AmScope T690 Series Trinocular Compound Microscope up to 2500X Köhler Illumination Plan Optics

AmScope T690 Series Trinocular Microscopes with Infinity Optics and Professional Magnification

Designed for laboratories and universities, T690 models deliver high-precision imaging with up to 2500X magnification and Köhler illumination system.

The AmScope T690 Series is designed for professional biological applications. Its infinity-corrected optical system reduces distortion and improves color accuracy. The plan-achromatic lenses ensure edge-to-edge sharpness, while the Köhler halogen illumination provides even lighting, reducing eye strain even during long observation sessions. Featuring an adjustable trinocular head and top photo port, it's ideal for documentation using optional cameras. Its ergonomic frame, double-layer mechanical stage, and coaxial focus system support a smooth and precise workflow.

Key Features:

• Infinity-corrected optics: enhances color accuracy and minimizes distortion.
• Plan-achromatic lenses: sharp, flat-field imaging with color fidelity.
• Köhler halogen illumination: even, adjustable light for high contrast.
• Trinocular head with photo port: enables camera mounting for capture and monitoring.
• Double-layer mechanical stage: precise and convenient sample navigation.
• Ergonomic design: easily accessible focus and movement controls for efficient operation.
• Immersion oil compatible: for high-resolution observations with 100X objectives.
• Durable construction: built for demanding lab environments.
