The Cary 500E is a double-beam, double-grating SPM with a 0.18 < λ < 3.30 μm range. This instrument is the predecessor to the Cary 5000; ODA acquired its unit when the company was established in 1991. The standard sources are deuterium and tungsten-halogen lamps, but mercury and other lamps can be substituted in the source turret. Its monochromator is driven by a stepping motor for accurate normalization and background subtraction. The instrument self-calibrates in wavelength on every initialization with its deuterium lamp. The sample compartment is large and flexible. The detectors are a UV-enhanced photomultiplier and a cooled lead sulfide cell.

The PE 983G is favored by many optical fabricators and coaters over all FTIR systems for its photometric accuracy and stability; it is the best commercially available dispersive SPM ever made. Its 2 < < 56 µm spectral range complements that of the Cary 500E. It employs a Globar source and a thermocouple detector; four gratings on a turret cover the wide spectral range. This model is employed by the National Physical Laboratory of Great Britain to produce the world's most widely used IR primary reflectance standard mirrors

This instrument was obtained in 2000 to replace the aging Nicolet 740; it extends our IR capabilities to diffuse transmittance and reflectance measurements. To that end, it is equipped with a Labsphere Infragold™ 102 mm diameter integrating sphere. Its 2 < < 25 µm range overlaps that of the Cary 5E, and its high sensitivity complements the high accuracy of the Perkin-Elmer 983G.

Accessory:

Labsphere Infragold™ 102-mm diameter integrating sphere

Standard:

Infragold™ High R Standard

ODA acquired a Varian Eclipse fluorometer in early 2003. This system can generate excitation and emission spectra over a 190 < < 1100 nm spectral range. It can accommodate both solids - 15° incident/75° exitent angles - and liquids in cuvettes - 90° reflectance angles. The system can operate at slit widths ranging from 1.5 to 5 nm, and with various filter and attenuator programs, and can make zero order measurements in both excitation and emission. It has a broader spectral range than the FluoroMax 2, described below.

Standard:

Olavene fluorescence standard

The FluoroMax 2™ UV-Vis-NIR fluorometer, built by Jobin-Yvon/Spex, is available to ODA under an agreement with the Arizona Materials Laboratory of the University of Arizona. This system can generate excitation and emission spectra over a 200 < < 900 nm spectral range. It can accommodate both solids - 20° incident/70° exitent angles - and liquids in cuvettes - 90° reflectance angles. The photon-counting detector system provides a higher sensitivity than the Varian Eclipse,

Olavene fluorescence standard

T he Helios™ Laser Reflectometer measures transmittance and absolute reflectance at = 10.6 µm. Based on a Synrad CO2 laser source, the system can work at incident angles of 10° and 45° and with s, p, s=p, and circular polarizations. Three carousels accommodate 1" diameter, 2" diameter, and 2" square samples. This system can produce critical absolute R standards for the mid-IR.

In 2001, ODA totally upgraded its Micromap noncontact optical profilometry system. Based on Moire interferometry, the system can assess rms, average, and peak-to-valley roughnesses and step heights ranging from a few tenths nm to about 37 µm through a user-friendly, versatile Windows 2000 software interface. The sample area measured can be as large as 1 mm square with horizontal resolution of about 1 µm or as small as 0.3 mm square with a horizontal resolution of about 0.5 µm.

Standard:

VLSI Standards Inc. SHS-880 QC Thickness Standard

This system was acquired by ODA in 2006 to measure the haze of large samples, specifically armor glass samples, which can be up to 13 cm thick and 60 cm square. In addition to haze, the instrument can measure total transmittance and clarity. Multiple measurements can be combined and variation can be statistically reduced. The Haze-Gard Plus conforms to ASTM D-1003 and D-1044.
