195 Achromatic Microscope Objective Lens RMS 20.2mm
The 195 Achromatic Microscope Objective Lens RMS 20.2mm is a component-level objective designed for use in biological, metallurgical, and polarizing microscopes.

Product Overview
The 195 Achromatic Microscope Objective Lens RMS 20.2mm is a component-level objective designed for use in biological, metallurgical, and polarizing microscopes. It provides 10X magnification with a 0.25 numerical aperture and a 20.2mm RMS thread interface, allowing direct mounting on standard microscope bodies. The lens corrects for chromatic and spherical aberration, ensuring clear, sharp imaging across the field of view.

Key Benefits
- 10X magnification with 0.25 NA for detailed inspection of small features
- RMS 20.2mm thread interface fits standard microscope bodies with no adapter needed
- Achromatic correction reduces color fringing and improves image clarity
- Designed for use in biological, metallurgical, and polarizing microscope systems
- Component-level supply allows direct replacement or upgrade without changing the entire stand
Application Scenarios
- Replacing a damaged or worn objective on a biological microscope used in teaching labs
- Upgrading a metallurgical microscope for higher resolution inspection of metal surfaces
- Reconfiguring a polarizing microscope for mineral or crystal analysis with a corrected objective
- Matching a new objective to an existing microscope body without changing the optical train
- Using in a quality control lab where consistent magnification and image clarity are required
Who It Is For
- Teaching laboratories requiring reliable, replaceable objectives for student use
- Clinical and veterinary labs performing routine tissue or specimen examination
- Metallurgy and materials testing labs inspecting grain structure and surface defects
- Research labs conducting polarized light microscopy on minerals or crystals
- Maintenance teams replacing worn objectives on existing microscope stands
Problems It Solves
- A damaged objective lens forces a lab to stop inspection until a replacement is sourced
- Mismatched thread sizes between objectives and microscope bodies require adapters or new stands
- Uncorrected chromatic aberration causes blurry, colored edges in images, reducing inspection accuracy
- Lack of standardization across objectives makes it hard to swap lenses between instruments
- No component-level supply forces buyers to replace entire microscope systems for a single lens
Technical Features
- Achromatic optical design corrects for chromatic and spherical aberration
- 10X magnification with 0.25 numerical aperture for balanced resolution and depth of field
- RMS 20.2mm thread interface for direct mounting on compatible microscope bodies
- Designed for use in biological, metallurgical, and polarizing microscope systems
- Clear, sharp imaging across the field of view without color fringing

Comparison With Other Options
| Non-achromatic 10X objective | The 195 lens corrects for chromatic aberration, reducing color fringes at the edges of the image, while a non-achromatic lens may show blurring or color halos. |
|---|---|
| 10X objective with different thread size | The RMS 20.2mm interface ensures direct compatibility with standard microscope bodies; other thread sizes require adapters or may not fit at all. |
| Higher magnification objective (e.g. 20X) | The 10X lens offers greater working distance and field of view, making it better suited for general inspection and handling of larger samples. |
