Profile Projector (Optical Comparator)
Digital Profile Projector (also called an Optical Comparator) is a non-contact inspection system that magnifies a part’s silhouette on a screen for fast 2D measurement. This category includes both Digital Vertical Profile Projector and Digital Horizontal Profile Projector platforms, covering routine QC checks and higher-throughput inspection where clear edge visibility and repeatable measurement matter.
Digital projection helps you measure profiles, radii, angles, distances, and feature locations without contacting delicate parts. Adjustable contour and surface illumination improves contrast across different finishes, while digital readout workflows support consistent reporting.
Product types in this category
1. Vertical Profile Projector (Optical Comparator)
Vertical projectors are a practical choice for general profile inspection and daily dimensional checks. They support stable focusing and consistent setup for small-to-medium parts, fixtures, and routine measurement work.
Included series
- QualiPP™ V300 Series (Ø300 class)
- QualiPP™ V400 Series (Ø400 class)
2. Horizontal Profile Projector (Optical Comparator)
Horizontal projectors are commonly used when a horizontal optical path and stage layout improves part handling, edge viewing, or fixture setup. They support profile inspection on machined, stamped, and molded parts where repeatability and speed are priorities.
Included series
- QualiPP™ H300 Series
- QualiPP™ H400 Series
- QualiPP™ H3015 (digital horizontal video projector workflow)
Why choose Digital Profile Projectors in Production QC
Digital projection supports faster inspections, reduces part contact risk, and helps standardize operator workflows. When paired with stable mechanics and controlled illumination, an Optical Comparator becomes a dependable tool for repeatable 2D measurement across shifts and lots.
