What kind of samples can this microscope observe?

This biological microscope is primarily designed for observing transparent or semi-transparent samples, such as stained tissue sections, blood smears, cell cultures, and microorganisms on slides.

Is this unit suitable for darkfield or phase contrast microscopy?

While typically configured for brightfield, some models in this series can be adapted for darkfield or phase contrast with additional accessories. Buyers should confirm specific capabilities with the seller.

What maintenance is typically required for a microscope of this type?

Routine maintenance includes cleaning optical surfaces with appropriate lens cleaning solutions and cloths, ensuring the stage mechanism is free of debris, and replacing the halogen bulb when necessary.

Are spare parts and consumables readily available for Olympus CX series microscopes?

Yes, Olympus is a major manufacturer, and spare parts like bulbs, fuses, and replacement objectives for the CX series are generally available through specialist suppliers.

Can this microscope be connected to a camera for digital imaging?

Many Olympus CX series microscopes can be fitted with a trinocular head or a C-mount adapter to attach a digital camera for image capture. Buyers should verify if this specific unit includes such a port or if it can be added.

This listing is for the Olympus CX31RBSF Microscope.

The unit is in full working condition and is ready for immediate use.

Overview.

The Olympus CX31RBSF is an upright, binocular compound biological microscope, part of Olympus’s CX series known for its durable, ergonomic design and high-quality optics tailored for educational and routine clinical use.

Key Features & Specifications.

Optical System & Image Quality.

Utilizes the UIS 2 (Universal Infinity System) optical system, delivering bright, high-contrast images with excellent field flatness.

Equipped with Planned Achromat (PLCN) objectives offering superior sharpness and clarity across the field of view.

Features integrated anti-fungal treatment on optics to preserve performance in high-humidity environments.

Optical Components.

Eyepieces: Wide‑field binocular type (Field Number = 20), with a 30° inclination and interpupillary adjustment between 48‑75 mm.

Objectives (typical standard set):

Plan Achromats at 4×, 10×, 40×, and optionally 100× oil immersion (in some configurations).

Scribd.

Condenser: Built‑in Abbe condenser with NA of 1.25 (with oil immersion) and aperture iris diaphragm for precise illumination control.

Illumination & Stage.

Comes with a built‑in Köhler illuminator using a 6 V, 30 W halogen bulb.

Stage: Rackless design with a double-slide holder, complete with ergonomic tactile grips for smooth X‑Y movement; stage travel approx. 76 mm × 50 mm.

Ergonomics & Build Quality.

Featuring a rigid Y-frame, low-positioned coaxial coarse/fine focusing knobs, and pre‑focus upper limit to prevent contact with slides.

Integrated hand grips make transport within labs easy and safe.

Some models in the CX31 line include tilting binocular tubes, though CX31RBSF is typically fixed.

Dimensions & Operating Conditions.

Approx. 233 mm (W) × 411 mm (H) × 367.5 mm (D), weighing around 7.7–8 kg.

Designed for indoor use at altitudes up to 2000 m, ambient temperature range 5 °C to 40 °C, with humidity restrictions depending on temperature.
