This is a professional grade miniaturized target for assessing color, tone, and white balance in addition to measuring resolution and Spatial Frequency Response (SFR) or Modulation Transfer Function ( MTF) for digital cameras/scanners using edge gradient analysis of ISO 12233 and ISO 16067. All target patches are made in cooperation with Munsell Color Services from the same pigmented color paints as the GretagMacbeth™ ColorChecker®. At center are 12 spectrally neutral gray patches for assessing correct exposure and white balance. (These are NOT ink-jet, photographic, or electro-photographic generated colorants)

The slanted edges can be used to reliably measure SFR or MTF out to 3000 dot-per-inch 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. Patch sizes are 1/4" x 1/4". The overall size is 1-7/8" high x 1-5/8" wide x 0.060" thick and are available with either gloss or matte center gray patches. All colored patches on the perimeter are matte finish. Because these targets are hand cut and assembled, very minor patch mis-alignments may occur. They do not affect the target's utility.

Gloss Gray Patches

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

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 on-camera 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.

Matte with AR Coated Glass

This matte set is available with AR coated optical grade quartz cover glass and are useful in harsh, wet imaging applications. Each has been tested to be water and alcohol proof in submersible environments.

NIST traceable calibrations and certificate are available for the color and gray patches of the Micro Color ColorGauge target at an additional cost.
