6.7X–45X Continuous Flat-Field Optics | Simul-Focal Design | 4 Interchangeable Bases
As a leading supplier of precision optical inspection instruments, Mikrosize is dedicated to delivering high-performance imaging solutions for factory quality control (QC) and material research labs.
When it comes to high-end optical inspection, leading global brands like Leica (S series), Olympus/Evident (SZ series), Zeiss (Stemi series), and Nikon (SMZ series) have long set the industry benchmarks for precision labs. However, for fast-paced mass production lines and cost-conscious QC departments, balancing premium optical performance with high return on investment (ROI) remains a critical challenge.
This is where our flagship optical solution, the Mikrosize iStereo-6745T Trinocular Stereo Microscope, comes in. Consistently recognized in optical trade reviews as a Top 10 cost-effective industrial stereo microscope, it bridges the gap between budget constraints and high-end imaging demands. Featuring premium multi-coated, flat-field optical components, it delivers distortion-free, high-contrast 3D stereoscopic imaging with sharp edge-to-edge definition. It offers a reliable, enterprise-grade alternative for universal defect detection without the premium brand markup, making it the ultimate tool for inspecting electronic components, PCBs, metal molds, plastic parts, and advanced material specimens.
1.Why Choose the iStereo-6745T?
lRanked among the top cost-effective industrial stereo microscopes globally, the iStereo-6745T is a full-featured continuous zoom microscope built for universal industrial defect detection and laboratory analysis.
lEffortless Zooming: Equipped with a 0.67X–4.5X zoom objective (6.7:1 ultra-wide zoom ratio), it supports flexible magnification expansion via interchangeable auxiliary lenses to meet ultra-fine observation demands.
lStay in Focus: Built with a high-precision optical transmission structure, this model realizes full parfocality across the entire zoom range—meaning you never have to refocus when changing magnification.
lTrue Simul-Focal Technology: The 45° inclined, 360° rotatable trinocular head allows the camera port and both eyepieces to be used simultaneously. Operators can view live images on a monitor without losing their stereoscopic view through the eyepieces, dramatically improving long-hour inspection efficiency and comfort.
lAmple Work Space: The standard effective working distance is 105 mm, which can be expanded from 30 mm to 287 mm using optional auxiliary objectives, leaving plenty of room for manual operations like soldering, assembly, and reworking.

5. Frequently Asked Questions (Q&A)
Q1: What is the benefit of a “Simul-Focal” trinocular head for industrial inspection?
A: On standard trinocular microscopes, engaging the camera port shuts off light to one of the eyepieces, forcing the operator to switch back and forth. The iStereo-6745T’s Simul-Focal design allows the camera port and both eyepieces to be active simultaneously. Your QC technicians can view a live HD stream on a monitor with team members while maintaining a true 3D stereoscopic view through the eyepieces, vastly increasing inspection efficiency during long shifts.
Q2: Does this microscope maintain focus when zooming in and out?
A: Yes. The iStereo-6745T is engineered with high-precision optical alignment that ensures full parfocality. Once you focus clearly at the maximum magnification, the sample will remain perfectly sharp and centered as you continuously zoom back down to macro view, eliminating the need for tedious micro-refocusing.
Q3: Is the iStereo-6745T compatible with third-party HDMI/USB industrial cameras?
A: Absolutely. The microscope features a standard CTV camera port. By pairing it with our optional 0.3X, 0.5X, or 1.0X C-mount adapters, you can seamlessly connect almost any standard industrial microscope camera, HDMI inspection camera, or high-speed digital sensor for real-time measurement and defect archiving.
Q4: We do precision electronics soldering. Is there enough room under the lens?
A: Yes, space is one of this model’s greatest strengths. It features a standard working distance of 105 mm, providing ample clearance for soldering irons, hot air guns, and tweezers. If you need even more room, attaching a 0.5X auxiliary objective expands the working distance up to 165 mm-177 mm (and up to 287 mm with a 0.3X lens) to accommodate larger workpieces.
