Makowsky KATOPTARon LDM-1(s), 1998 onwards

Dr. Helmut Makowsky, Opt. Ger?te, Troisdorf near Cologne. No. 1834, 11/800 mm mirror lens with iris diaphragm, based on his Katoptaron "Schiefspiegler" lens design consisting of two quartz ZERODUR Schott glasses, UV-IR transmission (approx. 200 nm to 4000 nm), from infinity to approx. 3 meters for very high magnifications, knob on the back for fine mirror adjustment depending on the scale, higher magnifications possible with screw-on achromatic lenses, camera connection via T2 adapter, and an additional camera connection for a second camera, where a pivoting beam splitter with illumination attachment, filter insert, and iris diaphragm can be used to project illumination onto the macro object. Very rare to find, as it cost $8,500 new at the time.

布雷克拍品等级是为了方便竞买人判断拍卖品的成色而设置的。布雷克等级用1到6级来标注外观和功能的成色，(从非常好到非常差)。 在目录图册里用括号里的2个数字来表示，前一个数字表示外观成色的级别，后一个数字表示功能成色的级别。如(3/2)表示外观成色是3(满意的)，功能成色2(好)。 成色 定义参照下列标准： 1 - 非常好 (未使用过，没有使用痕迹) 2 - 好 (新，极少的使用痕迹) 3 - 满意的 (普通的使用痕迹) 4 - 及格的 (明显的使用痕迹，某个非主要部件是后配的) 5 - 有缺陷的 (极明显的使用痕迹, 某个主要部件是后配的，功能上有缺陷，需要修理) 6 - 非常差 (严重破损, 缺少重要部件)
