Map and measure surface finish with the the Rhopoint Optimap-PSD. Characterisation of common surface irregularities including defects and waviness.
The unique solution for surface inspection allows rapid large area measurement and analysis of all types of coated or uncoated surfaces.
Powerful on-screen functionality includes cross-sectional viewing allowing detection and characterisation of common surface irregularities including defects and waviness.
In quality control, inferior surface evaluation methods are still commonplace. Many methods lack deﬁnition, are time consuming and subjective. Modern consumers demand high quality products with surface ﬁnishes that are homogenous and free from defects.
The use of Optimap2 provides a unique solution to these measurementchallenges providing quantiﬁable data for improved production control.
Surface texture is used to quantify visible faults such as orange peel, waviness and DOI problems. It can also be used to identify local faults such as:
In a single fast operation the Optimap™ 2 maps the topography of a test surface displaying faults and texture in incredible detail. Mapped information is processed into objective surface measurements that can be used to effectively control product quality. This product can be compared to the Wavescan DOI.
How does it work?
- The Optimap 2 can be battery or mains operated and is suitable for use in the laboratory or on the factory floor. It is operated by an intuitive touch screen operation and has a built in file system that allows measurements to be stored in an organized structure.
- The Optimap 2 can measure most surfaces from ultra matt to mirror finish.
- When a measurement is initiated, an internal target screen displays a series of optical fringes. These fringes are reflected in the sample surface and captured by a camera. The typical acquisition time is < 3 seconds.
- Using a technique called PHASE stepped deflectometry the instrument builds a 3D map of the sample surface. The typical calculation time is < 5 seconds.
- The scale of the map is (curvatures m-1). The curvature map represents an exaggerated view of how the eye sees surface quality and defects
- The results can be filtered to simulate different viewing distances from:
Ta: High frequency texture which is visible from less than 1m up to Te: Waviness visible from 3m away from the surface.
- Results can be shown as texture which is compatible with other waviness measuring instruments or curvatures, a traceable measurement m-1
- The maps can be zoomed in and panned to view defects in high resolution. Stored results can be output to software for further analysis.
- Rugged and accurate the Optimap™ 2 is suitable for laboratory, factory or on-site inspection.
- The soft touch measurement portal means the instrument can be used safely on the highest quality surfaces.
- No movement required during measurement
- Surface texture and defects can be assessed on a huge variety of surfaces: semi matt surfaces to polished mirrors, small & curved parts
- A large area is mapped in a single operation (79mm x 57mm), up to 100 times more representative than other texture scan instruments
- A variety of diﬀerent shaped regions can be created actively on the screen image allowing areas inside or outside the region to be included or excluded.
This advanced functionality is useful for surfaces with complex shapes where areas fall outside the instruments ﬁeld of view of measurement.
Once a region has been created and conﬁrmed, measurement results
adjust to the new image dimensions. Regions can be resized and moved
to allow selection of a region of interest or deleted completely restoring
the original image.
- Onscreen texture maps show orange peel, waviness and surface defects in incredible detail
- Objective measurements can be displayed in traceable SI units or selected industrial scales
- Data and results are fully compatible with other analytical techniques and third party software
- Optional software allows sophisticated texture/fault analysis and report generation
