Key Benefits

Infinity plan objectives deliver flat, high-contrast images across the field at all magnifications
Seidentopf binocular or trinocular head with 30° inclination and 360° rotation for ergonomic viewing and camera integration
Coaxial coarse and fine focusing knobs allow smooth, precise focus adjustment without changing hand position
Mechanical stage with 78mmx55mm travel enables accurate sample positioning and repeated inspection
Koehler illumination with adjustable field diaphragm and iris diaphragm ensures even, glare-free lighting
Wide voltage input (100V~240V) allows use in labs with varying power supplies
Optional fluorescence, phase contrast, dark field, and polarizing attachments expand the instrument's analytical capabilities

Application Scenarios

Routine histology and cytology slide examination in clinical or research laboratories
Teaching undergraduate biology with consistent image quality across multiple students
Quality control inspection of cell cultures, tissue sections, and microorganisms
Microscopy work requiring precise focus and stage movement, such as in parasitology or microbiology
Research applications needing fluorescence, phase contrast, or polarized light for specimen differentiation

Who It Is For

Clinical and veterinary laboratories performing routine sample analysis
University and school teaching labs requiring durable, multi-purpose microscopes
Research labs in biology, microbiology, and cell science
Quality control departments in pharmaceutical and biotech manufacturing
Medical and biological research institutions conducting advanced microscopy

Problems It Solves

Fixed focus or non-coaxial knobs make precise focusing difficult during extended use
Non-infinity optical systems produce image distortion at the edges, especially at higher magnifications
Lack of mechanical stage forces manual sample movement, increasing risk of misalignment
Poor illumination leads to glare or uneven lighting, reducing image clarity
No option for digital imaging or camera attachment limits documentation and sharing
Inability to switch between fluorescence, phase contrast, or polarized light requires multiple instruments

Technical Features

Infinity plan optical system ensures flat, high-resolution imaging across the entire field
Seidentopf binocular or trinocular head with 30° inclination and 360° rotation for operator comfort and camera setup

Quintuple nosepiece allows quick objective switching without removing the nosepiece
Mechanical stage with 78mmx55mm travel enables precise, repeatable sample positioning
Coaxial coarse and fine focusing knobs provide smooth, synchronized focus control
Swing-out Abbe condenser with N.A. 1.25 and iris diaphragm supports high-resolution imaging
Koehler illumination with adjustable field diaphragm and iris diaphragm for optimal light control
Wide voltage input (100V~240V) ensures compatibility with global power standards
6V/20W halogen lamp provides stable, bright illumination for routine work
Optional 6V/30W halogen lamp or 3W-LED illumination for extended use or lower heat

Comparison With Other Options

XAB301 Laboratory Biological Microscope	The XAB300 includes a trinocular head and optional fluorescence, phase contrast, and polarizing attachments; the XAB301 is a basic binocular model without these advanced options.
XAB302 Laboratory Biological Microscope	The XAB302 is a trinocular model with a 100W mercury lamp fluorescence unit; the XAB300 offers both mercury and LED fluorescence options, giving more flexibility in light source choice.
Standard biological microscope without mechanical stage	The XAB300's mechanical stage allows precise, repeatable movement; a model without it requires manual handling, increasing error risk during inspection

Use Guide

Adjust the interpupillary distance to 48-75mm before focusing to ensure a single merged image
Start with the lowest magnification objective to locate the specimen, then switch to higher magnifications
Use the Abbe condenser and iris diaphragm to optimize contrast and resolution for each objective
For fluorescence work, ensure the correct filter is in place and the lamp is properly aligned
When using digital cameras, connect via the 1x or 0.57x C-mount adapter and confirm focus adjustment
Keep the halogen lamp clean and avoid touching the bulb with bare hands to prevent premature failure
