Spectrophotometer --

The Spectrocam hand-held spectrophotometer is a cost-effective way to characterize the colors of parts, prints, or materials at specific points.

Contact AutoVision for ordering information.


DESCRIPTION

The spectrophotometer is able to measure consistent spectral measurement on parts or material in the visible spectral range
(400 - 700nm).

The consistency comes from the way the spectrophotometer works: measurements are made in contact with a part or material. It also provides its own self-referencing flash Xenon lighting.

Although the spectrophotometer is non-imaging, it is a very good compliment to spectral imaging setups to establish truth data.

Measurements can be very consistent and great for comparing results from any spectral device.

Specifications Spectrocam 75 RE

With its unique patent pending design, the Spectrocam matches or even exceeds specifications of high end spectrophotometers at a fraction of the price.

As one of the few spectrographic meters on the market the Spectrocam meets ISO standards for color measurement. At the same time the Spectrocam measures many times faster and is more versatile in use than any other handheld spectrophotometers on the market.

Included with the Spectrocam is a ISO standard black scan plate and scan ruler for measuring color bars allowing you to measure 18 targets in less than 10 seconds. It also includes a white reference and monitor accessory designed to calibrate both CRT and LCD monitors in 30 seconds.
