Description
Engineered for directional shadow highlighting across metallic traces and mineral fractures, the Evident SZ51 Binocular Stereo Head Gooseneck Optics delivers 8x to 40x magnification across a 5:1 zoom span. Its Greenough optical design provides realistic stereoscopic relief. Oblique lighting creates deep contrast shadows, requiring frequent light pipe repositioning when manipulating irregular geological specimens.
The 1.2 kg optical block integrates lead-free Greenough zoom lenses covering 0.8x to 4.0x, configured without bulky ring light hardware to provide unobstructed side clearance for flexible gooseneck light pipes. Featuring a 45-degree binocular viewing head with 52mm to 76mm interpupillary spacing, this modular unit installs onto universal boom stands or post stands while requiring user-supplied eyepieces, focus blocks, and external illumination controllers.
Key Features of Evident SZ51 Binocular Stereo Head Gooseneck Optics
A specialized stereo zoom head configured for forensic analysis, geological fracture inspection, and precision rework requiring high-angle oblique illumination. The uncluttered objective nose allows dual-arm fiber optic or LED goosenecks to approach specimens at grazing angles for enhanced surface relief.
- Greenough optical system with a 5:1 zoom ratio delivering 8x to 40x magnification
- Continuous internal zoom mechanism operating from 0.8x to 4.0x
- Binocular observation head with 45-degree inclination for ergonomic viewing
- Interpupillary distance adjustment range from 52mm to 76mm
- Lead-free optical elements with broadband anti-reflection coatings
- Slim objective nose design providing unobstructed access for directional light guides
- Compact 1.2 kg modular head fitting standard 76mm focus carrier rings
- Generous 110mm working distance allowing manipulation with tweezers and soldering tips
Greenough Stereoscopy & Oblique Contrast Physics
The converging Greenough optical layout provides pronounced depth perception and high image contrast, crucial for identifying micro-fractures in metallurgical samples. Removing circular ring lights allows gooseneck light pipes to cast steep directional shadows, bringing subtle tool marks and crystalline facets into sharp, three-dimensional relief.
Boom Stand Mechanics & Optical Clearances
At 1.2 kg, this modular head integrates smoothly onto long-reach boom stands without inducing mechanical vibration during soldering. The zoom control knobs operate with smooth, grease-damped drag, and the open clearance around the lower lenses prevents interference when angling illumination guides close to specimens.
- Slim nosepiece profile accommodates tight gooseneck illumination angles down to 15 degrees
- Bilateral zoom knobs deliver smooth, continuous magnification transitions without play
- Universal 76mm body diameter drops cleanly into standard post and boom stand focus mounts
Evident Manufacturer Warranty & Inclusions
Evident Olympus protects this optical head with their standard 5-year limited warranty covering optical components and mechanical assembly. The complete factory package contains the Evident SZ51 binocular stereo zoom body, objective protection cap, and an instruction manual.
