Novex Headmount Coarse Fine Drive 76mm Component Element

Description

Upgrading stereo boom stands with dual-stage focusing, the Novex Headmount Coarse Fine Drive 76mm Component Element provides 48mm of vertical travel along precision rack-and-pinion tracks. The fine drive delivers 2-micron increments for high-magnification tracking. Without an optical body or stand pillar, operation requires matching this 1.4 kg focus bracket to 32mm mounting columns.

A precision-machined aluminum casting features a 76mm internal receiver ring for stereo optical bodies and a 32mm vertical pillar bore. The 1.4 kg mechanical assembly incorporates coaxial coarse and fine focus knobs operating across a 48mm rack-and-pinion stroke. Coaxial fine gearing provides 2-micron vertical increments, paired with dual friction adjustment collars, a manual column stop safety collar, and 360-degree horizontal rotation around the mounting post.

Key Features of Novex Headmount Coarse Fine Drive 76mm Component Element

Assembly bench technicians, micro-welders, and quality assurance inspectors install this dual-speed bracket to achieve sub-micron focal control on standard 32mm boom stands. The coaxial fine drive allows operators to track thin focal planes at high zoom magnifications without the focal jumping typical of coarse-only mounts.

• Dual-stage coaxial coarse and fine focusing assembly block for stereo microscopes
• Precision 2-micron fine focus increments along a 48mm total rack-and-pinion travel stroke
• Standard 76mm internal diameter receiver ring fitting universal stereo zoom bodies
• Precision 32mm column bore designed for industry-standard vertical support pillars
• Integrated tension adjustment collar to eliminate downward drift under heavy camera loads
• Heavy-duty cast-aluminum construction weighing 1.4 kg for vibration-free rigidity
• Full 360-degree horizontal orientation pivoting around the vertical mounting column
• Includes a solid steel safety lock ring collar to prevent accidental vertical slippage

Coaxial Gearing Mechanics & Micro-Focal Physics

Coaxial fine focus gearing provides 2-micron vertical increments along precision rack-and-pinion tracks, allowing operators to dissect specimen layers that measure only fractions of a millimeter. The internal gear teeth are machined to tight tolerances, eliminating mechanical deadband and backlash when reversing focal direction under high-magnification stereo inspection.

Stand Compatibility & Tension Control

The 76mm receiver ring clamps optical zoom bodies securely with a knurled brass-tipped lock screw that prevents scratching the microscope chassis. The integrated tension collar adjusts rotation friction easily, ensuring the focus bracket stays parked at any vertical height even when supporting heavy trinocular camera attachments.

• Dual friction adjustment rings allow custom tuning of coarse focus rotational resistance
• Independent safety collar clamps to the 32mm pillar beneath the bracket to prevent accidental drops
• Precision 32mm pillar bore slides smoothly along vertical poles without binding
