Bare metals are classified as opaque metals and do not allow any light to pass through them. In opaque metals, the specular reflection and diffuse reflection are key to defining the light interaction of this unique sample type. For bare metals both color and gloss are seen in the specular reflection which makes up a large portion of the reflection.

A small amount of diffuse reflection results from imperfections in the metals surface that causes the specular reflection to scatter. Having extended life, the xenon lamp will last at least eight years in typical use and is easily replaced by the user. To ensure measurement repeatability and stability, ColorQuest XE uses true double-beam optics that monitor light reflected from the sphere and spectrally compensates for any variation.

To ensure colormetric measurement accuracy and inter-instrument agreement, each system is tested with calibrated color tiles traceable to the NPL. Easily measure samples of all types and sizes. The geometry of the ColorQuest XE allows you to perform color measurement of transparent, translucent and opaque samples. Solid samples are easily positioned and supported at the reflectance port with the ergonomically designed sample clamp.

For measurement of powders, granules and opaque liquids the Reflectance Sample Shelf accessory would be used to position a sample cell. The large transmission compartment is open an three sides to make sample measurement easy.

The compartment can accommodate samples ranging from thin films and glass to 80mm transmission cells. Diffuse transmittance, regular direct transmittance, and haze can be measured. The Specular port cover position is controlled by the system computer, which also stores standardization modes for quick and automatic recall when multiple mode measurements are made. When switching modes, the ColorQuest XE automatically changes its lens system and confirms that the proper port aperture is in place.

An optional sample viewing screen assures the position of samples at the reflectance port. UV content of light striking a sample is automatically adjusted. This provides accuracy, stability and reading agreement between multiple instruments for whiteness and brightness measurements.

Controlling the UV energy is superior to "numerical calculation" systems that assume fluorescent linearity. The ColorQuest XE is engineered to be reliable in industrial environments. The Spectraflect coated sphere doesn't yellow like conventional BaSO 4 and will remain highly reflective for years. You can order single Haze standards or the full set of 5 haze standards through HunterLab for use with any of our sphere instruments — UltraScan PRO and UltraScan VIS These solid, transparent plastic plaques calibrated or uncalibrated can be effective in monitoring instrument performance in measuring wide angle scattering over time.

The answer is yes, you need to keep the white tile at the reflectance port of HunterLab sphere instruments whenever you perform transmission measurements in TTRAN Total Transmission or RTRAN Regular Transmission modes In colorimetric sphere instruments, the same fixed light path is used for color measurements in both reflectance and transmission. The HunterLab UltraScan XE is a dual beam xenon flash spectrophotometer with a wavelength range from to nanometers nm All tristimulus integrations are based on a triangular bandpass of ten nm and a wavelength interval of ten nm Buying used equipment doesn't always have to be a shot in the dark.

ERIC value is a dimensionless ratio of the light absorption coefficient of pulp or paper containing ink to the light absorption coefficient of the ink itself, both being determined at a wavelength of nm The User will need to calibrate the ERIC value to report in ppom with an added Ink Absorption Coefficient determined by the User. This version of the software protects and maintains complete and accurate records, limits system access, performs authority checks, provides a computer-generated audit trail and includes electronic signature It meets the software requirements for 21 CFR Part 11 compliance EasyMatch QC is available in Chinese, English, French, German, Italian.

We also offer a. Glass Sample Cup: 64mm 2. You are bidding on a used HunterLab ColorQuest II Sphere spectrophotometer color measurement device This equipment measures reflected or transmitted color of a sample The department stated that the item works We tested it to power on and it is sold AS-IS.
