Spectrophotometer CM-36dG


High-precision spectrophotometer with an integrated ISO compliant gloss sensor and stability check

Introducing the industry’s first color and gloss bench-top spectrophotometer, the Spectrophotometer CM-36dG, with an integrated ISO 2813 compliant 60° gloss sensor inside to measure color and true gloss simultaneously. By measuring and reporting both values together, you can streamline your quality control workflow, reduce operator errors, and save on equipment and maintenance costs.

The Spectrophotometer CM-36dG is a high-precision and high-reliability bench-top instrument capable of measuring color either in reflectance or transmittance, ideally suited to a wide range of applications such as Plastics, Paints, Ceramics, Chemicals, etc.

The Spectrophotometer CM-36dG utilizes the patented and proven Numerical UV Control (NUVC), unsurpassed technology for UV adjustments when measuring samples that contain optical brighteners such as pulp, paper, textiles, or chemicals.

The Spectrophotometer CM-36dG includes several new features to improve the user experience. Status LEDs provide clear visual feedback, a camera preview system for sample positioning and reporting, and versatile port alignment allowing the device to be rotated 90° to measure powdery materials in “Top-port” style.

The optional Wavelength Analysis & Adjustment or WWA, a Konica Minolta Sensing innovation, compensates for slight shifts in measurement values due to external factors. It assures the highest accuracy and repeatability levels for this class of instrument when done together with annual calibration and maintenance.

The Spectrophotometer CM-36dG is compatible with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis, as well as Colibri software to formulate color recipes for various applications and share real-time measurement data.


Features

Efficient sample presentationEfficient sample presentation
Four screw threads and linear guidelines in the front plate enable the operator to create custom jigs to accurately position samples, maximizing the measurement process’s repeatability and speed.

Camera previewer for accurate sample positioning
Camera previewer for accurate sample positioningThe integrated camera viewer provides a clear preview of the sample for precise targeting and controls the measurement area. The software can capture images of the measurement area to provide detailed and concise reporting.

Reflectance and Transmittance measurements, horizontal or top-port
The Spectrophotometer CM-36dG can measure solid or liquid samples in reflectance or transmission mode, horizontally or in a vertical standing position; this offers great flexibility for measuring various samples ranging from opaque to translucent and transparent.

The large, open sided transmission chamber can measure transparent or translucent samples of any size with ease. The transmission chamber lid features a lift-and-turn lock to prevent accidental opening of the device. It locks the chamber when being used in a vertical standing position to measure powdery material in petri dishes.

Numerical UV Control for Accurate Measurements of Fluorescent Materials
Numerical UV Control for Accurate Measurements of Fluorescent MaterialsAccurate measurement of materials such as paper or cloth treated with optical brighteners (OBA) requires precise control of the UV component. The patented Numerical UV Control method (familiar to customers who used the Spectrophotometer CM-3600A) provides UV control by using proprietary calculations to combine the results from two xenon lamps’ flashes. 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 lengthy filter position adjustment processes and enables UV adjustment by Whiteness Index, Tint, Brightness, or UV profile.

The LED indicator panel displays current measurement settings at a glance. In addition, the measurement button in the panel allows measuring samples remotely.

Measurement Areas to match your samples
The Spectrophotometer CM-36dG offers four different apertures with Ø 4.0, 8.0, 16.0, and 25.4 mm to provide a suitable measurement size for any sample.

Optional “Wavelength Analysis & Adjustment” – (WAA)
“Analyze – Adjust – Activate” – Konica Minolta’s patented technology checks and adjusts possible wavelength shift during each instrument calibration. This procedure assures unsurpassed long-term measurement stability and can keep measurements stable even for changes in temperature or environmental conditions over time.

WAA allows the operator to distinguish whether the instrument itself is the cause of measurement differences, reducing troubleshooting time and providing improved certainty within supply chains.
