View our latest version of this instrument, the CM-3600A.

The CM-3600d bench-top spectrophotometer is an exceptionally accurate instrument which can be controlled by a PC using Windows software. It has the capability of measuring at 10nm over a full range of wavelengths from 360-740nm using double-beam technology and a dual-channel sensor.

The CM-3600d includes components which reduce time switching between SCI and SCE and filter movements. It is equipped with three measurement diameters, 25.4mm, 8mm, and 4mm to easily measure various sample sizes. This instrument is highly advanced, with features for numerical gloss and UV control as well as having the ability to measure the color of transparency. The device is compact and features a viewfinder, making it lightweight and easy to measure from a seated position.

This instrument is compatible with SpectraMagic NX software which is easy-to-use and displays multiple views of data results which can be edited. Target data of the primary target can be associated to two or more secondary targets, allowing for sophisticated QC applications, such as checking for color difference.

A variety of graphs can be used to display information, preconfigured templates are available, and a status window is available to show instrument information at a glance. Data compiled with older software is compatible and can be transferred to the newest updated software. If Excel is needed to show data, the information can also be easily exported. A Navigation Function and Color Tutorial are included with the software for additional information.
