What kind of samples can this microscope be used for?

This type of biological microscope is suitable for observing transparent or stained samples on slides, such as blood cells, tissue sections, bacteria, and other microorganisms.

Is this microscope suitable for fluorescence microscopy?

The standard CX31RBSF model is designed for brightfield observation. It does not typically include fluorescence capabilities without specific modifications or accessories.

What maintenance is required for this microscope?

Regular maintenance typically involves cleaning optical surfaces, checking the bulb and fuse, and ensuring the stage and focus mechanisms operate smoothly. Anti-fungal treatment helps reduce internal mould growth.

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

While not always standard, many microscopes of this type can be adapted for digital imaging by adding a trinocular head or a C-mount adapter and a compatible camera. Buyers should confirm specific compatibility with the seller.

What is the benefit of the UIS2 optical system?

The UIS2 (Universal Infinity System) optical system typically provides excellent image flatness, high contrast, and true-to-life colour reproduction, which is beneficial for accurate observation and documentation.

Are spare parts and consumables readily available for this model?

As a common model from a major manufacturer, spare parts like bulbs and fuses, and consumables such as immersion oil and cleaning supplies, are generally widely available.

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.
