INSTRUMENT DESCRIPTIONAxio Vert.A1 Operation and Functional Elements of Optional Components Carl Zeiss05/2012 431030-7044-001 392.6.5 Filter Slider and Slider for Apertureand Luminous Light Diaphragmsfor the Axio Vert.A1 MAT andAxio Vert.A1 FL Stands− Reflected light filter slider with threepositions for d=25 mm filters (neutral densityand color filters, white balance filter). A two-position filter is available as an option.− Insert and operate the filter slider from theright (Fig. 2-21/1). To this end, remove thecovers from the insertion slot.− Aperture diaphragm slider A, equipped witha setting wheel (Fig. 2-21/2) to open or closethe diaphragm, can be inserted from theright. The FL attenuator may also be insertedhere for fluorescence applications.− The luminous field slider for slot F, equippedwith a setting wheel (Fig. 2-21/3) to open orclose the diaphragm, can be inserted fromthe right.2.6.6 Filter Slider Mounted on the Carrierfor Transmitted Light Illumination− Alternately usable two-position transmittedlight filter slider (Fig. 2-22/2) for d=32 mmfilters (neutral density and conversion filtersor shutter plate) fixed-mounted in the carrier(Fig. 2-22/1)− If an LED illuminator is used, the shutterplate can be inserted into a filter positionand pushed into the light path to block thelight path. Residual light could interfere withfluorescence viewing.When used with transmitted lightLED illumination, the conversion filtercreates the usual daylight impressionduring the microscoping process.Without that filter, the image mayappear slightly bluish on occasion.Do not employ the conversion filterwhen transmitted light HALillumination is installed, as the heatgenerated by the HAL might damagethe filter.Fig. 2-21 Reflected Light Filter Slider andSlider for Aperture and LuminousField DiaphragmsFig. 2-22 Transmitted Light Filter Slider
