Konica Minolta CM-3700A Spectrophotometer

Konica Minolta CM-3700A Spectrophotometer

The Konica Minolta CM-3700A is a flagship benchtop spectrophotometer, renowned for its ability to deliver exceptionally accurate and reliable measurement results. Engineered with flexible aperture selections, an advanced optical design, and a large-diameter integrating sphere, this instrument easily satisfies and exceeds stringent international standards. The implementation of a high-performance pulsed Xenon flash during measurement ensures optimal precision.

Users are granted the operational flexibility to switch the measurement area using standard aperture selections of 25.4mm, 8mm, and 3x5mm, catering to the specific needs of each application. The Konica Minolta CM-3700A also comes equipped with a sample holder featuring an extended arm, enabling precise measurements at the center of specimens up to A4 dimensions, while a specialized damper mechanism prevents sample damage caused by accidental forceful closures.
