Description
Broadcast live cellular demonstrations across multi-device science classrooms using the Kern OBE 104T241 Digital Microscope. It features an integrated 5.0 Megapixel 1/2.5″ CMOS camera module with standalone multi-output logic: direct HDMI monitor streaming, local WiFi broadcasting, USB 2.0 PC-linking, and onboard SD card storage for PC-less photo logging. 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, eliminating messy immersion oils completely.
Transmitted light is driven by a high-output 3W LED base module focused through an Abbe 1.25 NA condenser with an adjustable iris diaphragm and filter slot, controlled via a side-mounted rotary dimmer. The 30-degree inclined trinocular head rotates 360 degrees, paired with widefield WF 10x/18 mm eyepieces 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 fine division markings across a 5.5 kg cast-metal frame running on universal 100-240V AC power.
Key Features of Kern OBE 104T241 Digital Microscope
A multi-interface digital trinocular biological compound microscope featuring a pre-mounted 5MP CMOS camera with WiFi, HDMI, and standalone SD card recording. Combines 40x to 400x dry magnification with an Abbe 1.25 NA condenser, 3W LED lighting, and coaxial 2-micron focusing.
- Pre-mounted 5.0 Megapixel 1/2.5″ CMOS sensor with simultaneous WiFi, HDMI, and USB outputs
- Onboard SD card storage slot allows standalone digital still and video capture without a PC
- 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
- Trinocular viewing head inclined at 30 degrees with paired widefield WF 10x/18 mm eyepieces
Multi-Interface T241 Camera & Oil-Free 400x Optics
Eliminating immersion oil cleanup saves valuable instruction time in educational labs and outpatient clinics. The dry 40x objective provides crisp 400x cellular resolution on plant tissues, protozoa, and urinary sediment without sticky residues. The T241 camera head allows instructors to stream live 1080p video directly to an HDMI projector, broadcast over WiFi to student tablets, or save digital homework files directly onto an SD card without needing a laptop.
Abbe Condenser Optics & Coaxial Stage Mechanics
The sub-stage Abbe 1.25 NA condenser lets technicians fine-tune light contrast using the built-in iris diaphragm, bringing out subtle boundaries in unstained wet mounts. The double-layer mechanical stage provides smooth 50 x 30 mm coordinate translation via right-hand drop-down stalks, while the 2-micron fine-focus wheel allows precise focal plane isolation. The spring-loaded 40x objective protects slide cover slips from accidental mechanical strikes during student focusing passes.
- Direct HDMI streaming feeds live video without PC latency, software crashes, or OS lag
- Built-in WiFi hub allows simultaneous multi-user screen sharing across mobile devices
- Dry 40x objective eliminates oil contamination and lens cleanup routines
