Spectrophotometer CM-36d


The Spectrophotometer CM-36d is a benchtop spectrophotometer for reflectance color measurement with advanced functions that provide cost-effective solutions to today’s measurement needs. This model is well-suited for a wide range of applications in various industries such as plastics, paints, ceramics, chemicals, etc.

With an inter-instrument agreement (IIA) of ΔE*ab< 0.15 and repeatability of σ∆E*ab < 0.03, the CM-36d can assure the measurement data communicated within the supply chain is very consistent. The CM-36d is designed with enhanced usability. The instrument comes with a flat-back design that allows its orientation to be repositioned to take measurements vertically (top-port concept). The front plate of the CM-36d comes with four screw holes that enable easy installation of custom adapters/sample holders. It also has three different aperture sizes (Ø 4.0 mm, 8.0 mm, and 25.4 mm) for different measurement needs.

With an easy-to-read status panel including a measuring button, the CM-36d can display the measurement status and condition settings at a glance, reduces operator error and improves work efficiency. Accurate positioning of the measurement sample is made easy with its sample viewing function that utilizes an integrated camera to provide a clear preview of the sample.

The CM-36d offers stable and reliable measurement data over time through its optional WAA (Wavelength Analysis & Adjustment), an innovative function that analyzes and adjusts for any wavelength shift during each calibration.

Efficient 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

The 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-36d 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

Accurate 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.

Easy to read LED indicator panel with measurement button

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-36d 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.
