Description
Spectrophotometer CM-26d / CM-25d
The Konica Minolta Spectrophotometer CM-26d and Spectrophotometer CM-25d, with d:8° geometry and horizontal alignment, are designed for color measurement of various samples such as automotive interior parts and trims, small plastic parts, electronic devices, ceramics, and more. These spectrophotometers provide high accuracy and repeatability for consistent digital color data management within a supply chain.
The Konica Minolta Spectrophotometer CM-26d and CM-25d deliver a specialized, high-precision solution for digital color data management across global supply chains. Quality assurance managers and automotive technicians utilize these horizontal-style instruments to validate the color of interior trims, small plastic parts, and electronic enclosures with absolute accuracy. This specific series addresses the unique requirement of maintaining consistent color standards between different manufacturing facilities. Consequently, your facility gains the ability to eliminate visual inspection errors and reduce production waste through reliable spectral data.
Instead of relying on uncalibrated color readers that struggle with tight tolerances, your team achieves a technical advantage with the Konica Minolta CM-26d. The system provides a market-leading inter-instrument agreement (IIA) that ensures your measurements match those of your partners and customers worldwide. Therefore, you can confidently share digital color standards and perform pass/fail judgments without the need for physical master samples.
Konica Minolta CM-26d Technical Advantages
This portable spectrophotometer packs advanced features for demanding industrial and R&D environments. It features an integrated viewfinder that allows technicians to position the instrument precisely on small or patterned samples. This visual guidance ensures that your engineering team captures exact color data from specific regions of interest without the risk of measurement overlap. Furthermore, the unit delivers switchable measurement areas between MAV (Ø8mm) and SAV (Ø3mm) to accommodate various part sizes within a single inspection cycle.
The CM-26d also features a high-resolution 2.7-inch color TFT display that provides real-time spectral graphs and pseudocolor indicators. Technicians can toggle between SCI (Specular Component Included) and SCE (Specular Component Excluded) modes to analyze both true color and surface appearance simultaneously. Additionally, the unit supports the Configuration Tool CM-CT1 software, which allows users to synchronize settings across multiple instruments effortlessly.
