XSZ6745 0.7X Stereo Microscope Barlow Lens

Product Overview

The XSZ6745 0.7X Barlow lens is an optical accessory for stereo microscopes that extends the working distance and reduces magnification. It fits into the optical path between the objective and the eyepiece, allowing a standard 1X objective to deliver 0.7X magnification while increasing the working distance by approximately 43%. This enables operators to work with larger components or tools under the optics without interference.

Key Benefits

Increases working distance by approximately 43% when used with a 1X objective
Reduces magnification to 0.7X, so larger areas can be viewed at once
Maintains stereo depth perception across the full field of view
Allows use of a soldering iron, probe or tool under the optics without obstruction
Compatible with standard stereo microscope bodies using 1X objectives

Application Scenarios

Inspecting large PCBs or assemblies where a standard working distance is too short
Performing rework on components with high-profile parts or connectors
Using a soldering iron or hot air pencil under the microscope without touching the optics
Working with large mechanical parts or moulded components in precision assembly
Enabling tool clearance during micro-soldering or wire bonding under the head

Who It Is For

Electronics rework and repair benches handling large or high-profile components
Precision assembly workshops in watchmaking, jewellery and micro-mechanics
Quality inspection teams working with large or bulky parts
Teaching labs where students need space for tools during hands-on sessions
Manufacturing lines requiring tool clearance during inspection of large assemblies

Problems It Solves

Standard 1X objectives have limited working distance, forcing operators to move tools out of the way
Lack of tool clearance under the optics leads to repeated repositioning or missed joints
Fixed magnification limits the ability to view both large areas and fine details without changing objectives
No optical solution exists to extend working distance without sacrificing stereo vision
Operators must use a separate low-magnification stand or switch to a different microscope

0.7X magnification factor when used with a 1X objective

Comparison With Other Options

Standard 1X objective without Barlow lens	The 0.7X Barlow increases working distance by 43% and reduces magnification, allowing tool clearance under the optics without changing objectives.
0.5X Barlow lens	The 0.7X Barlow provides less magnification reduction and less working distance increase than a 0.5X lens, but maintains a higher image brightness and field clarity.
Auxiliary 0.5X objective	The Barlow lens is a non-contact optical insert that does not require changing the objective; it preserves the original objective's focus and mounting.

Use Guide

Ensure the microscope is set to a 1X objective before installing the Barlow lens
Insert the Barlow lens into the optical path between the objective and the eyepiece
Check that the lens is fully seated and aligned to avoid image distortion
Focus the microscope at the new 0.7X magnification setting
Verify that the working distance has increased and that tools can now pass under the optics
