What is the significance of 'PH.1' on the objective?

PH.1 indicates that this objective is designed for phase contrast microscopy, specifically for a phase ring of a certain size. This technique enhances the visibility of transparent specimens by converting phase shifts into brightness differences.

Will this objective fit my existing microscope?

This objective typically features an RMS thread, which is a common standard for many older Vickers, Cooke-Baker, and other compatible microscope stands. Buyers should verify their microscope's objective thread type for compatibility.

What kind of specimens is this 10x phase contrast objective best suited for?

A 10x phase contrast objective is ideal for observing live, unstained biological samples such as cells in culture, protozoa, or thin tissue sections where high contrast is needed without staining.

What maintenance is required for microscope objectives?

Maintenance typically involves keeping the lens surfaces clean and free of dust, oil, and fingerprints using appropriate lens cleaning solutions and cloths. Avoid touching the lens surfaces directly.

Can this objective be used for fluorescence microscopy?

While technically possible, phase contrast objectives are not optimised for fluorescence microscopy. They may introduce unwanted autofluorescence or reduce light transmission compared to dedicated fluorescence objectives.

This listing is for the Vickers Microplan 10X Microscope

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

: Vickers Microplan 10× Microscope Objective

This is an objective lens—part of a microscope optical system—rather than an entire microscope unit. The specific lens in question is marked "Vickers England MICROPLAN 10/0.25 + PH.1", indicating a 10× magnification and a numerical aperture (NA) of 0.25. The “PH.1” denotes that it includes phase-contrast capabilities

Typical length around 37–39 mm, and weight in the range of 58–63 g

Usage and Value

These objectives, with their phase-contrast capability, were designed to be used with microscopes that support such optical techniques.

This objective would typically fit an RMS-threaded turret, common in Vickers, Cooke‑Baker, or similar stands

The phase ring (PH.1) allows enhanced imaging of transparent specimens, by shifting phase differences into contrast—ideal for biology or unstained sample observation.

Typical context for this category of equipment. Always confirm specifics with the seller.

Applications & Use Cases

Biological research and cell culture observation.
Pathology and histology for tissue analysis.
Quality control in manufacturing for small component inspection.
Educational settings for microscopy instruction.
Material science for examining surface structures.

Typical Specifications

Magnification: This specific objective provides 10x magnification. Other objectives for this class of equipment typically range from 2x to 100x.
Numerical Aperture (NA): This objective has an NA of 0.25, indicating its light-gathering ability and resolution. NAs for similar objectives commonly range from 0.05 to 1.4.
Optical Correction: This is a Microplan objective, indicating good flatness of field. Objectives of this type often feature achromatic or plan-achromatic corrections.
Thread Type: Typically, Vickers objectives use the Royal Microscopical Society (RMS) thread standard, which is common across many older microscope brands.
Phase Contrast Capability: The 'PH.1' designation indicates phase contrast, allowing observation of unstained, transparent specimens. Not all objectives for this class of equipment include this feature.
Working Distance: For a 10x objective of this type, the working distance is typically a few millimetres, allowing space between the objective and the specimen.
