A High-precision spectrophotometer suitable for color management of small products.

Introducing a new high-precision spectrophotometer designed for color management of small products. The Spectrophotometer CF-300 has the ability to measure small target areas, non-contact measurement, fast and accurate measurement.

The Spectrophotometer CF-300 is capable of measuring areas as small as 0.75 x 1 mm, making it idea to measure products with small measuring areas, such as watch dials, bands, smartphone parts, eyeglass frames, zippers, buttons, fountain pens, etc. With a viewfinder, you can accurately align the measurement part, effectively reducing measurement errors.

The Spectrophotometer CF-300 allows for non-contact measurement, by using an integrating sphere capable of measuring color even at a distance of 1 mm from the target.

The Spectrophotometer CF-300 requires only about 0.1 sec per measurement making it capable of continuous measurement at a minimum interval of about 0.2 sec, the CF-300 can perform 5 measurements per second*. Improving efficiency of quality control via high-speed non-contact measurements on production lines.

* For high-speed measurement use, the software must be customized to the customer’s line conditions.
