Ultra-High Resolution Target (T-90)

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%. Positive polarity T-90 targets are available on Photo Paper (RM) and Film (TM), while the negative polarity is imaged on either Chrome on Glass (CG) or Chrome on Opal (OP).

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.
