Total Thickness Variation

Measure and analyze (absolute) thickness, thickness variation (TTV, LTV) and compare top to bottom surface of your products and samples.

Thickness one or double-sided

Measure and analyze thickness with single-sided systems for materials like glass or silicon or use our double-sided systems for comprehensive analysis on almost all materials.

Thickness Analysis

3D Thickness (TTV / LTV)

Measure your samples in 3D of sizes up to 600 x 600 mm² to analyze absolute thickness (average, maximum, minimum) and thickness variations (TTV, LTV) down to sub-micron accuracy.

2D Thickness

Perform fast 2D TTV measurements enabling you to analyze both the thickness (blue profile) as well as the detailed structure of the top (red profile) and bottom (green profile) surfaces in a single scan.

Positions (top to bottom surface)

Accurately verify the positions of features and structures with automated feature detection on both the top and bottom sides of your product, capturing alignment and orientation in a single scan. Use automated programs with ASCAN to confirm that any offsets remain within specified tolerances.

Non-Contact Thickness Measurement

The CT-system offer versatile thickness measurement capabilities, providing options for single-sided or double-sided measurements that include detailed data from both the top and bottom surfaces. 

Examples

Our metrology systems are designed to measure thickness across a diverse range of products and samples.

Other Applications

Measure R-parameters (e.g. Ra, Rz) in 2D or S-parameters (e.g. Sq, Smax) in 3D.

Measure the thickness of transparent layers or the top surface.
