Binocular Biological Microscope | Plan Objectives 4x–100x | WF10x/20mm | 145×140mm Stage

A plan objective is an advanced lens that corrects optical spherical aberration, producing a completely flat field of view. This means the specimen remains in sharp focus from the very center all the way to the absolute edges.

Achromatic objectives are color-corrected but may leave the outer 30-40% of the field slightly out of focus due to lens curvature. Plan objectives correct this curvature entirely, resulting in a 100% flat, in-focus image, which is crucial for detailed medical and research work.

While both provide a flat field of view, an infinity plan system projects light as parallel beams between the objective and the tube lens. This allows you to add optical accessories (like phase contrast rings or polarizers) into the light path without distorting the image or altering the magnification.

A Seidentopf head allows users to adjust the interpupillary distance (the distance between the eyes) by folding the eyepieces up or down without altering the focus length, ensuring a comfortable experience for different users.

It offers a laboratory biological microscope 40x to 1000x magnification with plan objectives range, combining the WF10x/20mm eyepieces with the 4x, 10x, 40x, and 100x oil immersion objectives.

WF10x means it provides 10x magnification with a "Wide Field" of view. A 20mm field is larger than standard 18mm ones, and a high eyepoint design allows users to comfortably view the entire field even while wearing eyeglasses.

The Abbe condenser NA 1.25 focuses and concentrates the LED light directly onto the specimen. NA 1.25 is ideal for achieving maximum resolution with high-power (100x oil) objectives.

It features a highly robust 145x140mm double slide holder mechanical stage with a generous travel range of 76x52mm, perfect for high-throughput laboratory analysis.

No, the binocular head is fixed for visual observation only. If you need camera capabilities, we recommend our GBS.12.2601-AT Trinocular model.

These are standard in hospitals, clinical pathology labs, blood testing centers, and advanced university microbiology departments where digital documentation is not required but excellent optical clarity is.

Plan objectives provide a perfectly flat field of view. When looking at a blood smear or tissue sample, the entire image is sharp simultaneously, reducing eye strain and improving diagnostic accuracy.

It means the coarse and fine focus knobs are mounted on the same axis (one inside the other). This allows for quick, intuitive focus adjustments without having to move your hands to different parts of the microscope.

Specialized synthetic microscope immersion oil is used. It matches the refractive index of the glass objective, preventing light from scattering and drastically improving image resolution at 1000x magnification.

The plan biological microscope with interpupillary distance 48 to 75mm allows users to adjust the width between the eyepieces to precisely match their own eyes for comfortable viewing.
