Hund AFL Plan 50 Fluorescence Binocular Research Gear

Description

Screen for tuberculosis and evaluate routine diagnostic fluorophores with the Hund H600 AFL Plan 50 Microscope epifluorescence clinical system. It runs an infinity-corrected optical train delivering 100x, 400x, and 1000x magnification. The objective nosepiece carries three specialized Plan Achromatic lenses: 10x/0.25, 40x/0.65, and 100x/1.25 oil-immersion. Unlike massive research rigs, this unit uses a compact 50W HBO mercury vapor burner inside the rear epi-tower, powered by an external stabilizing ballast to keep excitation arcs steady during slide screening.

For standard brightfield histology, the base houses an adjustable 6V 30W halogen lamp beneath an Abbe 1.25 NA condenser. Switching over to fluorescence takes seconds: slide the filter block into the optical path to engage dedicated Blue or Green excitation cubes. The reverse-facing 4-position nosepiece keeps the front of the stage clear, while the 160 x 140 mm double-layer mechanical stage provides 76 x 50 mm of low-slung coaxial XY translation. The binocular head is angled at 30 degrees, rotating 360 degrees with high-eyepoint WF 10x/20 mm eyepieces. Net system weight is 11.2 kg.

Key Features of Hund H600 AFL Plan 50 Microscope

A routine clinical epifluorescence microscope designed for pathology and mycobacterium screening. Pairs infinity Plan Achromatic optics with a 50W HBO mercury burner tower and sub-stage halogen brightfield illumination.

• Plan Achromatic infinity objectives: 10x, 40x, and 100x oil immersion
• 50W HBO mercury burner capsule paired with an external stabilizing ballast console
• Dual-position excitation slider block loaded with Blue and Green filter sets
• Sub-stage 6V 30W halogen lamp with 1.25 NA Abbe condenser and iris diaphragm
• Double-layer mechanical stage (160 x 140 mm) with low-profile coaxial XY drive
• Precision coaxial focus drive graduated to 2-micron fine increments
• 30-degree inclined binocular head with high-eyepoint WF 10x/20 mm eyepieces
• Heavy cast-metal frame weighing 11.2 kg to eliminate bench vibration

Infinity Optical Correction & Routine Epifluorescence

The anti-fungus treated Plan Achromatic objectives eliminate optical curvature, providing flat focus right to the perimeter of the 20 mm field of view. The 50W mercury arc produces crisp fluorescence excitation on acridine orange and auramine-O smears without generating the excessive heat of larger 100W systems. The external ballast console smooths line-voltage spikes to prevent flickering while you log positive diagnostic fields.

Ergonomic Stage Mechanics & Dual-Illumination Control

Having coaxial focus knobs located low on the chassis means technicians can rest their forearms flat on the bench, reducing shoulder fatigue during high-volume screening days. The fine-focus knob moves in 2-micron divisions, making it easy to isolate thin focal planes at 1000x oil immersion. The reverse-angle objective turret tilts lenses back toward the stand neck, preventing accidental finger contact when dropping new glass slides onto the stage clips.

• Reverse-facing turret protects front objective lenses during slide loading
• Dual-input power layout runs halogen on internal circuitry and mercury on ballast
• Abbe condenser iris diaphragm dials in optimal numerical aperture for brightfield
