Delphi-X Observer Fluorescence Series

Overview

State-of-the-art microscopes for advanced Life Science fluorescence applications. The outstanding optical performance of the Delphi-X Observer makes it ideal for Life Science fluorescence applications where a high performance optical system is required. The 22 mm fields of view of the Super wide field eyepieces and the high numerical aperture of the Plan Fluarex 60 mm parafocal EIS objectives enable perfect observations and color rendering at high resolving power.

Specifications

EYEPIECES

Standard super wide field SWF 10x/22 mm, Ø 30 mm tubes.

STANDARD HEAD

Siedentopf trinocular head with 30° inclined tubes. Interpupillary distance adjustable between 47 and 78 mm. Three position beamsplitter (0:100/ 80:20 / 100:0). Diopter ± 5 adjustments on both eyepieces.

ERGONOMIC TILTING HEAD

Optional ergonomic 0 to 35° tilting trinocular head supplied with SWF 10x/22 mm eyepieces, interpupillary distance 47-78 mm and photo tube with standard Ø 23.2 mm tube.

NOSEPIECE

Revolving sextuple reversed nosepiece on ball-bearings.

ENHANCED INFINITY SYSTEM (EIS)

The enhanced infinity system (EIS) of the Delphi-X Observer™ consists of Super wide field SFWF 10x22 mm eyepieces, high numerical aperture 60 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 of the images produced. The objectives have a larger diameter enabling a much higher numerical aperture, thus 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.

PLAN ACHROMATIC EIS OBJECTIVES (clinical routine applications)

The Delphi-X Observer™ is standard supplied with Plan Achromatic 4x/0.10, 10x/0.25, 20x/0.40, S40x/0.65 and S100x/1.25 (oil immersion) infinity corrected EIS objectives.

Available as an option: 2x/0.06, S50x/0.95 (oil immersion) and S60x/0.80.

PLAN SEMI-APOCHROMATIC FLUAREX OBJECTIVES (anatomo- and histopathology applications)

The Delphi-X Observer™ can also be supplied with Plan Semi-Apochromatic 4x/0.13, 10x/0.30, 20x/0.50, S40x/0.75 and S100x/1.30 (oil immersion) infinity corrected EIS objectives.

STAGE

190 x 152 mm stage with 80 x 54 mm integrated right-handed mechanical stage. Designed for 2 slides. Standard supplied with scratch-resistant Gorilla glass. Sapphire scratch-resistant glass is available on request. Left-handed mechanical stage is available on request.

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.

CONDENSER FOR BRIGHTFIELD

In height adjustable N.A. 0.90/1.25 Abbe swing-out condenser with numerical aperture identification marks.

100 W HBO ILLUMINATION FOR FLUORESCENCE

The Delphi-X Observer can be configured with a rotating carousel which can contain up to six filter cubes and supplied with a 100 W HBO mercury vapor light source for a broad powerful light spectrum.

Supplied with standard fluorescence filters sets for Blue excitation (EX460-490 DM500 EM520LP) and Green excitation (EX510-550 DM570 EM575LP), UV shield and external power supply.

Other more specific and optimized application-related fluorescence filter sets are also available.

LED ILLUMINATION FOR FLUORESCENCE

The Delphi-X Observer can also be configured with two different LED systems for fluorescence:

• LE.6400 LED source with 365, 470, 525 and 630 nm LED's with the standard 6-positions attachment and the 2 standard filter sets AE.9746 (Green) and AE.9745 (Blue excitation)
• Integrated 4-positions LED attachment (DX.9200-LED) supplied with three 365, 485 and 525 nm LED's and three standard filter sets AE.9748 (UV), AE.9746 (Green) and AE.9745 (Blue excitation)

STANDARD GENERAL PURPOSE FLUORESCENCE FILTER SETS

Supplied with standard fluorescence filter sets for blue excitation (EX460-495 DM505 EM510LP) and green excitation (EX510-550 DM570 EM575LP), UV shield and external power supply. Optional: fluorescence filter sets for UV excitation (EX330-385 DM400 EM420LP) and violet excitation (EX400-410 DM455 EM460LP). On special request, the microscope can also be supplied with optimized, and zero-pixel shift optimized filter sets.

DIASCOPIC ILLUMINATIONS

Two Köhler illuminations are available for the Delphi-X Observer™ microscope:

• Diascopic intensity adjustable 3 W NeoLED™ Köhler illumination with internal 100-240 V power supply
• Diascopic intensity adjustable 100 W halogen Köhler illumination with internal 100-240 V power supply

The diascopic halogen illumination comes with 2 push-in/push-out neutral density filters for smooth attenuation of the light intensity for all kind of samples. The diascopic NeoLED™ illumination comes with one frosted diffuse filter.

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 & holder makes sure the right tool is always available.

STORAGE
