Low Magnification Calibration Standards and Color Calibration Slides
Available for SEM and LM
Silicon Test Specimen
This Test Specimen is made of a 5mmx5mm square of single crystal silicon. It is photo-etched and the squares repeat every 10µm. The dividing lines are 1.9µm wide.
A broader etching line is written every 500µm, which is useful in light microscopy. This is an excellent test specimen for comparing magnification and assessing any distortion in the image field. It is ideally useful in the context of automated counting systems to check for unsuspected distortions. Where critical measurements must be made the sample can be mounted directly onto the calibration specimen so that an internal calibration is obtained on the micro-graph.

NIST Traceable Color Transmission Calibration Slide - Calibrated
Microscopy color patches for assessing color accuracy. NIST traceable calibration data for each large color patch is supplied as spectral transmission. By using the supplied spreadsheet, this data can be converted to the color space you need (such as Adobe RGB 1998, L*A*B*, XYZ, etc.)
-24 color patches plus large clear area
-Black background to minimize flare
-The 4150 µm diameter patches are individually calibrated for spectral transmission. This allows accurate conversion (using the supplied spreadsheet) to other color space units.
-Smaller patches from 1000 µm diameter to 150 µm diameter are exposed and processed at the same time produce good correlation of the large calibrated patches to the smaller ones, but are not calibrated.
-Oil immersion objectives can be used because a standard 0.15 mm glass cover slip is permanently cemented over the color film.
-Film is permanently sandwiched between glass; atmospheric deterioration of the measured values is minimized.
-Each slide is individually serialized and calibrated.
Specifications
| Overall Size | 75mm x 25mm |
| Feature Array | 24 unique color patches in 9 different sizes, ranging from 4.150 mm diameter to 0.150 mm diameter, and a large clear film area. Only the large patches (and clear area) are directly calibrated, but all patches are imaged and processed at the same time. |
| Polarity | Negative |
| Material | 0.2 mm (0.007") thick polyester photo-film mounted onto 0.9 to 1 mm water white Soda-lime Glass with a 0.15 mm (0.006") glass coverslip for protection (exact thickness is subject to change) |
