Labsphere’s
UV-1000F Ultraviolet Transmittance Analyzer is specifically designed to meet the
rigorous quality assurance needs of the textile industry. This rugged, convenient
bench top instrument quickly and accurately measures the spectral transmittance
of a fabric sample, then automatically converts data to a Ultraviolet Protective
Factor (UPF) for determining the fabric’s protective ability. |
The UV-1000F operates
by measuring the diffuse transmittance of fabrics in the ultraviolet region (250
-450 nm). A dual diode array spectrometer with a xenon flashlamp, optimized for
UV emission, and an integrating sphere provides instantaneous spectral acquisition.
The diffuse illumination geometry of the sphere measures the transmittance from
all angles and pathlengths through the sample, and utilizes the total energy from
the xenon flashlamp for optimal signal-to-noise performance. This design delivers
exceptional wavelength stability and flash-to-flash repeatability. The optical
design meets the requirements of the Australian/New Zealand Standard AS/NZS 4399:1996
"Sun Protective Clothing—Evaluation and Classification," British Standard BS 7914:1998
"Method of Test for Penetration of Erythemally Weighted Solar Ultraviolet Radiation
Through Clothing Fabrics," and US Standard AATCC 183-1998 "Transmittance or Blocking
of Erythemally Weighted Ultraviolet Radiation Through Fabrics."
The efficiency
of the dual diode array spectrometer, coupled with the xenon flashlamp gives reliable
and repeatable measurement results in seconds. Instrument software automatically
calculates the average value of the UVB (280 - 315 nm) and UVA (315 - 400 nm)
spectral regions and instantly converts the data to give you an accurate UPF rating
fabrics ultraviolet blocking ability.
Windows compatible application software provides an easy-to-use
environment with pull-down menus, dialog boxes and built-in report generation
functions. The application software guides the operator through analysis without
complicated routines. This means minimal amount of operator training. One-touch
sample analysis gives results in less than 5 seconds and information is quickly
converted to a printed report or exported to other spreadsheet or data processing
programs for statistical analysis.
A built-in report
function generates essential information at the click of a button. Reports include
necessary GLP/GMP information such as date, time, operator name, sample identification
and test parameters. Reports are viewed on your PC, printed, or exported as text
to data processing software for further review.
Application software includes
preprogrammed solar spectral irradiance and CIE erythemal action spectra to precisely
calculate the UPF value of the sample. Spectral irradiance data and test method
parameters are easily set to your specific needs. Multiple scans are averaged
and viewed simultaneously in easy-to-read formats.

For validation
of the UV-1000F Ultraviolet Transmittance Analyzer’s performance, application
software includes an integrated Performance Validation Routine. This allows for
on-site validation and revalidation and ensures optimum instrument performance.
A set of our four calibrated standards is included with each analyzer to validate
the accuracy of both wavelength and photometric scales. The set includes three
photometric standards and a wavelength calibration standard. The standards are
mounted in specially designed holders that automatically orient and position the
standard to ensure precise placement each time the validation routine is performed.
The instrument Performance Validation Routine assures quality measurement results
as well as satisfying the requirements of regulatory agencies.
