Rez Checker Charts
The Rez Checker is a professional grade miniaturized target for assessing color, tone and white balance.
At center are 12 spectrally neutral gray patches for assessing correct exposure and white balance. The slanted edges can be used to reliably measure SFR or MTF out to 3000 dotperinch or 60 cy/mm with the appropriate software. Five line visual hyperbolic wedges are also included to aid in visual assessment of limiting resolution to 850 dpi.
The patches are mounted on aircraft grade anodized aluminum and are set below the top surface to help protect from damage.
Available Size: Height: 17/8” Width: 15/8” Thickness: 0.060” inches (47.625 x 41.275 x1.524 mm)
Gloss: Gray patches have an extended dynamic range (density ~ 2.4) and are suitable for measuring camera imager noise. Specular reflections from the gloss surface may occur for illumination geometries less than 45°/0° when used without crossed polarizers.
Matte: Gray patches have a lower dynamic range (density ~ 1.6) but are more suited to narrow illumination geometries such as those used in endoscopic imaging or with direct oncamera flash units. Because the matte surface can be interpreted as imager noise, we do not recommend using matte gray patch targets for evaluating imager noise in high magnification applications.
