Product Title
B-290TB Digital Binocular Brightfield Microscope 1000x with 3.1 MP Camera & Tablet
Long Description
The B-290TB Digital Binocular Brightfield Microscope is a high-performance laboratory microscope designed for educational, clinical, research, and industrial applications. Equipped with advanced N-PLAN objectives, a built-in 3.1 MP CMOS camera, and a 10.1” IPS multi-touch tablet, this microscope delivers exceptional image clarity and digital imaging capabilities for professional laboratory work.
The microscope features a robust aluminum die-cast construction with ergonomic binocular observation head inclined at 30° and fully rotatable 360° design for comfortable long-term use. Its high-quality optical system provides standard magnifications from 40x to 1000x with superior image contrast and resolution.
The integrated X-LED3 illumination system provides bright, energy-efficient daylight illumination with a lifespan exceeding 65,000 hours. The rackless mechanical stage ensures smooth slide movement and precise specimen positioning for accurate observations.
The built-in 3.1 MP CMOS camera allows digital image capture and live viewing directly through the supplied Windows 11 tablet. The included PROVIEW software enables image analysis, documentation, and laboratory reporting.
Ideal for brightfield microscopy, the B-290TB also supports optional darkfield and simple polarized light observation methods, making it a versatile solution for laboratories, universities, hospitals, pathology labs, and research centers.
