2X 5X 10X 20X 50X 100X 95mm M Plan APO Microscope Objective

The 95mm M Plan APO objective series includes six magnifications from 1X to 100X, each with a 95mm mechanical tube length and a precision optical design.

Product Overview

The 95mm M Plan APO objective series includes six magnifications from 1X to 100X, each with a 95mm mechanical tube length and a precision optical design. These objectives are designed for use with standard 1" eyepieces and camera adapters, providing consistent focus and resolution across a range of inspection tasks in metallurgical, biological, and industrial applications. The series includes both standard and high-luminosity variants, with working distances from 6mm to 135mm and numerical apertures from 0.025 to 0.70.

  • Biological sample examination under brightfield or transmitted light with 5X to 10X objectives
  • Precision component inspection in electronics with 50X and 100X objectives for fine detail
  • Quality control of machined parts where a 20X or 50X objective provides sufficient depth of focus
  • Microscopy training where multiple magnifications are used on a single instrument

Who It Is For

  • Metallurgy and materials testing labs
  • Electronics manufacturing quality teams
  • University and technical school teaching labs
  • Industrial inspection and maintenance teams
  • Research labs requiring consistent optical performance across magnifications

Problems It Solves

  • Mismatched tube length between objectives and microscope bodies causes focus shift and image distortion
  • Low numerical aperture objectives fail to resolve fine surface features at high magnification
  • Inconsistent working distance across objectives forces frequent sample repositioning
  • Lack of depth of focus at high magnification makes it hard to keep entire features in focus
  • Incompatible threading or mounting between objectives and camera adapters prevents digital imaging

Technical Features

  • 95mm mechanical tube length for standard compatibility with microscope bodies and camera adapters
  • M Plan APO optical system with apochromatic correction for reduced chromatic aberration
  • Working distances from 6mm to 135mm depending on magnification and objective type
  • Numerical apertures from 0.025 to 0.70, supporting high resolution at 100X
  • Resolution ratios from 0.4μm to 11.0μm, with depth of focus from 0.56μm to 440μm
  • Field of view ranges from 0.1x0.13mm to 24x32mm depending on magnification
  • Available in standard and high-luminosity (HL) variants for improved brightness at high magnification

Comparison With Other Options

Standard achromatic objectivesM Plan APO objectives offer superior chromatic correction and higher resolution at 50X and 100X, reducing color fringing and improving edge clarity
75mm tube length objectives95mm objectives are compatible with a broader range of microscope bodies and camera systems, reducing the need for adapters
Non-AP objectivesM Plan APO design ensures consistent focus and resolution across the zoom range, minimizing focus shift when switching between magnifications

Use Guide

  • Ensure the microscope body has a 95mm mechanical tube length before mounting
  • Use the correct objective for the required working distance and magnification
  • For 100X objective, use immersion oil if specified in the application
  • Clean the lens surface with lens paper before and after use to prevent scratches
  • Do not force the objective into the nosepiece; align the mounting flange and gently tighten
Answers

Frequently Asked Questions

What is the mechanical tube length of this objective?

95mm. This ensures compatibility with standard microscope bodies and camera adapters.

Can I use this objective with a digital camera?

Yes. The 1" mounting thread is compatible with C-mount and standard 1" camera adapters.

What is the working distance at 100X magnification?

6mm. This is suitable for thin samples or high-magnification inspection with minimal clearance.

Are these objectives compatible with 1" eyepieces?

Yes. The objective is designed for use with 1" eyepieces and has a 24mm field lens diameter.

Do I need immersion oil for the 100X objective?

Yes, if the application requires maximum resolution. Use immersion oil with the 100X objective for optimal performance.

What is the difference between standard and HL variants?

HL (High Luminosity) variants provide brighter images at high magnifications, especially useful for 20X and above.
