OpTiSurf – Optical Roughness

Product Name: OpTiSurf
Product Code: LFA06
Test Material: Paper, Tissue, Board
Manufacturer: OpTest Equipment Inc.
Availability: Worldwide

Specifications:

• Advanced optics and algorithms for rapid quantification of optical roughness
• More objective than air-leak or stylus methods
• Correlates with traditional air-leak methods but offers greater precision and speed
• Provides a Roughness Index (ORI) and roughness values at different scales
• Non-contact measurement, applicable to various types of paper
• Accepts cut sheets or strips up to 30 cm wide
• Optical resolution of 125 µm/pixel
• Roughness (ORI) calibrated to 0.01 µm/field
• Fast measurement process (< 1 second/field)

Advantages:

• Faster and more precise than air-leak or stylus methods
• Minimal maintenance requirements
• Optical Roughness Index (ORI) correlates with air-leak methods
• Roughness intensities (FFT) over a size range from 0.25 mm to 32 mm
• MD and CD values
• Image storage and retrieval, Excel™ ready data and print-outs

Results:

• The ORI is reported in µm, measurable in machine (MD) and cross machine (CD) directions
• Optional FFT analysis module determines roughness intensity at 7 scales
• Reports available in various formats, including XML

Dimensions:
