Since 1999, Avian Technologies has been active in the development of reflectance standards, materials and coatings, integrating spheres, and provision of measurement services for the pharmaceutical, agricultural, and optical industries.
Their diffuse reflectance materials and coatings are used throughout the world in a wide variety of industries. Applications for these coatings and materials are found in remote sensing devices, environmental/agricultural monitoring instrumentation, and as standards in biological/biomedical probes.
Avian Technologies' standards, all traceable to NIST
The kits consist of a three part press, two calibrated cups for the production of the standards, and 500g of either highly purified barium sulphate or PTFE
Transmittance Standards are useful in the calibration of spectrophotometric, photometric, or radiometric systems. Calibrated filters are used to assess the dynamic range of detectors and optical systems.
The fluorescent properties of the FTS (Professor Frederick T. Simon) tiles make them ideal for applications involving the measurement of fluorescent whitening agents (FWA) common in office papers. In measurement it is always good practice to use similar standards whenever possible.
Axiphos Plastic and UV
Avian Technologies uses a modification of its Avian-D coating technology along with a highly stable tinting system to produce the targets. These targets have been used in laser range-finding in harsh conditions (the Australian outback) as well as more traditional remote sensing applications.[ Send Enquiry ]
Fluorilon-99W™ is a stable white thermoplastic with extremely high diffuse reflectance. The material is both thermally (>300°C), physically, and chemically stable to all but the most hostile environments. The sintered PTFE
This is a well characterised coating that has been used for diffuse reflectance applications for more than 20 years. It is relatively easy and inexpensive to apply.
Avian-D coating is a two-part water based urethane coating uses a different pigment system than Avian-B and can be applied to a wide variety of substrates.
Avian-D coating is ideal for field applications where the coating will experience variations in temperature and humidity, such as calibration plates and remote sensing targets. It is ideal for large integrating spheres used in lamp measurement photometry where large amounts of UV
Warsash Scientific offers two gold materials that combine the high reflectance of Epner LaserGold® and the surface preparation technology of Avian Technologies to give optimum diffuse reflectance in the near-NIR and mid-NIR. The NIR
Reflectance of the NIR
This is a spray on, two part water based urethane coating that exhibits low reflectance over a wide wavelength range. The water-borne coating exhibits very low gloss and is quite durable compared to most low reflectance coatings. It is easily mixed and may be applied with standard spraying equipment. Clean up is easily done with water and detergent.
The coating passes and exceeds Mil spec for live agents and durability. It is a low VOC
The reflectance is <3.5% over most of the UV-Vis-NIR
Avian-DS black is an etch-anodize process similar to what was known as Martin Black. Avian-DS, however, is even more absorbent of light. It is the blackest material that Avian Technologies have seen in almost twenty years in this field. Coating is limited to parts fabricated from aluminium. This is a batch process, so small lots tend to be very expensive but the coating is economical for large lots or OEM quantities. This coating can only be applied to aluminium substrates.
Avian-EP Black is an electrochemical process that can be applied to almost any substrate including plastic or glass. The coating is highly diffuse but somewhat fragile, so its use in applications that require handling of the optical surface are not recommended.
Optically, Avian-EP Black is very highly absorbent in the UV-Vis-NIR
