BoliOptics 100mm Clear Glass Microscope Stage Plate - Precise Fit

Our review of the BoliOptics 100mm Diameter Clear Glass Microscope Stage Plate finds it to be a straightforward replacement or upgrade for hobbyists and lab technicians who need a clean, flat viewing surface. The biggest reason to buy is its simple, reliable construction: a full 100mm diameter glass disc at a consistent 2.5mm thickness that fits most standard microscope stages. The plate is uncoated clear glass, which keeps imaging predictable and makes cleaning easy, so it is best for users who want a no-frills, durable stage plate rather than additional specialty coatings or apertures.

Key Features

• 100mm Diameter: Provides a large, nearly 4 in clear surface that accommodates common slide sizes and allows easier positioning of samples without crowding.
• 2.5mm Thickness: The moderate glass thickness balances rigidity and weight so the plate sits flat without excessive flex during routine use.
• Clear Optical Glass: Uncoated transparency preserves true color and contrast for transmitted light and darkfield observation.
• Simple Replacement Design: The round plate shape and standard sizing make this easy to swap into most microscope stage setups that accept a loose glass disc.
• Easy Maintenance: Smooth glass surface wipes clean with lens solution or alcohol without special care, reducing downtime between samples.

Who It's For

This stage plate is aimed at hobby microscopists, students, and lab techs who need a dependable, plain glass surface for brightfield or transmitted-light work. Its 100mm size and 2.5mm thickness suit general-purpose observation and imaging where a flat, unobstructed field is required.

It is not meant for users who require specialized coatings, pre-drilled holes, or integrated apertures for phase or fluorescence work; those users should look for stage plates specified for those techniques. Also, those needing custom-cut shapes or integrated mounting tabs should consider purpose-built alternatives.

Pros & Cons

Pros

• Large 100mm diameter gives more usable area for aligning slides and samples.
• 2.5mm thickness provides a stable, flat surface that resists flex under normal handling.
• Clear, uncoated glass delivers predictable optical transmission and is easy to clean.

Cons

• Plain glass means no specialty coatings or drilled features for advanced microscopy techniques.

Frequently Asked Questions

Will this plate fit my standard microscope stage?
The 100mm diameter is a common size and will fit many stages that accept a loose round plate, but users should measure their stage opening to confirm compatibility.

Is the glass coated for anti-reflective or scratch resistance?
No, this model is plain clear glass without specialty coatings, chosen for predictable transmission and easy cleaning.

How thick is the plate and why does that matter?
The plate is 2.5mm thick, which offers a good balance of rigidity and manageable weight so it sits flat under normal use.
