Binocular Laboratory Microscope | Infinity Plan HC | 216x150mm Stage | LED Kohler

Infinity Plan HC (High Contrast) objectives provide a completely flat, edge-to-edge field of view while simultaneously correcting for chromatic aberration using parallel (infinity) light rays. They produce incredibly sharp, distortion-free images required in high-level clinical diagnostics and research.

Standard achromatic objectives focus the center of the image well, but the edges can appear blurry. Infinity Plan HC objectives eliminate this edge blur (creating a "Plan" or flat field) and utilize an infinity-corrected optical path, allowing for higher contrast and the addition of optical accessories without degrading image quality.

Infinity optical systems allow you to insert auxiliary components (like phase contrast rings, polarizers, dark field sliders, or beamsplitters) into the optical path between the objective and the tube lens without changing the magnification or degrading the image focus.

A massive 216x150mm double-layer mechanical stage provides superior stability and allows for a larger moving range (75x55mm). It easily accommodates a double slide holder for rapid multi-specimen observation without constantly switching slides, making clinical workflows much faster.

A graphite-coated stage is highly resistant to scratches, harsh laboratory chemicals, and wear over time. It ensures that slides glide smoothly across the surface without snagging, extending the lifespan of the microscope's mechanics.

A Seidentopf head lets you adjust the interpupillary distance (the distance between your eyes, from 48 to 75mm) by rotating the optical tubes up or down on an axis. Crucially, doing this does not alter the microscope's focal length, keeping your sample in perfect focus.

With an older "sliding" binocular head, you pull the eyepieces straight apart to adjust for eye distance, which changes the tube length and forces you to refocus the microscope. A Seidentopf head rotates, maintaining the exact same tube length and focus.

WF stands for Wide Field. It magnifies the image 10 times and provides a 22mm field of view. A 22mm FOV is considered "extra-wide" and allows you to see significantly more of the specimen at once compared to standard 18mm eyepieces.

The Abbe condenser gathers and concentrates the light from the LED source onto the specimen. An NA (Numerical Aperture) of 1.25 matches the high NA of a 100x oil immersion objective, ensuring maximum resolution and image brightness at 1000x magnification.

Kohler illumination is a specialized optical alignment that provides incredibly even, bright, and perfectly focused light across the entire specimen field. Combined with 3W LED technology, it provides crisp, heat-free imaging for high-magnification work without damaging live cells.

Coaxial means the coarse and fine adjustment knobs are aligned on the same axis for intuitive use. This model features an ultra-precise 0.001mm fine division, allowing for microscopic adjustments to focus, essential when viewing details at extreme magnifications.

The GBS.12.1502-B Infinity Plan model is highly modular and ready for phase contrast, dark field, polarization, and even fluorescence attachment upgrades as your laboratory's needs expand.

These microscopes are heavily utilized in advanced university research labs, clinical diagnostic centers, pharmaceutical testing facilities, pathology departments, and biotechnology institutes across India.

The laboratory microscope 216x150mm stage price India depends on the specific optics and optional attachments you select. Please request a quote using our contact form for the best B2B pricing and PAN India delivery options.

A binocular microscope has two eyepieces for direct, ergonomic viewing. A trinocular microscope has the same two eyepieces, plus a third vertical viewing tube specifically designed to mount a digital microscope camera.

Yes, one of the main advantages of the GBS.12.1502 series is modularity. If you purchase the binocular version now, you can later purchase an optional C-mount trinocular head upgrade to swap out the head and attach a camera.
