3nh TS-26C spectrophotometer is an enhanced laboratory-grade spectrophotometer independently developed by 3nh, specifically designed for high-precision color analysis and transmission scenarios. It adopts the internationally recognized 45/0 optical structure and incorporates a high-performance optical system, achieving rapid and accurate measurements within the 400–700nm spectral range. The product is equipped with seven measurement apertures to flexibly adapt to samples of different sizes and shapes, and has the capability to measure fluorescent samples. It also meets the requirements for measuring the luminance factor and chromaticity coordinates of traffic signs, markings, and reflective films. It includes GB 2893 and GB/T 18833 standard colors and supports manually customized polygonal rectangle tolerances, providing professional solutions for color management across various industries.
Optical geometry: The 45/0 illumination method (45° circular uniform illumination, 0° reception) is adopted, which complies with standards such as CIE No.15, GB/T 3978, and GB 2893 to ensure measurement standardization and data consistency.
Combined full-spectrum LED light source: It employs a combination of 400-700nm full-spectrum LED light source and UV light source, ensuring sufficient spectral distribution within the visible light range, avoiding spectral loss in specific wavelengths, preventing saturation under strong light, enhancing sensitivity under weak light, and allowing for easy measurement of fluorescent samples.
Silicon photodiode dual array (40 groups) sensor: Using larger area silicon photodiode array (40 groups in two rows) sensor effectively solves the problems of strong light saturation and weak light detection, ensuring the instrument's measurement speed and accuracy.
Repeatability accuracy：Within ΔE*ab 0.018，The repeatability accuracy of the instrument has reached a level that is difficult for similar products to match.
Inter-instrument Error: Within ΔE*ab 0.15，Ensure the measurement results from multiple devices are highly consistent.
It supports the measurement of luminance factor and chromaticity coordinates of traffic signs, markings, and reflective films, and is adapted to the strict requirements of the transportation industry for the consistency of road sign colors.
Built-in GB 2893 (safety colors) and GB/T 18833 (road traffic reflective film) standard colors, no need for additional import, and can manually customize polygonal rectangle tolerances to improve industry application efficiency.
Provides seven measuring apertures (12mm、11mm、10mm、6mm、5mm、3mm、1*3mm platform)，It can be flexibly switched according to the sample size (such as small electronic components or large road signs) to adapt to diverse measurement scenarios.
Configure 10 color spaces: including CIE LAB、XYZ、Yxy、LCh、CIE LUV、s-RGB etc. It meets the color definition and analysis needs of different industries.
Supports 9 color difference formulas: including ΔEab、ΔEuv、ΔE94、ΔEcmc (2:1)、ΔE*00 etc, it can accurately quantify color differences and adapt to color difference judgment standards in different scenarios.
Rich colorimetric index: It supports measurements such as whiteness (WI), yellowness (YI), metamerism index (MI), blackness, and color density (CMYK), as well as staining fastness, color change fastness, force content, and opacity, covering the entire color evaluation process.
Supports observation of 41 light sources: including （D65、A、C、D50 etc，some are achieved through PC software）and 2°/10° view angle，It can simulate visual effects under different environments and meet the needs of color transmission across different scenarios.
Convenient operation: Equipped with a 3.5-inch TFT true-color capacitive touchscreen, it can intuitively display spectrum/data, colorimetric values, color difference values/comparison charts, and pass/fail judgment results, making it easy to operate.
USB + Bluetooth dual interface：Support USB +Bluetooth，It can connect to computers and printers, and is compatible with Android/iOS/Windows systems and WeChat mini programs, making data transmission and report generation more flexible.
High measurement efficiency：A single measurement takes only about 1 second, and it supports the storage of 1,000 standard samples and 30,000 test samples, meeting the long-term data traceability needs of a large number of samples.
