|Overall Size:|| 2.0 in. x 2.0 in. |
(50.8mm x 50.8mm)
Frequency range from 1 c/mm to 500 c/mm; 100:1 or greater contrast; Bar width to length ratio 1:10; chrome image area on glass substrate. Progression is approximately 20%.
The bar pattern gives direct limit of cut-off resolution. Ideal for micro-densitometer scanning, hi-power optical systems, semi-conductor processing and CCD devices.
