Evident SZX-ZB7 Stereo Zoom Main Block Component Element

Description

Serving as the core optical engine for modular research setups, the Evident SZX-ZB7 Stereo Zoom Main Block Component Element delivers 0.8x to 5.6x parallel zoom magnification across a 7:1 ratio. Parallel optical channels eliminate convergence distortion. Operating this modular zoom block requires pairing it with an external viewing tube, objective lens, and focus stand.

A precision cast-aluminum chassis houses lead-free Galilean optics with bilateral zoom controls and an integrated objective slider track. The 1.5 kg optical core incorporates a 360-degree rotational top interface ring to mount binocular or trinocular heads. Built without illumination or focusing gears, it drops into standard SZ2-STS focus blocks or column stands while accepting modular SZX2 plan apochromatic objectives, beam splitters, and camera adapters.

Key Features of Evident SZX-ZB7 Stereo Zoom Main Block Component Element

Materials testing labs, automated inspection integrators, and dissection research stations choose this core zoom block to configure customized Galilean stereo workstations. The parallel beam paths prevent trapezoidal image distortion, while the click-stop zoom mechanism provides exact magnification repeatability for comparative documentation.

• Galilean Common Main Objective core zoom block with an expansive 7:1 zoom ratio
• Internal parallel zoom channels operating smoothly from 0.8x to 5.6x
• Delivers 8x to 56x magnification when paired with standard 1x objective and 10x eyepieces
• Lead-free optical glass elements treated with broadband anti-reflection coatings
• Single objective mounting track with integrated data-link interface slot
• Compatible with modular SZX2 Achromat and Plan Apochromat objective series
• Standard circular dovetail mount supporting binocular, trinocular, and tilting heads
• Rigid 1.5 kg cast-aluminum housing fitting universal 76mm focus mount blocks

Galilean CMO Geometry & Modular Optical Physics

Passing parallel beam lines through independent zoom cylinders, the Galilean CMO system eliminates convergence distortion, providing perpendicular optical axes that prevent image tilt during photomicrography. Internal optical surfaces feature broadband antireflective multicoatings that suppress internal glare, preserving high image contrast when paired with external coaxial or high-angle gooseneck illumination.

Gantry Integration & Mechanical Action

Integrating into standard focus carriers and custom machine-vision gantries, the 1.5 kg aluminum chassis resists mechanical flex under heavy intermediate attachments. The bilateral zoom dials operate with grease-damped drag across calibrated click-stops at 0.8x, 1x, 1.25x, 1.6x, 2x, 2.5x, 3.2x, 4x, 5x, and 5.6x, ensuring exact magnification recall.

• Bilateral zoom knobs provide balanced, backlash-free adjustment across all ten click-stops
• Integrated objective track allows rapid lens swapping without dismounting illumination rings
• Rotational top dovetail enables 360-degree orientation of attached observation tubes
