Bresser Science TFM-201 Binocular Microscope 40x-1000x

Description

Eliminating edge-of-field optical curvature during pathology rounds, the Bresser Science TFM-201 Binocular Microscope pairs semi-plan optics with precision Kohler illumination. It covers a standard clinical magnification range from 40x to 1000x. The reverse-facing nosepiece holds four Semi-Plan objectives: 4x, 10x, 40x, and 100x oil immersion. Unlike basic achromatic lenses, these semi-plan elements flatten roughly 80% of the image circle, meaning cell walls stay in focus from the center out to the margins of the wide 20 mm field of view.

True Kohler illumination is standard here. A dimmable LED emitter in the base pairs with a height-adjustable Abbe 1.25 NA condenser and an adjustable field diaphragm, letting you focus and center the light cone to wipe out internal glare. The 30-degree inclined binocular head features high-eyepoint WF 10x/20 mm eyepieces with adjustable interpupillary spacing. Built around a dense 6.3 kg (13.9 lbs) metal frame, the stand features a double-layer mechanical stage, adjustable focus tension rings, and an automatic slide lift protection lock to prevent broken glass.

Key Features of Bresser Science TFM-201 Binocular Microscope

A professional clinical laboratory microscope engineered for medical diagnostics, public health screening, and university life science benches. Combines four Semi-Plan objectives with adjustable LED Kohler illumination and an ergonomic 20 mm field of view.

• Semi-Plan objectives (4x, 10x, 40x, 100x oil) deliver flat-field edge sharpness
• Full Kohler illumination with height-adjustable Abbe 1.25 NA condenser and field iris
• Energy-efficient dimmable LED base lamp provides daylight-balanced white light
• Paired high-eyepoint WF 10x/20 mm widefield eyepieces with dioptric adjustment
• Double-layer integrated cross stage with drop-down coaxial XY control stalks
• Coaxial coarse and fine focus drive featuring calibrated tension adjustment rings
• Specimen slide auto-lift protection lock stops accidental objective strikes
• Sturdy 6.3 kg laboratory-grade chassis resists mechanical bench vibration

Semi-Plan Optical Field & True Kohler Glare Suppression

Semi-Plan glass correction minimizes peripheral blur, allowing lab techs to count leukocytes or screen thin bacterial smears without constantly refocusing between center and edge. The integrated Kohler field diaphragm allows precise control over illuminated field diameter. Stopping down the field iris to match your objective’s entrance pupil cuts internal tube reflections, yielding deep contrast on low-contrast unstained cell scrapes.

Tension-Adjustable Focusing & Solid Stage Platform

Focus drag can make or break a long day at the scope. The TFM-201 includes a friction ring on the coaxial focus axle, letting you tighten or loosen knob resistance to suit your hand. The mechanical stage carries two slides at once for rapid side-by-side diagnostic comparisons. The 6.3 kg frame stays solidly anchored, preventing focal drift even when resting heavy hands on the low-position coaxial XY control knobs.

• Kohler condenser alignment eliminates stray light for crisp cellular boundaries
• Focus tension ring lets you dial in custom mechanical resistance without slip
• Reverse-mounted objective turret leaves the stage completely open for slide swaps
