Il filtraggio della luce è una necessità tipica delle applicazioni di visione artificiale. Insieme agli illuminatori LED, i filtri possono migliorare il contrasto dell'immagine bloccando la luce indesiderata e aumentando la precisione e la ripetibilità del sistema di visione.
La luce dell’ambiente è molto spesso causa errori nei sistemi di imaging, dovuti a riflessi indesiderati provenienti dalla superficie degli ogetti da misurare. In questi casi, un filtro passa banda o a passo lungo corrispondente alla lunghezza d'onda di emissione dell'illuminatore viene generalmente integrato di fronte all’obiettivo di imaging: in questo modo, solo la luce proveniente dall'illuminatore viene raccolta mentre il resto dello spettro viene tagliato.
Inoltre, molte applicazioni di visione artificiale richiedono un’illuminazione monocromatica per migliorare o eliminare particolari caratteristiche dell'oggetto: in queste condizioni, infatti, solo le caratteristiche con un certo colore vengono esposte e controllate.

PCB Inspection: The layout of the printed circuit would be difficult to distinguish without the filter. A high transmission green band pass filter increases contrast and improves system accuracy.

Note
- Tolleranza +/- 10 nm
Note aggiuntive
- Eccetto per TC23004, TC23007, TC23009 e TC23012. Può presentare vignettamento quando usato con altri obiettivi telecentrici, a seconda della dimensione del sensore.
