Bright, Clear Sample Viewer for Accurate Sample Positioning Opening the sample viewer provides a clear, illuminated view of the sample at the measurement port. On the CM-3600A, this view is reflected in a mirror on the sample viewer cover so that you can view it easily even while seated.
Three Measurement Areas For Diverse Needs Masks for the CM-3600A’s three measurement areas (SAV: Ø4 mm, MAV: Ø8 mm, and LAV: Ø25.4 mm) are included as standard accessories, so you can select the one that fits your measurement requirements. Improved sample holder The sample holder opens approximately 90° for easy positioning of samples. It also has a new “soft-close” mechanism that prevents it from slamming shut and damaging samples or pinching fingers. Bright, clear sample viewer can be used even while seated. The sample viewer lets the sample be seen clearly at the measuring port for accurate positioning. When the sample viewer cover is opened, a high-brightness LED illuminates the sample to provide a clear image, and the cover is equipped with a mirror so that the image can be seen even from a seated position.
Numerical Gloss Control Provides Simultaneous SCI/SCE Measurements The CM-3600A utilizes Konica Minolta’s patented Numerical Gloss Control system, eliminating the need for a mechanical gloss trap. By firing two xenon lamps in quick succession, the system can provide virtually simultaneous SCI (specular component included)/SCE (specular component excluded) measurements and also enable the calculation of 8° gloss.
Numerical UV Control for Accurate Measurements of Fluorescent Materials Accurate measurement of materials such as paper or cloth treated with fluorescent whitening agents (FWA) requires precise control of the UV component and its effects. The patented Numerical UV Control method used by the CM-3600A can provide such control by using proprietary calculations to combine the results from flashes of two xenon lamps: one with full UV energy, the other with UV energy removed by a UV-cutoff filter (either 400 nm or 420 nm). This method eliminates the need for mechanical filter positioning and repeated filter position adjustment, and enables UV adjustment by Whiteness Index, Tint, Brightness, or UV profile.
