Description
The Kern OBE 104C832 USB3 Digital Microscope delivers rapid-frame-rate digital histology screening without oil-immersion mess. Powered by a finite 160 mm optical system, it delivers 40x, 100x, and 400x magnification via three dry achromatic objectives: 4x/0.10, 10x/0.25, and spring-loaded 40x/0.65. A factory-calibrated 5.0 Megapixel 1/2.5″ CMOS camera module is built onto the vertical photo port, streaming uncompressed live video and digital measurements over high-bandwidth USB 3.0 directly to lab PCs with zero motion lag.
Transmitted illumination is supplied by an energy-efficient 3W LED base lamp focused through a height-adjustable Abbe 1.25 NA condenser equipped with an iris diaphragm and filter slot. The 30-degree inclined trinocular head features paired widefield WF 10x/18 mm eyepieces with left-tube diopter adjustment across a 50 mm to 75 mm interpupillary span. The 125 x 115 mm mechanical stage provides 50 x 30 mm of drop-down coaxial XY translation, while coaxial coarse and fine focus knobs feature 2-micron graduations across a 5.2 kg frame operating on universal 100-240V AC power while the camera draws USB bus power.
Key Features of Kern OBE 104C832 USB3 Digital Microscope
An integrated digital trinocular biological compound microscope featuring a pre-mounted 5MP USB 3.0 camera. Combines 40x to 400x dry magnification with rapid frame-rate video streaming, an Abbe 1.25 NA condenser, and a double-layer mechanical stage.
- Pre-mounted 5.0 Megapixel 1/2.5″ CMOS camera module with high-speed USB 3.0 data transfer
- Uncompressed high-frame-rate video streaming eliminates display lag during live slide scanning
- Dry achromatic objectives: 4x, 10x, and spring-loaded 40x (no immersion oil required)
- High-output transmitted 3W LED illumination with continuous electronic rotary dimmer
- Double-layer 125 x 115 mm mechanical stage with 50 x 30 mm coaxial XY travel controls
- Coaxial coarse and fine focus drive with calibrated 2-micrometer fine division markings
- Height-adjustable Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm
- Solid 5.2 kg cast-metal chassis provides complete vibration-free benchtop stability
High-Speed USB 3.0 Throughput & Dry 400x Optics
Standard USB 2.0 cameras often drop frames or show noticeable latency when panning across cellular smears. USB 3.0 solves that problem by transmitting raw, uncompressed 5MP video frames instantly, giving operators a smooth, real-time live feed that matches hand movements on the stage. Achromatic multi-coated lenses preserve flat-field edge resolution and true color saturation across stained tissue margins, while the dry 40x objective provides high-power cellular clarity without messy oils.
Coaxial 2-Micron Focus Mechanics & Stage Control
The coaxial fine-focus wheel moves in calibrated 2-micron increments, letting technicians isolate thin focal slices through cell scrapings without overshooting. The double-layer mechanical stage holds slides firmly, gliding smoothly across 50 x 30 mm via drop-down right-hand stalks, keeping hand movements relaxed during long diagnostic shifts. The sub-stage 3W LED module produces cool, daylight-balanced white light that renders histological stains with authentic color saturation.
- USB 3.0 interface ensures real-time, stutter-free video during active diagnostic slide navigation
- Pre-mounted camera pod maintains factory optical alignment over the vertical photo channel
- Dry 40x objective eliminates oil contamination and lens cleanup routines
