For Stands V and VI, which are not equipped with the ABBE Illuminating 

 Apparatus, we supply suitable condensers and iris-diaphragms in another form. 

 These are as follows: 



a. For Stand V. 



\<>. 37. *Simplified Illuminating Apparatus with condenser system 

 num. Ap. 1.20 in sliding tube with centrally fitted iris-diaphragm. It is inserted 

 into the fixed sliding sleeve similarly as in the apparatus No. 38 and 3805 from 

 below the stage. 



No. 38. *Simplified Illuminating Apparatus with swing-out con- 

 denser num. Ap. 1.20 and centrally fitted iris-diaphragm. The condenser proper 

 is the same as in the apparatus No. 41. See p. 34. 



Xo. 3805. *Simplified Illuminating Apparatus with condenser system 

 num. Ap. 1.20 and centrally fitted iris-diaphragm. 



To the condenser system or to the iris-diaphragm of apparatus No. 3805 

 can the under part of the Polariser II No. 161 be attached. See p. 54. 



Besides the condensers with centrally fitted iris-diaphragm, specified under Nos. 

 37, 38 and 3805, there can be also inserted into the sliding sleeve of Stand V the cylinder- 

 diaphragm No. 21 and the iris-cylinder diaphragm No. 22. On the other hand the achro- 

 matic condensers, the centring device for objectives, the star-disc and central stops No. 

 24 a, b for dark-ground illumination, the Polariser No. 160, the apparatus f or illumination 

 with spectral analysed light can not bo used on Stand V. 



No. 3810. Iris-diaphragm for the simplified Illuminating Apparatus 

 No. 3805. We supply this iris-diaphragm also alone, since when employing 

 Polariser Xo. 161 it can be inserted between the condenser system and the 

 NICOL'S prism.
