A few specialty glues set up and harden quickly when exposed to ultraviolet light. They're good for attaching hinges to glass. December 2, 2006.

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.

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.

Nano Target: Patch sizes are 1/8” x 1/8”. The overall size is 1.0” high x 7/8” wide x 0.060” thick and are available with either gloss or matte center gray patches.

Micro Target: 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.

Batch Colorimetric information data for the patches can be found at Micro/Nano/Pico Colorimetry Data. NIST traceable calibrations and certificate are available for the color and gray patches of individual Rez Checker Micro targets at additional cost. (NIST certification is not available on Rez Checker Nano targets.)

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.

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.
