Qualsiasi obiettivo per visione artificiale (telecentrico o meno) mostra una certa distorsione. Oltre alle tipiche distorsioni a barilotto ed a cuscinetto, lievi variazioni nell’angolo di osservazione o un allineamento impreciso dei componenti ottici si ripercuoterà sulla simmetria del sistema, generando distorsioni prismatiche o trapezoidali.

La maggior parte delle applicazioni di imaging e metrologia richiedono di minimizzare la distorsione, che può essere corretta via software analizzando l’immagine di un pattern di precisione con caratteristiche geometriche note.

A questo scopo, Opto Engineering offre pattern cromo-su-vetro ad altissima precisione prodotti con tecniche fotolitografiche. La nostra gamma di pattern a scacchiera ha caratteristiche geometriche ottimizzate per la calibrazione via software dei obiettivi bi-telecentrici ed è ampiamente compatibili con la maggior parte delle ottiche disponibili.

Le scacchiere sono realizzate con due diversi processi al fine di fornire la migliore soluzione a seconda delle esigenze:

Cromata su vetro, per applicazioni all'avanguardia;
Pellicola su vetro, per una perfetta sintesi di prestazioni ed economicità.

Inoltre, è disponibile una versione certificata: gli standard e le apparecchiature utilizzate per la calibrazione sono stati calibrati e tracciati al National Institute of Standards and Technology (NIST), in conformità con le procedure stabilite in ISO / IEC 17025-2005 e ANSI / NCSL Z540-1 -1994.

It’s possible to calculate dimensional tolerance of pattern’s features is calculated as follows:

Dimensional Tolerance = ± (A + B * C)

A = Positioning error

B = Speed factor

C = Dimension of interest

Example of dimensional tolerance for grade 2 pattern over 10mm length:

Dimensional Tolerance = ± 0.0016mm + (±0.000008mm x 10 mm) = ± 0.00168 mm

For Glass Photomask
Class	Min feature dimensions; Min spacing(µm)	Positioning error (µm)	Speed factor (µm/mm)
1	1.4	6.4	0.016
2	0.8	1.6	0.008
3	0.4	0.6	0.004
4	0.2	0.2	0.001

For Film Photomask
Grade	Min feature dimensions; Min spacing(µm)	Positioning error (µm)	Speed factor (µm/mm)
1	9.6	10	0.005
2	4.8	10	0.005
3	2.4	10	0.005
4	1.2	10	0.005
