Experience superior optical performance with the infinity semi plan microscope designed for professional research and clinical diagnostics. The LW Scientific i4M-BN4A-iSL3 i4 Infinity features premium infinity-corrected optics with Semi-Plan objectives, delivering sharp, high-contrast imaging across the entire field of view. This infinity semi plan microscope provides the superior clarity and resolution traditionally found only on expensive research-grade instruments, making professional-quality imaging accessible to clinical labs, research facilities, and teaching hospitals.
Premium Infinity Semi Plan Microscope Optics
The infinity semi plan microscope utilizes an infinity-corrected optical system, the most advanced platform for microscopy imaging. Infinity optics produce higher resolution and clarity than conventional DIN optical systems. The Semi-Plan objective set (4X, 10X, 40XR, 100XR oil) delivers flat-field imaging across 95% of the field of view, ensuring cells at the edge are as sharp and focused as those in the center.
Each objective features a 30-year anti-fungal coating protecting against environmental damage. Additionally, the infinity semi plan microscope accommodates optional 50X oil objectives for highest-resolution imaging and faster specimen scanning.
Ergonomic Binocular Design for Extended Use
The infinity semi plan microscope features a Seidentopf binocular head inclined 30 degrees and rotating 360 degrees for flexible viewing positions. The interpupillary distance adjusts from 48-75mm to accommodate various users. The rotating head enables taller users to adjust microscope height for ergonomic comfort during extended laboratory sessions.
The 10X/18mm super-widefield eyepieces with built-in diopter adjustment provide expansive specimen visibility. Furthermore, comfortable positioning with flat-resting arm support reduces strain during long observation sessions.
Advanced Specimen Analysis Capabilities
This infinity semi plan microscope provides precise 40X-1000X magnification enabling detailed cell morphology assessment. The mechanical stage (140mm x 130mm) with coaxial drive controls allows smooth, accurate specimen positioning. The moveable 1.25 NA Abbe condenser with iris diaphragm offers professional illumination control essential for clinical diagnostics and research applications.
The variable LED illumination system provides bright, uniform lighting with adjustable intensity. Additionally, the cool LED bulb eliminates heat damage to specimens and offers 25,000+ hours of operation.
Modular Design for Laboratory Versatility
The infinity semi plan microscope features a modular design enabling accessory expansion. Optional digital camera adapters, fluorescence modules, and phase contrast equipment integrate seamlessly. The reverse quadruple nosepiece with ball bearing mounting provides positive click stops ensuring precise objective centering.
The precision-ground mechanical stage with 78mm x 50mm traverse range accommodates diverse specimen sizes. Moreover, the coaxial focusing system with tension control knob and upper limit stop prevents accidental slide damage.
