Russian Opal Glass

Useful as a durable white standard in the visible-near infrared, Russian Opal Glass MC-20 is primarily used in its glossy form. The glossy Russian opal is easily cleaned and quite stable. Russian Opal is the preferred standard for direction/ directional geometry such as 0/45 or for multi-angle spectroscopy. It is also useful as a standard for hemispherical measurements.

Standards are available as 2" (50.8 mm) squares in a black holder and a wooden box for protection. Larger sizes (up to 90 mm square) are available by special order.

Matte Russian Opal Glass

In conjunction with our partners in Scandinavia, Mitaten Finland Ab, Avian Technologies has developed a new, highly matte Russian Opal Glass standard. The standard has gloss levels of <0.2 units at 60°.   The material also offers excellent reflectance properties far into the NIR. This standard has found great usage in the paper industry in Europe.

We currently offer the standard in a single configuration. The active area of the standard   is 50 mm diameter, mounted in a Delrin holder with cover.

Gray Scale Standards

Gray scale standards are essential for establishing the photometric linearity of a reflectance spectrometer. These are used in the same way neutral density filters are used in transmittance instruments. Avian Technologies Fluorilon(TM) Gray Scale standards allow the user to calibrate their instrument over a 2 decade range of reflectance, which is well over the typical range seen by a reflectance instrument. The materials are highly diffuse and therefore have little angular dependence and almost no gloss, which means that specular included and excluded geometries should show little difference in reflectance values

The standard sets consist of four standards of nominal reflectance (at 550 nm) of 2%, 10%, 50%, and 99% reflectance. The standards are cupped in a Delrin holder with cap. The sets are presented in a waterproof plastic box.

‘Encapsulated’ Grey Scale and Wavelength Standards to meet USP 1119

Avian Technologies is introducing new ‘encapsulated’ grey scale and wavelength standards to meet USP 1119. The standards are identical to the Fluorilon FSS-08-02c kit except the Fluorilon is encased in a Delrin™ holder with a 2” diameter BK-7 window. The overall size of the standard is 2.400” diameter (61 mm) and 0.620” thick (15.88 mm). The size of both the grey scale and wavelength standards is identical to enable fixturing for most instruments designed to measure pharmaceutical on-line processes.

The wavelength standard has the same components as the National Institute of Technology’s SRM-1920a, with a small amount of an inert, spectrally non-absorbing binder. Unlike sintered equivalents of SRM-1920a, this standard exhibits no peak shifting and is both durable and stable.

Both grey scale and wavelength standard have a small, re-sealable port in the top to allow for conditioning of the standard in a controlled humidity environment.

Part # Description  
EFSS-08-02c Set of eight grey scale standards, cella with BK-7 window, nominal 8°/hemispherical reflectance of 2%, 5%, 10%, 20%, 40%, 60%, 80%, and 99%, calibrated from 400-2400 nm, traceable to NIST/NRC. Data provided as hard copy and electronically on diskette or CD. Set Price: $3000.00

EWCQ-P1920a-02c As above, fused silica windows Standard Price: $1290

EFSS-08-02c kit comes in a waterproof plastic box to hold eight standards. EWC-P1920a-02c comes in an individual wooden box.

CERAM Gray Scale Tile Set

In some cases, especially where durability and frequent cleaning are necessary or organic fumes or grease are present, ceramic tile standards provide a better choice than matte standards. In addition, these targets are more suited to small spot measurements or at 0:45 geometry, where the specular component is automatically excluded.

The standard set consists of nine standards (white, 80%, 70%, 60%, 50%, 33%, 8%, approximately 1% black, and a black glass) in Delrin holders with a 1" mounting counter bore in the back of the standard. The standards are presented in a hinged wooden box.

Typical values of reflectance, along with L*a*b* and x, y, Y values included.

Color Standards

CERAM Color Standard Sets

CERAM Research Ceramics Standards, also known as BCRA Series II tiles, are the popular standards for color in the US and abroad. These standards can be used to calibrate color spectrophotometers in both hemispherical and directional/directional geometry. Avian Technologies BCRA sets consist of fourteen 2" tiles (the standard BCRA set plus a black and a white tile), mounted and sealed to prevent effects of humidity. Standards come in a wooden box with a desiccant.

For an in-depth analysis of CERAM tiles, refer to "The BCRA-NPL Ceramic Color Standards Series II- Master Spectral Reflectance and Thermochromism Data", F. Malkin, J. Larkin, J. Verrill, and R. Wardman, JSDC 84, 84-94 (1997).

At this time, these standards are calibrated at 8°/hemispherical geometry only.

Individual Color Standards

If you wish to assure an instrument stays within calibration but do not have the time it takes to run a full set of CERAM standards, it is suggested that a single time with some spectral structure be used**. We have found that the best tile within the BCRA Series II set is the cyan tile. We offer this tile either calibrated or uncalibrated, made to the same specifications as the set described above. The tile is sealed in a delrin holder and come shipped in hinged a wooden box.

Avian Ceramic Color Standards

Avian Technologies, in partnership with Mt. Baker Research, has developed a complete line of ceramic color transfer standards. These tiles are more fully described here, or download this PDF for a complete description, including spectral reflectance data. Mt. Baker Research has performed other analyses, including a detailed gamut analysis comparing our new tiles with the Ceram series and a few other color standards.


Basic Colors

Grey Scale and Pastel Colors

Special Colors

The chart at right shows the color distribution (CIELAB b* vs a*) of the three Avian tiles sets in comparison to the chromatic BCRA tiles. Many of the Avian tiles extend the available gamut of colors. Also note that the additional tiles span the gamut very well.

In general, t
his more complete coverage of color space should improve results for many applications such device profiling and instrument characterization and evaluation.
