Carl Zeiss (1816-1888) produced optical instruments starting in the 1840s at his factory, Carl Zeiss Jena (today Carl Zeiss AG). Here he produced his Stand I-compound model microscope of 1857. He later worked closely with the glass-paste chemist Otto Schott, and the physicist-optical scientist Ernst Abbe (1840-1905), a co-partner in Carl Zeiss AG. The enhanced lighting accessories, such as the condenser of late-nineteenth century fully "bacteriological microscopes" - and also the improved oil immersion of specimens - are all accredited to Abbe by contemporary authorities such as CF: 28-32.
