as the nit (symbol nt). One nit is the luminance of a surface of a light source with uniform luminance and an area of 1 m2 when the vertical luminous intensity is 1 candela, while a stilb is 104 times that amount, i.e. 1sb = 1cd/ cm2 = 10,000cd/ m2 = 10,000nt. → Related article Lambert Source : Heibonsha Encyclopedia About MyPedia Information |

輝度のCGS単位。単位記号sb。国際単位系（SI）では輝度の単位はカンデラ毎m2で，別名ニト（記号nt）ともいう。１ニトは輝度が一様な面積1m2の光源の，垂直方向の光度が１カンデラであるときのその面の輝度であるが，スチルブはその104倍の大きさ，すなわち1sb＝1cd/cm2＝１万cd/m2＝１万nt。 →関連項目ランバート 出典 株式会社平凡社百科事典マイペディアについて 情報 |
