Leitz illuminating attachment instructions manual user1. Introduction The illuminating attachment serves for the change of the lighting intensity. the colour characteristics, and the co- lour temperature. These three parameters are important in microscopy and especially in photomicrography. In ad- dition. the illuminating attachment ensures a particularly even illumination of the image field even when the light source is off-centre. 1=1-££311t398-i.r1'9931fy The lighting intensity can be reduced continuously and re- producibly with purely optical means without effecting the colour temperature. intensity adjustment through the lamp current. which at the same time changes the colour tem- perature. is not necessary. 1:3-99199ifi9539‘35‘3‘919 The required colour temperature can be set reproducibly on the illuminating attachment independently of the lamp current.
