MAINTAINING YOUR SPECTROPHOTOMETER
Cleaning the Calibration Tiles
Ceramic standards (calibration tiles) are widely used in color science as standards of reflectance
factor. Their principal virtue is the stability of their reflection properties. If they are to serve their
intended purpose, it is necessary that the surfaces of these tiles be maintained in a stable
condition. The cleaning of any precision optic risks degrading the surface. Therefore, the need for
cleaning should be minimized by returning the tile to its storage case or covering it with a
protective bag when it is not in use. If cleaning is required, the following procedure is
recommended.
Materials Required
Camel's-Hair Brush: Available at most camera, hardware, or art supply stores.
Dust free tissue: Use a lens tissue, which meets Federal Specification NNN-P-40A, Type I or
equivalent.
To remove dust, lint, and invisible gritty particles, proceed as follows:
1.
Lint and other small particles are usually best observed by illuminating the tile with a diffuse
light source at an angle so that the light does not produce surface glare. Inspect the tile at an
angle rather than looking directly at the tile’s front surface.
2.
Brush the tile's surface with a camel's-hair brush.
3.
Breathe a light mist of condensed vapor at the center of the tile.
4.
Immediately wipe the tile's surface lightly with lens tissue. Avoid smearing the tile with
natural greases and perspiration from the hands by wiping with the untouched center part of
the lens tissue.
Cleaning the Black Plastic Blocking Panel
Dust on the black plastic blocking panel can be very tightly bound by static electricity. To remove
the dust, blow canned air across the surface.
Cleaning the Black Trap
The black trap should be cleaned from time to time to remove and dust or contamination that
may collect inside.
1.
Remove the base (1) from the trap (2) by turning to the left and lifting upwards.
