NOSEPIECE
Revolving sextuple reversed nosepiece on ball-bearings with 26 mm objectives mounting threads
INFINITY OPTICAL SYSTEM (IOS)
The infinity optical system (OIS) of the Delphi-X Observer™ consists of Super wide field SFWF 10x/25 mm eyepieces, high numerical aperture 45 mm parafocal objectives and a 200 mm focal length tube lens. The 200 mm focal length tube lens reduces the angle of the light rays passing through the optics and as a direct result improving significantly 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
OBJECTIVES
The Delphi-X Observer™ is standardly supplied with Plan Semi-Apochromatic BD 5x/0.15 WD 20 mm, 10x/0.30 WD 11 mm and 20x/0.45 WD 3.1 mm Plan Apochromatic BD 50x/0.80 WD 1 mm, 100x/0.90 WD 1 mm objectives infinity corrected brightfield/darkfield objectives

STAGE
- Large 215 x 170 mm stage with 105 x 105 mm integrated right-handed mechanical stage
- Stage height can be changed to sample size or can be lowered by one inch for user ergonomics using the optional nose piece lowering attachment (DX.9887)
- The stage can be mounted in two positions:
Nosepiece lowering attachment
The nosepiece lowering attachment lowers the height of the revolver with 40 mm which allows the stage to be used in the 40mm lower position as well (DX.9887)
Eye-level riser
The eye-level riser can raise the eye-point height by 25,4 mm at one time (DX.9885)
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
LONG W.D. CONDENSER
In height adjustable long working distance N.A. 0.65 condenser (10.2 mm) with numerical aperture identification marks allows easy setting
ILLUMINATION
The Delphi-X Observer materials science microscope 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 attenuation of the light intensity for all kinds of samples and one Light Balancing Daylight filter filter (LBD)
The microscope comes standard with a analyzer and a polarizer which can easily be inserted into the free slots into the Epi-Illuminator for high quality polarized images. Further a rotating cassette is implemented for quick changing between darkfield, brightfield and dimmed brightfield
NOMARSKI DIC (optional)
With the redesign of the DIC-module visualization of height differences which normally cannot be displayed using brightfield techniques has greatly improved. These relief like images are ideal for surface inspections of wafers, LCD screens etc
