AI Technical Summary
Existing lever-type variable magnification monotube microscopes and continuous zoom monotube microscopes suffer from unstable imaging and high costs during adjustment. Lever-type variable magnification devices are inaccurate in adjustment, while continuous zoom devices are complex to manufacture and costly, and their imaging fails after wear.
The system employs a combined adjustment method, where the distance of the zoom lens assembly is adjusted via a lever, and the compensating lens assembly is driven by the regularly rotating spiral grooves on the spiral sleeve. This, combined with the rotation of the lever and the outer casing, enables rapid and accurate image adjustment.
It enables rapid and accurate adjustment to produce clear images, reduces manufacturing difficulty and cost, and improves imaging stability.
