Fixed, Dual-Reference Measurement for Dental and Ophthalmic Workflows

The Thornstein fixed caliper is a compact measuring instrument designed to help professionals assess defined distances during dental and ophthalmic workflows. Its 3 1/8-inch overall dimension supports controlled handling in the working area, while the product is identified for two application references: 3.0 mm aphakic and 4.0 mm phakic. This fixed configuration provides a straightforward way to select the relevant measurement without adjusting a sliding mechanism during the task. The focused design can support consistent dimensional assessment where a dedicated caliper is appropriate, helping keep measurement steps clear and efficient within established clinical procedures.

Use Cases

Assess a 3.0 mm reference in aphakic ophthalmic workflows.
Assess a 4.0 mm reference in phakic ophthalmic workflows.
Support dimensional assessment during dental procedures or laboratory workflows where a fixed caliper is appropriate.
Use the dedicated fixed configuration when a defined measurement reference is preferred over an adjustable instrument.
Bring a compact 3 1/8-inch caliper into workflows requiring controlled access and direct dimensional checking.

Specifications

Care & Handling

Clean the caliper according to facility procedures and the applicable instructions for use.
Inspect the fixed measuring areas and frame for visible residue, damage, or distortion before handling.
Handle the instrument carefully to preserve the alignment of its fixed measurement points.
Store it clean, dry, and protected from impact or contact with instruments that could damage the measuring surfaces.
