XT Series Stereo Microscope

XT3B 10/20/30/40X Stereo Microscope

Name: XT3B 10/20/30/40X Stereo Microscope
Brand: AMADA Microscope

The XT3B is a free articulated binocular stereo microscope with a 45° inclined head and rack and pinion focusing.

Product Overview

The XT3B is a free articulated binocular stereo microscope with a 45° inclined head and rack and pinion focusing. It uses a WF10X/18mm eyepiece and allows selection of any two objectives from 1X, 2X, 3X, and 4X. Working distances vary by objective: 55mm at 1X, 81mm at 2X, 61mm at 3X, and 57mm at 4X. It includes top illumination with a 12V/10W halogen lamp and a black-white reversible stage plate. The unit weighs 2.2kg and is designed for bench-level inspection and assembly tasks.

Key Benefits

Free articulated binocular head allows flexible positioning for operator comfort and task access
45° inclined head reduces neck strain during prolonged inspection or assembly
Rack and pinion focusing with adjustable torque provides smooth, precise focus control
Working distance up to 81mm at 2X objective allows room for tools, probes, or components under the optics
Selectable objectives from 1X to 4X let the same instrument cover multiple magnification needs without changing stands
Top illumination with 12V/10W halogen lamp provides even lighting for reflective surfaces
Black-white reversible stage plate supports both transparent and opaque sample inspection
Optional WF15X and WF20X eyepieces extend magnification to 30X and 40X respectively

Application Scenarios

Electronics assembly and rework where a soldering iron or probe must fit under the optics
Precision watchmaking or jewellery assembly with tools operating under the head
Inspection of small mechanical parts, connectors, or moulded components on a bench
Teaching or demonstration in a lab where multiple users view the same sample
Quality inspection of surface features on metal, plastic or ceramic parts using top light

Who It Is For

Electronics manufacturers doing SMD and BGA rework and inspection
Jewellery, watchmaking and precision assembly workshops
Teaching laboratories in technical schools and vocational training centers
Quality control teams in manufacturing plants using visual inspection for incoming or in-process checks
Research labs conducting surface-level analysis of small components

Problems It Solves

Fixed head microscopes require repositioning the entire stand to change viewing angle
Short working distances at higher magnifications prevent tool use under the optics
Lack of adjustable focus torque leads to over-tight or loose focusing during inspection
Single objective stands require frequent changes when switching between locating and detailed inspection
No top illumination forces the use of external lights that may create shadows or glare

Technical Features

Working distances: 55mm (1X), 81mm (2X), 61mm (3X), 57mm (4X)
Top illumination with 12V/10W halogen lamp for consistent surface lighting
Ф60mm black-white reversible stage plate for transparent or opaque sample support
WF10X/18mm standard eyepiece with plan-scope design for flat field of view
Arm-type pole stand for stable mounting on a bench or worktable
Net weight 2.2kg for easy handling and repositioning

Customization Options

Choose any two objectives from 1X, 2X, 3X, and 4X to set the working distance and magnification
Upgrade to WF15X or WF20X eyepieces for higher magnification up to 30X or 40X
Replace halogen lamp with an optional LED lamp for lower heat and longer life
Select a different stage plate or add a stage accessory if needed for specific sample types
Mount on a different stand type if required for space or workflow constraints

Comparison With Other Options

Fixed head stereo microscope	The XT3B's articulated head allows repositioning without moving the stand, improving access during tool-based work
Microscope with fixed working distance	The XT3B offers four objective options with varying working distances, so the same stand supports both broad and detailed inspection
Microscope with no adjustable focus torque	The XT3B's rack and pinion system allows torque adjustment, reducing focus drift and improving control during long sessions

Use Guide

Adjust the interpupillary distance to 55~75mm before focusing to ensure a single merged image
Set the objective combination before starting; changing objectives mid-task requires refocusing
Use the 2X objective (81mm working distance) when tools like soldering irons or probes must fit under the head
Position the halogen lamp to avoid glare on shiny surfaces; use the black side of the stage for reflective samples
For higher magnification, switch to WF15X or WF20X eyepieces and adjust focus accordingly
If using an LED lamp, ensure it is compatible with the existing power supply and mounting
