Polyvar 2 magnification changer turret

Product Description

Reichert Polyvar 2 Magnification Changer Turret (Intermediate Optovar Module)

This is a magnification changer turret (often called an “Optovar”) from a Reichert Polyvar 2 research microscope. This precision optical-mechanical module provides selectable intermediate magnification factors—typically 0.8x, 1x, 1.25x, and 2x—allowing fine adjustment of total magnification and field of view without changing objectives. Sold AS IS for parts, restoration, or integration into a compatible Polyvar 2 microscope system.

Key Features:

• Magnification Settings: Four-position turret with standard settings: 0.8x, 1x, 1.25x, and 2x

• Design: Internal lens groups mounted in a robust rotating turret; includes external selector knob/dress

• Mounting: Designed to install between the microscope body and the observation tube/head of a Polyvar 2

• Optical Path: May include slots or ports for DIC (Differential Interference Contrast) prisms or other contrast accessories

• Compatibility: Specific to Reichert Polyvar 2 microscopes (may fit earlier Polyvar models but verification is essential)

Potential Uses:

• Polyvar 2 Microscope Restoration: Critical replacement part for completing a functional Polyvar 2 system.

• Component Salvage: Harvest precision lenses, prisms, ball bearings, detent mechanisms, and the finely machined turret housing.

• Custom Optical Projects: Repurpose as a variable magnification module for macro photography, telescopic eyepiece project, or custom imaging system.

• Historical/Collector Item: For enthusiasts of classic Austrian (Reichert/Vienna) research microscopes.

Important Notes:

• Compatibility is Critical: This turret is designed specifically for the Reichert Polyvar 2 optical train and mounting footprint. It will not fit other microscope brands without significant modification.

• Optical Inspection Required: Internal lenses should be inspected by a specialist for cleanliness and coating condition before use.

• Mechanical Service Likely Needed: The rotating mechanism may require disassembly, cleaning, and re-greasing for smooth operation.
