Chroma ™ Optical Spectral Analysis and Color Measurement Chroma™ Powerful software package for optical spectral analysis and color measurement Color is an important design and product recognition feature, one that can mean the difference between market success and failure. Particularly when using natural or recycled raw materials with varying compositions, continuous, objective monitoring of the effect of color is a key prerequisite for uniform quality. With the Chroma software package and a PC-controlled spectrophotometer, you can now determine the transmission and reflection properties of solids and liquids precisely, and on the basis of these calculate and graphically display color values according to both the Helmholtz and the CIELAB method. Chroma links measurement and evaluation with a powerful database in which all results are stored in an optimized structure. The Chroma software ensures the traceability and complete documentation of all measurements to actively support you in implementing your quality standards. Features > Directly controls spectrophotometers from a variety of manufacturers > Integrated color determination according to ISO 11664/CIE 15 > Graphic, interactive display of measurement results > Wide range of evaluation options > Integrated database with trend analysis > Special functions for measuring glass and plastic > Clear, intuitive user interface structured according to work processes Chroma -compatible spectrophotometers from PerkinElmer ™ Chroma™ ® PerkinElmer Lambda™ 25/35/45 PerkinElmer Lambda™ 650/750/850/950/1050 The PerkinElmer LAMBDA 25, 35 and 45 photometers are equipped with double-beam optics and are designed for extremely low-noise transmission measurements in the UV/VIS range (190 to 1100 nm) to approx. 3.5 absorption units. With the models LAMBDA 650, 750, 850, 950 and 1050, PerkinElmer offers a wide range of double-beam UV/VIS/NIR spectrophotometers with double monochromators for applications demanding maximum precision. All models have the same basic set-up with a large, flexible sample compartment and a variety of possible expansion capabilities. The LAMBDA 650 with its sensitive photomultiplier detector permits measurements to 6 absorption units in the UV/VIS range (190 to 900 nm). The LAMBDA 25 is equipped with a 1 nm fixed slit, while on the LAMBDA 35 and 45 the slit width is adjustable in the range of 0.5 to 4 nm. The pre-monochromator of the LAMBDA 45 halves the scattered light from 0.01 %T to 0.005%T. The LAMBDA 850 expands the photometric range to 8 absorption units. The LAMBDA 750, 950 and 1050 models open up the NIR range out to 3300 nm. The LAMBDA 750 and 950 are equipped with PMT/PbS detectors, and the Lambda 1050 is additionally fitted with a highly sensitive InGaAs detector for extremely precise measurements in the lower NIR range of approx. 800 to 2500 nm.
