Evident SZ61 Trinocular Stereo Head Gooseneck Optics Tool

Description

Directing high-contrast grazing illumination across fractured toolmarks, the Evident SZ61 Trinocular Stereo Head Gooseneck Optics Tool delivers continuous 6.7x to 45x zoom magnification across a 6.7:1 ratio. Widefield 10x eyepieces provide a 22mm field number. The Greenough optical layout renders deep spatial relief, though steep oblique lighting creates dense shadows across deep crevices.

The 2.3 kg modular assembly combines lead-free Greenough optics with a dual-arm semi-rigid flexible LED gooseneck system and an independent tabletop controller. Built with a 45-degree inclined trinocular head offering 52mm to 76mm interpupillary spacing and a vertical documentation port, it fits universal 76mm focus collars while maintaining an open 110mm working distance to maneuver light guides close to botanical or forensic specimens.

Key Features of Evident SZ61 Trinocular Stereo Head Gooseneck Optics Tool

Forensic examiners, toolmark investigators, and botanical taxonomists select this gooseneck-equipped stereo head to cast steep directional lighting across irregular surface topographies. The flexible dual-arm LED pipes allow independent angle and intensity adjustment, highlighting micro-grooves and fracture facets that disappear under flat illumination.

• Greenough optical system with a 6.7:1 zoom ratio delivering 6.7x to 45x magnification
• Continuous internal zoom mechanism operating smoothly from 0.67x to 4.5x
• Trinocular viewing tube with 45-degree fixed inclination and dedicated vertical camera port
• Widefield Comfort NCWH 10x eyepieces with an expansive 22mm field number (FN 22)
• Dual-arm semi-rigid flexible LED gooseneck lighting system for customized cross-illumination
• Independent tabletop electronic controller featuring dual analog brightness dials
• Generous 110mm standard working distance providing ample clearance for tools and light pipes
• Modular 2.3 kg optical block compatible with heavy-duty boom stands and articulating arms

Greenough Stereoscopy & Oblique Cross-Lighting

Bypassing circular ring lights allows semi-rigid flexible gooseneck light pipes to project steep grazing illumination at angles as low as fifteen degrees. The converging Greenough optical paths capture the resulting high-contrast relief shadows, resolving microscopic striations on ballistics evidence, crystalline fractures, and insect cuticles with vivid three-dimensional separation.

Gooseneck Mechanics & Optical Clearances

Dual analog dials on the tabletop power block regulate each gooseneck arm independently, letting technicians balance direct spotlighting against softer fill illumination. The semi-rigid pipes hold their bend position securely without sagging, and the uncluttered objective nose leaves plenty of working space for tweezers, scalpel blades, and probe fixtures.

• Semi-rigid gooseneck arms maintain precise directional angles without creeping down
• Dual potentiometer dials allow independent intensity tuning for both illumination channels
• Standard 76mm body mount fits universal boom stands and track pillars without modification
