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.

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 360° 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.
