Technical Specifications

The MBL4000-T-LED-SET is a complete photo and video microscopy kit from A.KRÜSS Optronic. It bundles the MBL4000-T-LED trinocular compound microscope, the MKTV8 microscope camera, and the MKTV Full HD display into one matched package, so the camera, display, and optics arrive together rather than as three separate orders. The microscope carries five infinity-corrected plan-achromatic objectives from 4X to 100X, a Siedentopf trinocular head, and 5W LED Köhler illumination. The specifications below cover the complete set as shipped.

Pre-installation Requirement:
Place the microscope on a rigid, level bench with clearance above for the trinocular head and camera, and enough depth for the stage travel. Connect the external mains adaptor to a grounded supply within 100–240 VAC. Connect the camera to the display by HDMI, and to a PC by USB 3.0 or WLAN if PC capture is needed. Allow the LED illumination to stabilise before critical imaging. Confirm the camera is seated correctly in the C-mount before the first capture.

Why This Kit Removes the Guesswork From Photo Microscopy

Buying a microscope, a camera, and a display separately means three compatibility questions, three delivery schedules, and three manuals written for three different products. The MBL4000-T-LED-SET trinocular microscope kit closes that gap by shipping the three matched components as one package. The camera fits the C-mount, the display connects to the camera by HDMI, and the optics are chosen for the camera sensor.

The bundle does not cut the microscope short. The MBL4000-T-LED carries five plan-achromatic infinity-corrected objectives from 4X to 100X, a 360° rotatable Siedentopf trinocular head, an ABBE condenser with Köhler centering, and a mechanical stage with 0.1 mm graduations. The beam splitter switches between 100% eyepiece view and 20/80 eyepiece/camera view, so you can look through the eyepieces and capture to the display in the same session.

For buyers sourcing through OS4U, the configuration questions are whether dark-field illumination belongs in your workflow, whether the MK12 camera is a better fit than the included MKTV8, and whether prepared slides should be added to the order. The KRÜSS MBL4000-T-LED-SET page lists the current set contents.

Key Benefits

Three matched components, one order

The MBL4000-T-LED-SET trinocular microscope kit ships the microscope, camera, and display together, with the cables and adaptors needed to connect them. The camera is seated in the C-mount, the display connects by HDMI, and the components are matched before they reach your bench.

Magnification from 4X to 1000X

Five infinity-corrected plan-achromatic objectives from 4X to 100X, paired with 10X wide-field eyepieces, reach up to 1000X. The 100X oil objective with NA 1.25 covers high-resolution work, and the 20X and 40X spring-loaded objectives protect the lens if the stage is raised too far.

Köhler illumination with LED stability

5W LED Köhler illumination with field diaphragm, brightness control, and a colour filter recess. The LED gives consistent colour temperature and long service life, and Köhler centering keeps the illumination even across the field.

Camera and display without a PC in the loop

The MKTV8 camera captures 8 MP images at 3840 x 2160 and sends live view to the 11.8-inch Full HD display over HDMI. For shared viewing during training or group review, that is the practical setup. For capture to a PC, USB 3.0 and WLAN are both available.

Stage control with real measurement

The mechanical stage measures 182 x 140 mm with 0.1 mm graduations and 77 x 52 mm travel. Combined with the 2 μm fine-focus accuracy, the stage supports measurement and repeatable positioning rather than approximate scanning.

One platform for brightfield and darkfield

The ABBE condenser handles brightfield with Köhler centering. A dark-field condenser is available as an option, so the same microscope extends to unstained and low-contrast samples without a second instrument.

Solving the Problems That Slow Microscopy Down

Struggling with camera and microscope compatibility? The kit ships matched components with the camera seated in the C-mount and the display connected by HDMI. No compatibility research, no adapter hunting.

Losing time switching between eyepiece viewing and camera capture? The beam splitter switches between 100% eyepiece view and 20/80 eyepiece/camera view. Both modes are available without removing the camera.

Getting uneven illumination across the field? Köhler illumination with a centered ABBE condenser, field diaphragm, and brightness control keeps the field even. The LED source holds consistent colour temperature.

Needing high magnification for fine detail? The 100X oil objective with NA 1.25 reaches up to 1000X total magnification. The 20X and 40X spring-loaded objectives protect against stage contact.

Running training or group review sessions? The 11.8-inch Full HD display shows live view to a room without each person crowding an eyepiece. The same setup supports image and video recording to the included SD card.

Worried about sample contrast? Brightfield with Köhler illumination covers stained samples. A dark-field condenser option extends the microscope to unstained and low-contrast specimens.
