主要仕様等
BaSO4積分球(1 / 11 ページ) 主要仕様1602
①名称:硫酸バリウム積分球
②特徴:可視から近赤外まで反射率が高く、広く用いられているが、
親水性で、水蒸気吸収帯では分光放射輝度が下がること。
③内径:1m
④開口径:36cm
⑤開口中心高さ:標準112.5cm(脚の上げ下げで±10cm調整可能)
⑥内面:硫酸バリウム
⑦光源: ハロゲンランプ 600W×5灯 (GE Lighting, Quartzline Lamp, FFJ (120V))、
150W×4灯 (EIKO Q150T4/CL/25 (25V))
( 上記以外の150W×8灯およびXeランプ (1000W×2)は非運用)
⑧波長範囲: 360~2300nm
⑨放射輝度: 約 8~1400 W/m2/sr/μm at 1000nm
⑩入力電圧: 3相 200VAC
⑪運用開始:2001年
⑫モニタ:5ch(nm);490,666,865,1640,2210
⑬本体製作:
Labsphere Inc.(USA)((株)システムズエンジニアリング)

BaSO4積分球(6 / 11 ページ) 角度むら1507
① ② ③ ④ 可視域(380nmを除く)では、中心から角度範囲±2.5°において、±0.5%以内の変動で安定している。
ランプ点灯位置に関係なく、同じ変動傾向が見られる。
輝度むら分布のX軸、Y軸上の結果とおおむね連動している。
380nmや2210nmでは、素材の反射率が低いため、角度むらが大きくなっている。

例えば、Up(上)は積分球開口面の中心を上から下へ、Left(左)は同じく左から右へ、それぞれ見ている。
