Which of the following tools is not used for blending peripheral curves in an office?

The slot gauge is not typically utilized for blending peripheral curves in an office setting. Instead, it is primarily designed for assessing the thickness of lenses or measuring the profile of a lens. Blending peripheral curves involves assessing the specific contour and transitions between different radii on a lens, and this task requires tools that are capable of providing precise measurements and visualizations of curves.

The radiuscope is particularly important in this context as it allows practitioners to measure the radii of curvature, which is essential in determining how well the curves are blended for optimal lens performance. The caliper, similar to the radiuscope, is useful for measuring thickness and can be applied in evaluating the curves on the lens. The lensometer, on the other hand, is utilized for verifying the prescription of lenses rather than directly measuring or blending curves, but it does play a role in the overall fitting and verification process.

In summary, tools like the radiuscope and caliper are essential for measuring and blending curves, and while the lensometer is critical for prescription verification, the slot gauge does not serve the function needed for blending peripheral curves effectively.
