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.

  • Optical SystemAchromatic
  • Thread InterfaceRMS 20.2mm
  • ApplicationBiological, Metallurgical, Polarizing
  • CorrectionChromatic and Spherical Aberration
  • Mount TypeComponent-level
  • Mounting MethodScrew-on via RMS 20.2mm thread

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 objectiveThe 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 sizeThe 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.
Answers

Frequently Asked Questions

What is the thread size of this objective?

The objective has an RMS 20.2mm thread interface, which fits standard microscope bodies with matching threads.

Can I use this objective with a digital microscope?

Yes, as long as the digital microscope has a compatible RMS 20.2mm mounting thread for the objective.

Is this objective suitable for biological samples?

Yes, it is designed for use in biological, metallurgical, and polarizing microscopes, including those used for tissue and cell examination.

Does this lens correct for chromatic aberration?

Yes, it is an achromatic objective, which reduces color fringing and improves image clarity across the field of view.

What magnification does this objective provide?

It provides 10X magnification when used with a 10X eyepiece, resulting in 100X total magnification.
