Description
Eliminate workbench chatter during high-magnification semiconductor failure audits using the Kern OZM 922 Double Boom Microscope. Built on a massive 515 x 614 mm solid steel baseplate, this 30.0 kg free-standing platform delivers absolute anti-vibration stability without table clamps or mounting holes. Its double-arm boom rides on sealed linear ball bearings, providing 470 mm of smooth horizontal glide over large silicon wafers and aerospace subassemblies.
Powered by a 0.7x to 4.5x Greenough twin-path optical engine (1:6.4 zoom ratio), it delivers continuous 7x to 45x magnification across super-widefield high-eyepoint HSWF 10x/23 mm eyepieces. Bilateral diopter equalization sleeves balance visual focus across a 52 mm to 76 mm interpupillary range. Surface illumination is supplied by an objective-mounted 4.5W circular LED ring light with an inline rotary rheostat, flooding reflective parts with shadowless white light. The 380 mm vertical steel column provides generous clearance for tall fixtures, operating on universal 100-240V AC power.
Key Features of Kern OZM 922 Double Boom Microscope
A heavy-duty binocular stereo zoom research microscope featuring an ultra-stable double-arm boom stand, a maximum 515 x 614 mm steel baseplate, and a 4.5W LED ring light. Combines 7x to 45x magnification with super-wide 23 mm eyepieces, 470 mm horizontal slide stroke, 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
- Maximum-sized 515 x 614 mm solid steel baseplate delivers 30.0 kg of vibration-isolated ballast
- 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
- Bilateral diopter adjustment sleeves on both ocular tubes balance visual focus
- Solid 380 mm vertical steel column accommodates deep specimen clearance heights
Double-Arm Ball-Bearing Glide & Linear Board Scanning
Single-boom arms tend to bind or pitch off-axis under heavy manipulation, 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 Greenough optical paths produce genuine 3D spatial depth, making delicate hand-soldering and trace repair feel completely natural.
30kg Massive Steel Ballast & Shadowless Ring Light
At 30.0 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 manipulation
- Massive 30 kg baseplate keeps the center of gravity low even at maximum 470 mm reach
- Bilateral diopter rings balance visual focus for technicians wearing corrective eyewear
