DS-36D/37D/39D Benchtop spectrophotometer
Dual optical path design based on differential spectrum engine and nanoscale grating
Color spectrum benchtop spectrophotometer DS-36D series adopts self-developed differential spectrum engine to increase light intake by 50% and spectral resolution by 30%.
Provide better repeatability, inter-station difference, display performance; The clarity of the camera is increased by 350%, and the color of ultra-dark samples can be truly
restored through the self-developed brightness calibration algorithm. The powerful ColorExpert computer data management software supports the simultaneous saving
of sample data and images. DS-36D series products will play a more outstanding role in quality control management and color matching in various industries such as paint,
plastics and textiles.

Differential spectrum engine improves overall measurement performance
The light input of the sensor is increased by 50%, thespectral resolution is increased by 30%, the signal-to-noiseratio is higher, the repeatability, the difference between theinstrument, and the data is highly consistent with the dataof the standard instrument, the inter-instrument agreement can reach to 0.08, and the repeatability can reach to 0.005. The relevant technologies are protected byChinese invention patents
Double optical path design improves repeatability accuracydE*ab≤0.005
The dual optical path design monitors the energy fluctuation ofthe light source while measuring the sample signal, reducesinterference during measurement, obtains higher measurementstability, and improves the measurement repeatability index ofthe instrument to dE*ab ≤ 0.005. The high standard ofmeasurement speed, accuracy, stability and inter-stationdifference is guaranteed. The relevant technologies areprotected by Chinese invention patents and American inventionpatents
Innovative 1nm resolution grating spectroscopy technology
After nearly 10 years ofdedicated research, the grating combined array sensor made bythe innovative MEMS process makes the color measurementmore accurate on the basis of 1nm spectral resolution, onceagain leading the industry innovation direction and greatlyimproving the technical performance of the product. Therelevant technologies are protected by Chinese inventionpatents.
Excellent inter-instrument agreement：dE*ab≤0.08，High repeatability accuracy：dE*ab≤0.005，ensure accurate data transfer between factories
Self-developedfluorescencecalibration technique
Automatically adjust the UV intensity,and ensure that the instrument value is highly consistent with the reference value when measuring the fluorescent material.
High precision automatic calibration
Advanced automatic calibration technology greatly improves long-term repeatability of instruments. Under constant temperature, the dE*ab of day 1 and day 30 can still reach 0.01. At any temperature change from 0℃ to 40℃, dE*ab can reach less than 0.1.
Easily measure samples of many shapes with a variety of measuring apertures
Four test calibers, free to switch
Support measurement in reflection mode: solid, powder, non-transparent liquid
Support measurement in transmission mode: glass, film, transparent liquid
Configure high-definition preview camera
The clarity of the camera has been significantly upgraded, from the original 400dpi to 1400dpi.When observing the sample, the clarity hasbeen improved by 350% and brightness calibration algorithm has been used to truly restore the color of the ultra dark sample.
