The Globe Scientific iScope Binocular Brightfield Microscope (EIS-1152-PLI) delivers full flat-field Plan PLI 4/10/S40/S100x oil IOS objectives on the iScope platform in a binocular configuration. Without a trinocular camera port, 100% of the collected light reaches the eyepieces for the brightest possible visual observation. This is the best-value iScope for workstations dedicated to visual microscopy where digital imaging is not required. Binocular PLI: Maximum Light at a Lower Price The binocular head directs all available light to the eyepieces — trinocular heads split a portion to the camera port even when no camera is attached, slightly reducing eyepiece brightness. This makes the binocular model ideal for student stations, clinical workstations where visual reading is the primary task, and high-volume slide review where eyepiece brightness reduces fatigue during long sessions. The cost savings over the trinocular EIS-1153-PLI can be significant when equipping multiple workstations. Plan Objectives for Clinical-Grade Imaging The Plan PLI objectives correct field curvature across 100% of the visible area. Every cell, every structure, every staining detail is sharp from center to edge. This is the mid-tier objective in the iScope lineup — above the E-Plan EPLI (corrected across ~80%) and below the phase contrast PLPHI tier. For a lab that works exclusively with stained slides and does not need phase contrast, PLI objectives provide the ideal balance of optical quality and cost. Optical Configuration Eyepieces: EWF 10x/22mm (22mm field of view) Objectives: Plan PLI 4x/10x/S40x/S100x oil IOS Stage: Rackless with ergonomic low-position controls Illumination: 3W NeoLED Koehler Head: Binocular with height-adjustable eye tubes Applications Student workstations in histology and microbiology teaching labs, clinical brightfield slide review (H&E, Gram stains, Wright-Giemsa smears), high-volume slide screening where eyepiece brightness reduces eye fatigue, veterinary clinical practice, and any brightfield microscopy application where digital imaging is handled by a separate station or not required. The Multi-Station Math: Why Binocular Saves Significant Budget The price difference between the binocular EIS-1152-PLI and the trinocular EIS-1153-PLI multiplies across a fleet. In a 20-station teaching lab, choosing binocular for all student stations and placing one trinocular at the instructor desk (with a camera) can save hundreds to thousands of dollars versus making every station trinocular. Students at binocular stations get the brightest possible eyepiece image with full Plan correction. The instructor station handles all digital documentation and projection. This is the standard deployment pattern for university histology, microbiology, and hematology teaching laboratories. Ergonomic Advantages for Extended Slide Review The iScope's height-adjustable eye tubes accommodate users of different heights without neck strain — a feature absent from the bScope and BioBlue platforms. During extended slide review sessions (4+ hours in clinical or research settings), this adjustment prevents the chronic neck and shoulder pain that fixed-height microscopes cause. The rackless stage with low-mounted controls keeps the user's hands at a natural position, reducing wrist strain during frequent stage movements. These ergonomic details become significant when the microscope is in use 6-8 hours daily. Technical Specifications SKU: EIS-1152-PLI Microscope Type: Compound, binocular, brightfield Camera: No camera port (binocular head) Certification: CE certified Warranty: 10 years Need a camera port?
