Professional Laboratory Microscope with Plan Optics
Unmatched Optical Clarity
The Laboratory Trinocular Microscope features DIN standard plan objectives—the gold standard in microscopy optics. Unlike standard achromatic objectives that keep only the center 65% of the field in focus, these plan objectives maintain sharp focus across 95% of the entire viewing field. This means you can examine large tissue sections, blood smears, or other specimens without constantly refocusing as you scan across the slide. The high-quality optical system delivers flawless clarity, flatness of field, and accurate color reproduction at all magnification levels from 40x through 1000x.
Designed for Teaching and Documentation
The trinocular head design sets this microscope apart. While you observe specimens through the comfortable binocular eyepieces, the vertical third eyepiece port accommodates a digital camera for capturing images and recording videos. This makes the microscope ideal for teaching situations where you want to demonstrate techniques or share observations in real-time. The captured images and videos are invaluable for documentation, analysis, presentations, and consultations with colleagues. The ergonomic Siedentopf head rotates 360° and includes dual diopters to compensate for differences between your eyes, ensuring comfortable viewing during long observation sessions.
Professional-Grade Components
This microscope incorporates features found in research-grade instruments. The 1.25 N.A. Abbe condenser with iris diaphragm provides exceptional contrast control, while the swing-out filter holder with blue, green, and yellow filters lets you optimize illumination for different specimens. The ball-bearing double-layer mechanical stage with low-position coaxial controls allows precise slide positioning with fingertip accuracy. The coaxial fine and coarse focusing system includes tension adjustment to eliminate stage drift—critical when working at high magnifications. Premium 20-watt halogen lighting with variable intensity ensures bright, even illumination that's suitable for all observation techniques.
Built for Demanding Applications
With magnifications up to 1000x using the oil immersion objective, this microscope excels in biology, medical, and veterinary laboratory applications. The 100x oil immersion objective lets you examine bacteria, blood cells, tissue samples, and other minute specimens with exceptional resolution. The cast aluminum frame with chemical-resistant coating provides the stability and durability required in professional settings. All components are designed to work together seamlessly—the plan objectives are parcentered and parfocaled, meaning they stay in alignment and nearly in focus when you switch magnifications, allowing you to work efficiently without constant readjustment.
Frequently Asked Questions
- What is the advantage of plan optics over standard objectives? Plan optics provide a flat field of view with 95% of the image in sharp focus simultaneously, compared to standard achromatic objectives that keep only the center 65% focused. This flat-field correction eliminates the need to constantly refocus when scanning across a specimen, making observation more efficient and ensuring accurate photomicrography. Plan objectives use additional lens elements to correct for field curvature, delivering edge-to-edge clarity that's essential for examining large tissue sections, blood smears, and other specimens.
- How does a trinocular microscope work for image capture? A trinocular microscope has three eyepiece positions: two for direct binocular viewing and a third vertical port for attaching a digital camera. Light from the specimen is split by a prism assembly, directing it either to the binocular eyepieces for observation or to the camera port for image capture. This allows you to view and photograph specimens simultaneously, making it ideal for documentation, teaching demonstrations, and creating presentations without interrupting your observation workflow.
- When should I use the 1000x magnification with oil immersion? Use 1000x magnification with the oil immersion objective when examining very small specimens like bacteria, blood cells, chromosomes in dividing cells, or subcellular structures. Oil immersion is essential at this magnification because it prevents light scattering between the slide and objective lens. The immersion oil has a refractive index similar to glass, allowing more light to reach the objective and dramatically increasing resolution. Without oil immersion, magnifications above 400x would produce blurry, low-resolution images due to light loss.
- What applications is this laboratory trinocular microscope best suited for? This microscope is designed for professional biology, medical, and veterinary laboratory work where high-quality imaging and documentation are essential. It excels in examining stained tissue sections, blood smears, microorganisms, parasitology samples, and cytology specimens. The trinocular head makes it particularly valuable in teaching environments, clinical settings where image sharing is important, and research applications requiring detailed photomicrography. The plan optics and 1000x capability make it suitable for any application requiring accurate observation of fine specimen details.
