Developed by Zeiss in 1933, designed and prototyped in 1946, modeled after an L-shaped microscope, and completed in 1947. The well-balanced design has long been a favorite in high-end microscopes in terms of function, lens performance, and usability, and has also had an important impact on many new microscopes developed later.

This configuration is based on the fact that the coarse and fine movement devices, which were conventionally located on the upper part of the However, since the eyepiece is located at the position of the eye because of the L-shape, it has a great feature that it is possible to perform microscopic examination in an easy posture. Revolver

The slide type can be attached and detached with the objectives attached. The stage is a circular double-type automatic rotating type (M), square Types of ten-type automatic rotation type (Gr), square-type ten automatic installation type (G), and simple circular rotation type (D) were prepared. Fine movement The movement is smooth by a Meyer-type mechanism with a vertical movement of 2 mm, a sensitivity of 0.001 mm and a sensitivity of 0,0005 mm.

Is 50mm wide and can be observed from ordinary specimens to large culture bottles. The lighting device is upgraded to Appe complete lighting device (C). Lanart N.A.1.4 condenser type and simplified N.A.1,2 condenser (T) type, lens barrel tilted 45 degrees

It has a multi-function that can rotate 360 degrees at a corner. The photograph shows the binocular tube Lbi, but the trinocular tube Ltr has been developed and the sample is binocular.

And you can take photos. It was later used as the first phase contrast microscope in Japan Was. At that time, there was no other microscope of this type, so demand was high and production was too late.

1933年にツァイスが開発しＬ型顕微鏡を模範に1946年に設計試作、翌1947年に完成。バランスのとれたデザインは、機能、レンズ性能、使用感共に高級顕微鏡の先達として永年にわたって各方面に愛用され、また後から開発される多数の新型顕微鏡にも重要な影響を及ぼしている。

この形は従来鏡台の上部にあった粗動、微動装置をそれぞれステージの下部に位置させたことと、基鏡がＬ型のため接眼部が眼の位置にくるので、楽な姿勢で鏡検できる大きな特徴を持っている。レボルバーはスライド式となり対物ンズを取り付けたまま着脱できる。ステージは円形複式十自動回転式（Ｍ）、角型十自動回転式（Ｇr）、角型十自動組込式（Ｇ）、簡易式円形回転式（Ｄ）、の種類が準備された。微動装置は上下動２mm、１目0,001ｍｍ感度0,0005mmのマイヤー式機構で円滑に動作し、粗動装置の上下動は50mmと広く普通の標本から大型培養瓶まで観察できる。照光装置はアッペ完全照光装置（Ｃ）にアプラナートN.A.1.4のコンデンサのものと、簡易型のN.A.1,2コンデンサ（Ｔ）に区分され、鏡筒は45度の傾斜角で360度回転できる多機能をもつ。写真は双眼鏡筒Ｌｂｉですが、三眼鏡筒Ｌｔｒが開発され標本が両眼で見られるようになり写真撮影も出来るようになる。その後、国産初の位相差顕微鏡としても活用された。当時このタイプの顕微鏡は他になかったため需要が多く、生産が間に合わない状態であった。
