ライツの 「マイケルソン」と「ミロー」干渉計アッタチメントです。

Leitz Michelson and Millow's interferometer attachments

1970年代の製造品



「マイケルソン」と「ミロー」干渉計アッタチメントは落射型の偏光顕微鏡で使用するアクセサリーです。

対物レンズに装着するライツの干渉計アタッチメント(2種類)。

(画像3枚目を参照)

左側がマイケルソンの干渉計

右側がミローの干渉計



対物レンズを偏光顕微鏡の「対物レンズ用クラッチ」に装着します。

(画像6~8枚目を参照)

20倍と32倍の2本の対物レンズはRMSネジ標準規格品ですので、ライツ社以外の偏光顕微鏡にも装着できます。

マイケルソン干渉計のアタッチメントには、20倍の落射用対物レンズが指定されます。



ミロー干渉計のアタッチメントの分解

(画像13枚目を参照)

ミロー干渉計には、20倍と32倍の落射用対物レンズが指定されます。



ミロー干渉計には6種類のインサートがあります。

(画像15枚目を参照)

適当なインサートをアタッチメントに装着して使います。



マイケルソン干渉計は表面の黒いギヤのようなダイヤルを回転すると、標本上に3か所の黒い●の影が現れて干渉縞を見つけやすくなります。(画像16枚目を参照)



ライツ偏光顕微鏡「オルトプラン Pol」 に装填したマイケルソン干渉計(画像18枚目を参照)

※出品内容に顕微鏡は含みません。



干渉縞が現れた様子の画像。

(画像19枚目を参照)

一見平らに見える鏡のようなCDの表面でも、凸凹している箇所があると干渉縞が現れます。

干渉縞の間隔(黄色の矢印)を測定してキズやヘコミの凹凸の深さ(高さ)を測定します。

顕微鏡で数十ナノメーターレベルでの凹凸の測定が可能だったと記憶していますが、正直正しい使い方を理解しているというわけではありません。



【干渉計アタッチメント(2種類)はライツ社のRMSネジ企画の対物レンズ(2種類)に装着して使用します。偏光顕微鏡で観察する際は防振台の使用をお勧めします。どちらの干渉計アタッチメントも保管状態が良好なレアアイテムです。】
