Optimap surface analyzer

The unique solution for surface inspection enables rapid measurement and analysis of large areas of all types of coated or uncoated surfaces.

Powerful on-screen functionality includes cross-sectional visualization allowing detection and characterization of common surface irregularities, including flaws and ripple.

In quality control, inferior surface evaluation methods are still commonplace. Many methods lack definition, take time, and are subjective. Modern consumers demand high quality products with consistent surface finishes that are free from defects.

The use of Optimap2 provides a unique solution to these measurement challenges by providing quantifiable data for better production control.

Surface texture is used to quantify visible flaws such as orange peel, ripple, and DOI issues. It can also be used to identify local faults such as:

Orange peel :

Overspray

Inclusions

Blisters

Drips

In one quick operation, the Optimap ™ 2 maps the topography of a test surface displaying defects and texture in incredible detail. The mapped information is processed into objective surface measurements which can be used to effectively control product quality. This product can be compared to the Wavescan DOI.

How it works?

The Optimap 2 can run on battery or mains and is suitable for laboratory or factory use. It operates through an intuitive touchscreen and has an integrated file system that allows measurements to be stored in an organized structure.

The Optimap 2 can measure most surfaces, from ultra matte to mirror finish.

When a measurement is initiated, an internal target screen displays a series of optical fringes. These fringes are reflected in the surface of the sample and captured by a camera. Typical acquisition time is

Using a technique called PHASE step deflectometry, the instrument creates a 3D map of the sample surface. Typical computing time is

The scale of the map is (m-1 curvatures). The curvature map represents an exaggerated view of how the eye perceives surface quality and defects

The results can be filtered to simulate different viewing distances from:

Ta: high frequency texture visible at less than 1 m up to Te: ripple visible at 3 m from the surface.

Results can be displayed as a texture compatible with other ripple or curvature measuring instruments, an m-1 traceable measurement

Maps can be enlarged and paned to show high resolution defects. The recorded results can be transmitted to the software for further analysis.

Characteristics

• Robust and precise, the Optimap ™ 2 is suitable for laboratory, factory or on-site inspections.
• The soft touch measurement portal means the instrument can be used safely on the highest quality surfaces.
• No movement required during measurement
• Texture and surface defects can be assessed on a wide variety of surfaces: semi-matt surfaces to polished mirrors, small parts and curved parts
• A large area is mapped in a single run (79mm x 57mm), up to 100 times more representative than other texture analysis instruments
• A variety of regions of different shapes can be actively created on the screen image, making it possible to include or exclude areas inside or outside the region.
• This advanced functionality is useful for surfaces with complex shapes where areas fall outside the field of view of the instrument.
• Once a region has been created and confirmed, the measurement results
• adjust to the new dimensions of the image. Regions can be resized and moved
• to allow the selection of a region of interest or deleted by completely restoring
• the original image.
• On-screen texture maps show orange peel, ripple, and surface flaws in incredible detail
• Objective measurements can be displayed in traceable SI units or selected industry scales

• Data and results are fully compatible with other analytical techniques and third-party software
• Optional software enables sophisticated texture / defect analysis and reporting

Ondulo reading software

Rhopoint Ondulo reader software offers advanced data analysis and reporting.

Surface effects such as texture, flatness, number, size and shape of local defects can be identified, mapped and quantified

Curvature profile

Curvature, slope or altitude profiles can be characterized

3d view
