XSZ6745 2X Stereo Microscope Barlow Lens

The XSZ6745 is a 2X Barlow lens designed for use with stereo microscopes to increase magnification without changing objectives.

Product Overview

The XSZ6745 is a 2X Barlow lens designed for use with stereo microscopes to increase magnification without changing objectives. It fits into the optical path between the objective and the eyepiece, extending the effective magnification by a factor of two. This allows operators to achieve higher magnification levels while maintaining the same working distance and field of view characteristics of the original objective.

  • Magnification factor2X
  • Optical system compatibilityStereo microscope
  • Barlow lens typePositive lens
  • MaterialOptical glass
  • Surface treatmentAnti-reflective coating
  • Installation methodInsert into optical path between objective and eyepiece

Key Benefits

  • Doubles the magnification of any stereo microscope objective it is used with
  • Maintains the original working distance and field of view of the base objective
  • Enables inspection of fine details without replacing the objective or changing the setup
  • Simple to install and remove, allowing quick switching between magnification levels
  • Preserves stereo depth perception and optical clarity across the extended magnification range

Application Scenarios

  • Inspecting fine solder joints or micro-features on PCBs with a standard 1X objective
  • Examining surface defects or texture on small mechanical parts at higher magnification
  • Performing detailed inspection of electronic components without adjusting the stand or objective
  • Using in teaching labs where students need to switch between low and high magnification quickly
  • Supporting quality control checks on small parts where a higher magnification is needed temporarily

Who It Is For

  • Electronics manufacturers doing PCB, SMD and BGA rework and inspection
  • Teaching laboratories in electronics and engineering programs
  • Quality control teams requiring flexible magnification for inspection tasks
  • Precision assembly workshops in watchmaking and jewellery
  • Research and development labs working with small-scale components

Problems It Solves

  • A fixed magnification setup forces the operator to swap objectives to increase detail, disrupting workflow
  • Higher magnification objectives often reduce working distance, making hand tools unusable
  • Using separate high-magnification instruments adds cost and complexity to the inspection station
  • Lack of a quick magnification boost option slows down inspection and documentation
  • Changing objectives can misalign the optical path, requiring refocusing and recalibration

Technical Features

  • 2X magnification factor applied to the existing objective
  • Designed for use with stereo microscope optical systems
  • Fits between the objective and the eyepiece in the optical path
  • Maintains the original working distance and field of view of the base objective
  • Preserves stereo depth perception and image clarity
  • Compatible with standard 23mm and 30mm tube diameter microscopes

  • No alternative materials or coatings offered

Comparison With Other Options

Using a higher magnification objective insteadA 2X Barlow lens preserves working distance and field of view; a higher objective reduces working distance and may require a new stand or setup.
Using a zoom microscope with higher magnification rangeThe Barlow lens offers a fixed 2X boost without the cost or complexity of a full zoom system; it is a low-cost way to extend magnification.
No Barlow lens usedWithout the Barlow, the operator must switch to a higher objective to see fine details, which changes working distance and may require repositioning the sample or tools.

Use Guide

  • Ensure the microscope tube diameter matches the Barlow lens (23mm or 30mm)
  • Insert the Barlow lens into the optical path between the objective and the eyepiece
  • Do not force the lens; it should slide in smoothly without resistance
  • After installation, refocus the image using the microscope's focusing mechanism
  • Verify that the image remains clear and in stereo across the full magnification range
Answers

Frequently Asked Questions

What magnification does the XSZ6745 Barlow lens provide?

It provides a 2X magnification factor, doubling the effective magnification of the base objective.

Does using this lens change the working distance?

No. The working distance remains the same as the original objective.

Can I use this lens with any stereo microscope?

Yes, as long as the microscope has a 23mm or 30mm tube diameter and accepts a Barlow lens in the optical path.

Does the lens affect the field of view?

No. The field of view remains unchanged compared to the original objective.

Is the lens compatible with both binocular and trinocular heads?

Yes. It fits into the optical path regardless of head type, as long as the tube diameter matches.
