Vertical Profile Projector (Optical Comparator) Category – QualiPP™ V-Series

Profile Projector (also called an Optical Comparator) is a non-contact measuring system that projects a magnified part silhouette onto a screen for fast 2D inspection. This category covers the QualiPP™ V-Series vertical Profile Projector / Optical Comparator lineup, designed for repeatable measurement of profiles, radii, angles, distances, and feature locations in production QC and metrology labs.

Both series use a QualiDigi™ Readout 400 digital readout workflow, LED contour and surface illumination, and objective lens options to match different part sizes and inspection detail requirements.

Common Applications for a Profile Projector / Optical Comparator

Fast profile inspection for machined and stamped parts - Measure outlines, radii, chamfers, step features, and hole-to-hole spacing using projected edges for quick pass/fail decisions.
Tooling, dies, and maintenance checks - Confirm tool angles and profile geometry without contacting sharp edges or fragile features.
Plastics, rubber, and molded items - Inspect silhouettes and profile deviation on softer materials where contact measurement could deform the part.
Electronics and small precision assemblies - Support quick checks for brackets, connectors, and small components where consistent edge visibility helps reduce re-checks.

Product Lineup

1. Digital Vertical Profile Projector (Optical Comparator) – QualiPP™ V300 Series

A Ø300 mm class system designed for compact inspection setups and routine 2D measurement tasks. It supports QualiDigi™ Readout 400 readout workflows, adjustable contour and surface illumination, and objective lens options for daily QC.

How to Choose the Right model

Choose QualiPP™ V300 Series when your parts fit a Ø300 mm class viewing range and you want a smaller footprint for routine inspection. Choose QualiPP™ V400 Series when you need a larger screen class, larger travel options, or more comfortable coverage for bigger parts and fixtures.

Why choose QualiPP™ V-Series

Stable vertical motion supports consistent focus and repeatable inspection work.
Adjustable contour and surface illumination helps tune contrast across different materials and finishes.
High-resolution optics support clear projected edges with low magnification error (as specified in the brochures).
QualiDigi™ Readout 400 supports fast 2D measurement and practical documentation.
