直流安定化電源で、正負両出力、リップル電圧 3 mVp-p以下、電流容量 100 mA以上のものを推奨します。なお、単出力電源では動作しません。スイッチング電源やDC-DCコンバータを使う場合は測定に影響が出ないようなリップル対策やノイズ対策を行ってください。
C6386-01のデータシートでは、λp=830 nmのLED光源を使用した場合の受光感度を表示しています。受光感度の単位を「mV/lx」に変更するためには、色温度 2856 Kの標準タングステン電球を使用した場合に換算します。換算後の値は、以下のようになります。
|H レンジ||30 mV/μW||→||1.57 mV/lx|
|M レンジ||3 mV/μW||→||0.157 mV/lx|
|L レンジ||0.3 mV/μW||→||0.0157 mV/lx|
シールド効果を目的とするため低ノイズ同軸ケーブルを推奨します。ケーブル特性インピーダンス 50 Ωまたは75 Ωの一般市販品のBNCケーブルを使用できます。
3 m以下のものを推奨します。これ以上に長い場合には、ノイズの原因となります。3 m以上で使用したい場合は、お近くの営業所までお問い合わせください。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.

Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
