Measuring method(Use) | Transmittance(plastic films and others)and reflectance (coatings,paintings,colored aluminum,paper,films for LCD,and others) |
Values to be measured | Image clarity C%,maximum reflectance(transmittance)M,minimum reflectance(transmittance)m |
Measuring angles | Transmittance:0°incidence and viewing of transmitted light Reflectance:45°incidence and viewing,or 60°incidence and viewing (Either of the angles can be selected by switching.) |
Slit | 0.03mm(JIS K 7105,JIS K 7374)or 0.1mm(JIS H 8686-2), Either to be selected upon request |
Aperture | Ф25mm |
Optical comb width | 0.125mm,0.25mm,0.5mm,1.0mm,and 2.0mm |
Allowance | Within 0.2% standard deviation of C (subject to the light passing the 0.125-mm wide optical comb and transmitted through air) |
