Gloss & Reflectance
-
Visual appearance can determine a person’s perception of a product. Colour and Gloss are two key parameters that are used to define a product’s overall quality. Perception is subjective, but Elcometer’s range of gloss meters, DOI meters and colour assessment equipment can quantify appearance measurement. The ability of a surface to reflect light without scattering is known as gloss. Using a gloss meter, gloss is measured by directing a constant intensity light beam at a fixed angle to the test surface and then by monitoring the amount of reflected light at the same angle. Different surfaces require different reflective angles.

Reflectance/Transmittance Test Set
RT-500
-
An Integrating Sphere is a hollow sphere which has its interior coated with a paint that is nearly perfectly diffuse or Lambertian and which has extremely high reflectance. Light energy introduced in an integrating sphere is reflected from the wall and distributed uniformly around the interior. A detector which is placed at a hole or 'Port' in the sphere wall sees an output which is completely independent of the angularproperties of the input light. The independence of the output of a sphere from the angular properties of the input and the uniform internal distribution of light make integrating spheres ideal for many uses.

VHF/UHF Handheld Signal Location Antennas
Type NVF-2
-
The Type NVF-2 series of handheld directional antennas are used to locate interfering signals or noise in either the 420 – 470 MHz (Type NVF-2A) or the 900 MHz ISM band or cellular telephone bands (Type NVF-2B). Both models incorporate a solid reflector positioned behind a resonated half wave driven element, both elements being mounted on a fiberglass rod with an integral pistol grip. The configuration of the reflector and driven element are such that a deep null in the signal being received will occur when the antenna is pointed in the direction of the signal being radiated. A T-pad resistive attenuator is also incorporated in the antenna mounting enclosure to aid in the direction finding process on very strong signals or when excessive reflections present multiple returns.

Bare Fiber Aligner
1120
-
The Photon Kinetics 1120 Bare Fiber Aligner makes it possible to reduce test setup time to seconds, thereby reducing overall testing cost. Just strip the fiber, scribe and break it (or use a more precise fiber cleaver, if desired) and then insert the prepared end into the 1120. In an instant, the fiber is coupled to your OTDR or chromatic dispersion test system with low optical loss and low reflectance. The 1120's compact, ergonomic industrial design is well-suited for low to moderate volume fiber and cable testing applications where automated fiber alignment systems are less economical. It is particularly useful as part of an in-process or finished cable test station employing either the 8000i or 8000 OTDR, and the OASYS.net OTDR Automation Software.

Transition Time Converters
-
These converters have been designed to convert the transition times of instruments with fixed, fast transition times, to slower, fixed transition-times (150 ps, 250 ps, 500 ps, 1 ns, 2 ns); hence reducing the signal bandwidth. All transition-times are between 10% and 90% of amplitude.The design of these converters ensures very low signal reflection far beyond the 3 dB point. Reducing the signal transition-times also increases the overall pulse-performance for overshoot/reflection sensitive applications. The converters are fitted with two SMA connectors, one male, one female.

Deep Ultraviolet Spectrophotometer System
VUVAS-10X
-
A new ultraviolet spectrophotometer system for optical metrology just arrived at NASA Goddard! The VUVAS-10X spectrophotometer works best in the 90 to 160 nanometer wavelength range, also known as deep or vacuum ultraviolet (VUV) region. It uses a windowless hydrogen plasma light source and differential pump section to reach many wavelengths beyond those of conventional deuterium lamps. The source also works with other gases, or gas mixtures, for atomic spectral line emission from about 30 nanometers (double ionized Helium gas) up to the Visible light range. The new spectrophotometer system, McPherson VUVAS-10X, uses a one-meter focal length high-resolution monochromator with the special light source, scintillated detector and Model 121 goniometric sample chamber. The system is ideal for optical transmission, absorbance and specular reflectance at incident angles up to 60 degrees. This McPherson spectrophotometer system will help develop, inspect and qualify optical materials and coatings used for very high altitude and extraterrestrial space flight missions.

Anechoic Chambers
-
Eckel Noise Control Technologies
Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or SuperSoft panels, depending on performance level required and cut-off desired.

kSA Emissometer
-
The kSA Emissometer is designed to quickly and easily generate high-resolution diffuse and specular reflectance and total emissivity maps of MOCVD carriers. Carrier emissivity variation means temperature non-uniformity, which can lead to reduced device yield and possibly complete growth run failure. With the kSA Emissometer, emissivity changes can be tracked to determine carrier end-of-life, without wasting growth runs. The kSA Emissometer also detects unwanted residual deposits after baking, and easily identifies carrier surface defects, scratches, microcracks and pits that are not visible to the eye.
