Cole-Parmer Model 48923 Integrated Digital Microscope System

Overview

The Cole-Parmer Model 48923 Integrated Digital Microscope System is a purpose-engineered optical instrument combining high-fidelity transmitted-light microscopy with built-in digital imaging capability. Designed for routine laboratory use in quality control, educational instruction, and basic research environments, this system operates on standard Köhler illumination principles using an Abbe condenser (NA 1.25) and interchangeable achromatic objectives—including a 100× oil-immersion lens—ensuring consistent resolution and contrast across magnifications from 40× to 1000×. Unlike modular microscope-camera setups requiring separate alignment, calibration, and software integration, the Model 48923 features a factory-aligned CMOS sensor mounted directly within the optical path, eliminating parallax error and ensuring pixel-registered image capture at all magnifications. Its dual-path illumination selector enables real-time parallel viewing: simultaneous analog observation via binocular head and digital acquisition without optical compromise.

Key Features

• Integrated 5-megapixel CMOS imaging module with adjustable exposure control, white balance, and real-time histogram display
• Binocular viewing head with interpupillary adjustment (55–75 mm), 10× wide-field (18 mm) eyepieces, rubber eyecups, and integrated crosshair pointers
• Four-position revolving nosepiece with precision ball-bearing mounting for smooth, backlash-free objective switching
• Abbe condenser (NA 1.25) with iris diaphragm, centering screws, focusing helix, and pull-out filter holder accommodating blue, green, and yellow interference filters
• Sturdy cast-aluminum frame with vibration-damped base (160 × 220 mm); ergonomic 45° inclined eyepiece tube with quick-release mechanism
• Coaxial mechanical stage (70 × 50 mm travel range, 0.1 mm scale graduation) with low-profile X-Y controls and specimen clamp
• Dual-focus system: coarse focus with tension-adjustable rack-and-pinion drive and slip-clutch protection; fine focus with 0.002 mm vernier scale and lock mechanism
• Integrated anti-crash safety: objective stop mechanism prevents contact between immersion lens and slide during focusing

Sample Compatibility & Compliance

The Model 48923 supports standard 1″ × 3″ glass slides and coverslips (0.13–0.17 mm thickness) under both dry and oil-immersion conditions. It accommodates routine histological sections, microbiological smears, metallurgical mounts, and polymer thin films. The optical train conforms to ISO 8578:2017 (microscope mechanical tube length and parfocality requirements) and complies with IEC 61000-6-3:2019 for electromagnetic compatibility in laboratory environments. All electronic components meet UL 61010-1 safety standards for electrical equipment used in laboratory settings. While not validated for regulated GxP workflows, the included software supports audit-trail-enabled image metadata logging (timestamp, operator ID, magnification, objective used, exposure settings), facilitating traceability in GLP-aligned documentation practices.

Software & Data Management

The bundled Windows®-compatible application (v3.x, 64-bit, compatible with Windows 10/11) provides native TIFF, JPEG, and BMP export; on-screen measurement tools (linear, area, angle, particle count); annotation layers with text, arrows, and ROI masking; and synchronized audio commentary recording linked to individual image captures. Image metadata—including objective identification, magnification, exposure time, gain, and color profile—is embedded in EXIF tags. Batch export and folder-based project organization are supported. Software installation includes optional DICOM header mapping for limited PACS interoperability in academic pathology labs. No cloud dependency or subscription licensing is required; all functionality is locally executed and data remains resident on the host PC.

Applications

• Routine QC inspection of pharmaceutical tablet coatings and excipient particle morphology per USP
• Microbiological examination of Gram-stained clinical isolates and environmental swab samples
• Educational life science laboratories requiring student-accessible, maintenance-minimal imaging platforms
• Materials science labs performing basic metallographic grain analysis and polymer phase distribution assessment
• Forensic document examination involving ink differentiation and fiber identification at ≥400× magnification
• Botanical and mycological specimen documentation with calibrated scale bar overlays

FAQ

Does the microscope support live HDMI output for external monitors or projectors?
Yes—the system includes an HDMI port enabling real-time 1080p video streaming independent of the host PC.
Is oil-immersion operation compatible with the digital camera path?
Yes; the optical design maintains full NA transmission through the 100× oil objective into the sensor plane without vignetting or resolution loss.
Can measurement data be exported to CSV or Excel formats?
Linear and area measurements can be copied to clipboard as tab-delimited values for direct pasting into spreadsheet applications.
What is the maximum frame rate at full sensor resolution?
The camera delivers 15 fps at 2592 × 1944 pixels and 30 fps at 1280 × 960 pixels—sufficient for dynamic cellular observation and focus stacking workflows.
Are replacement objectives or accessories available through Cole-Parmer?
Yes; standard DIN 23.2 mm thread objectives (4×, 10×, 40×, 100× oil), spare filters, immersion oil, and stage micrometers are stocked and warrantied under Cole-Parmer’s standard terms.
