STANDARD HEAD

Siedentopf trinocular with 30° inclined tubes. Interpupillary distance adjustable between 47 and 78 mm. The trinocular standard head has an optical path selector (100:0 / 80:20 / 0:100). Diopter adjustment on both eyepieces

ERGONOMIC TILTING HEAD
Optional ergonomic 0 to 35° tilting trinocular head supplied with SWF 10x/25 mm eyepieces, interpupillary distance between 47-78 mm and photo tube with a standard Ø 23.2 mm tube. The trinocular tilting head has an optical path selector (100:0 / 80:20 / 0:100). Diopter ± 5 adjustments on both eyepieces

NOSEPIECE
Revolving quintuple reversed nosepiece on ball-bearings with centering screws for objectives 

OBJECTIVES 
The following infinity corrected EIS objectives are supplied with or available for the Delphi-X Observer™: 

¹⁾ Optional 
²⁾ For models for polarization applications with incident illumination. No cover glass correction
³⁾ For models for polarization applications without incident illumination. With 0.17 mm cover glass correction. All objectives are 45 mm parfocal and have a M25 x 0.7 mounting thread. All optics are anti-fungus treated and anti-reflection coated for maximum light throughput

ENHANCED INFINITY SYSTEM (EIS)
The enhanced infinity system (EIS) of the Delphi-X Observer™ consists of super wide field SFWF 10x25 mm eyepieces, high numerical aperture 45 mm parfocal objectives. This tube lens reduces the angle of the light rays passing through the optics and as a direct result significantly improves the chromatic aberration corrections and contrast. The objectives with larger diameter enable much higher numerical apertures improving the overall resolving power of the optical system

For all these reasons the Delphi-X Observer™ offers superior optical performance for the most demanding applications

STAGE
Diameter 190 mm circular stage. 360° Rotatable with Vernier and two object clamps and an optional 30 x 30 mm X-Y mechanical stage

CONDENSER 
Height adjustable Abbe N.A. 1.25 condenser with iris diaphragm and 306° rotatable polarizer 

FOCUSING
Coaxial coarse and fine adjustment, 100 graduations, 1 µm precision, 100 μm per rotation, total travel range is approximately 35 mm. Supplied with an adjustable rack stop to prevent damage to sample and objectives. The coarse adjustments are equipped with friction control. The focusing knobs can be switched from left to right according to the user’s preference

ILLUMINATION
The Delphi-X Observer materials science microscope for polarization applications is equipped with epi and diascopic intensity adjustable 100 W halogen illumination with internal 100-240 Vac power supply. The diascopic halogen illumination comes with two push-in/push-out neutral density filters for smooth attenuation of the light intensity for all kinds of samples

POLARIZATION 
Supplied with 360° rotatable polarization filter, analyzer, Bertrand lens, 1 λ first red plate, 1/4 λ retardation plate, a quartz wedge

REFLECTED ILLUMINATION ATTACHMENT 
Up to six observation modules can be placed in the rotating structure. Comes with brightfield and brightfield with ND filter positions

ICARE SENSOR
The unique iCare Sensor is developed to avoid unnecessary loss of energy. The illumination of the microscope automatically switches off shortly after microscopists step away from their position

CARRYING GRIP
The carrying grip at the back of the microscope ensures safe transportation of the microscope and the integrated tool and holder make sure the right tool is always available

STORAGE

EAE-9914-D

PACKAGE CONTENT
Supplied with power cord, dust cover, a spare fuse, user manual and universal tool. All packed in a polystyrene box
