AZDA1490 High-Contrast Coaxial Illumination Micoscope

Key Benefits

• Coaxial LED illumination delivers high brightness and consistent lighting on both high and low reflectivity surfaces
• 103mm working distance allows tools and fixtures to remain under the head during inspection
• Simultaneous visual and video output enables real-time observation and documentation
• Large depth of field improves focus stability across uneven or layered surfaces
• 1.4X to 9X zoom range covers locating, alignment and detailed inspection without changing objectives

Application Scenarios

• Inspecting LCD panels for defects with both reflective and non-reflective areas under the same illumination
• Checking planar printed circuit boards for solder bridges, missing pads or misaligned components
• Examining semiconductor wafers and chips where surface reflectivity varies across the sample
• Documenting inspection results with a digital camera while a technician observes through the eyepiece
• Performing quality checks on precision flat components in electronics, optics or materials science

Who It Is For

• Electronics manufacturers inspecting PCBs, LCDs and semiconductor components
• Quality control labs requiring consistent lighting on mixed-reflectivity surfaces
• Research labs working with planar materials such as wafers, thin films or printed electronics
• Production lines where both visual and digital records are needed for traceability
• Teaching labs demonstrating surface inspection techniques on flat, high-contrast samples

Problems It Solves

• Flat surfaces with mixed reflectivity lose detail under standard illumination; coaxial LED maintains contrast across the entire surface
• Standard microscopes require switching between visual and camera views, slowing down inspection
• Short working distances prevent tool access during rework or alignment tasks
• Low depth of field causes frequent refocusing on uneven or layered samples
• Lack of simultaneous video and visual output forces separate equipment or delayed documentation

Technical Features

• Original coaxial illumination optical system for high contrast and large depth of field
• LED illumination with long life, high brightness and multiple color options
• Binocular or trinocular head with 45° inclined eyetubes for ergonomic viewing
• Interpupillary adjustment 52mm~76mm and diopter adjustment ±6 diopter for user-specific fit
• 1.4X to 9X zoom range with 103mm standard working distance and 145mm/35mm optional
• Simultaneous visual observation through eyepieces and video output to a monitor
• Compatibility with 0.7X and 2X auxiliary objectives to extend magnification and working distance
• Support for 10X, 15X, 20X, 30X eyepieces and divisional eyepieces for flexible magnification
• CCD adapter and digital camera adapters available for integration with external imaging systems

Specifications

Specifications are taken from the AMADA product data for this item. Confirm critical dimensions with us in writing before ordering.

Customization Options

• Choose between binocular (ZDA1490BC) and trinocular (ZDA1490BTC) head configurations
• Add 0.7X or 2X auxiliary objectives to adjust working distance and magnification
• Select eyepieces from 10X to 30X to extend total magnification up to 540X
• Integrate with CCD adapter, digital camera adapters (DT01, PT02) or micrometer-equipped CDM1.0 adapter
• Mount on SD1-D to SD18-D stands; specify if mechanical stage S7665 or S10086 is required

Comparison With Other Options

Use Guide

• Adjust interpupillary distance between 52mm and 76mm before focusing to ensure merged binocular image
• Set the diopter on one eyepiece first, then focus with the other to avoid eye strain
• Use the 103mm working distance as a baseline; extend to 145mm or reduce to 35mm using auxiliary objectives
• Connect the camera via CCD adapter or digital camera adapter; ensure the adapter matches the sensor size
• For high-contrast surfaces like LCDs or wafers, use the coaxial LED illumination to minimize glare and shadow
