Description
Document fine PCB micro-cracks and capture live defect video using the Kern OZM 923 Double Boom Microscope. Its double-arm boom extends 470 mm horizontally across twin parallel steel rails, gliding on dual ball bearings to eliminate the sagging or binding common to single-arm stands under heavy optical loads. Powered by a 0.7x to 4.5x Greenough zoom engine (1:6.4 ratio), it delivers continuous 7x to 45x magnification across super-widefield high-eyepoint HSWF 10x/23 mm eyepieces. A top vertical photo port with an integrated beam splitter routes light to digital C-mount cameras while keeping both oculars active.
The unit anchors to a heavy 430 x 480 mm solid steel baseplate finished in a scratch-resistant industrial coating, bringing total assembly mass to 24.5 kg for rock-solid vibration isolation in high-traffic workshops. Surface illumination is handled by an objective-mounted 4.5W circular multi-segment LED ring light with an inline rotary rheostat, delivering shadowless daylight-balanced lighting over deep component wells. Dual-sided coarse focus knobs with internal tension adjusters glide along a 380 mm vertical pillar, operating on universal 100-240V AC power with zero desk-drilling requirements.
Key Features of Kern OZM 923 Double Boom Microscope
A professional trinocular Greenough stereo zoom research microscope featuring an ultra-stable double-arm boom stand, a 430 x 480 mm steel baseplate, and a 4.5W LED ring light. Combines 7x to 45x magnification with super-wide 23 mm eyepieces, a vertical camera port, and dual-rail ball-bearing guidance.
- Continuous 7x to 45x zoom magnification powered by an 0.7x to 4.5x Greenough engine
- Double-arm boom with linear ball bearings provides 470 mm of effortless horizontal stroke
- Solid 430 x 480 mm steel counterweight baseplate delivers 24.5 kg of vibration-free ballast
- Dedicated vertical photo tube port with internal beam splitter for digital camera archiving
- Objective-mounted 4.5W circular LED ring light provides uniform, shadow-free illumination
- Super-widefield HSWF 10x/23 mm high-eyepoint eyepieces provide an expansive visual field
- Greenough stereoscopic layout yields genuine 3D spatial depth for delicate tool handling
- Solid 380 mm vertical steel column accommodates deep specimen clearance heights
Double-Arm Ball-Bearing Glide & Linear Board Scanning
Single-boom arms can bind or pitch off-axis when carrying heavy cameras, but the twin hardened steel rails on this stand distribute weight evenly across sealed ball-bearing sleeves. Technicians can glide the optical head across heavy casting housings and wide electronic chassis with fingertip force. The top-mounted vertical photo tube routes optical data directly to digital C-mount cameras, letting materials engineers capture publication-grade photomicrographs while actively viewing through the oculars.
24.5kg Solid Steel Ballast & Shadowless Ring Light
At 24.5 kg, this heavy free-standing base eliminates the need for through-table bolts or edge clamps that could damage expensive workbenches. The scratch-resistant industrial coating shrugs off shop-floor wear, while the low center of gravity stops forward tipping during aggressive scanning passes over wide assemblies. The circular 4.5W LED ring light surrounds the objective lens, eliminating dark corners inside deep component wells and suppressing blinding highlights on shiny solder pads.
- Dual-rail boom design stops optical head twisting and sagging under heavy camera loads
- Heavy-duty steel baseplate keeps the center of gravity low even at maximum 470 mm reach
- Vertical photo port allows simultaneous eyepiece viewing and digital documentation
