Calibrated Spectral andLuminous Flux Standards
NIST traceable standards forlight measurement systems
Confidence
Labsphere’s Total Spectral and Total Luminous Flux Lamp
Standards are selected for their stability and reproducibility.
Each standard has been carefully screened, seasoned, andcalibrated at our manufacturing facility under the guidelines
recommended by the NVLAP accredited ISO 17025 practices
for the highest degree of confidence.
Labsphere’s Lamp Standards of Total Spectral Flux provide
an exceptional artifact for calibrating integrating sphere
spectrometers for total spectral radiant flux responsivity
from 350 to 1050 nm. All of Labsphere’s standard lamps are
first seasoned for 1% of their rated life and then screened
for stability and repeatable performance before they are
selected for calibration.
The selected lamps are then calibrated directly to theNIST spectral flux reference, for a calibration result you
can rely on. All calibration certificates include a complete
uncertainty analysis.
Multiple choices
Labsphere’s lamp standards may be purchased individuallyor in sets of three’s, following the recommendations ofnational laboratories and industry standards for lamp
photometry. The use of three lamps interchangeably
prolongs the useful life of each lamp. A multiple lamp set
allows the user to check the lamps against each other toverify calibration data over time. A calibration certificate
verifies traceability to NIST is provided with each lamp.

Easy to use
All lamp standards include a calibration certificate and spectral
flux data in W/nm or total luminous flux value with operating
current. The spectral flux data is provided on a CD for
uploading into Labsphere’s Integral® LM Software sold with
our world leading illumia®Plus2 and illumia®Pro3 Light
Measurement Systems for total spectral flux.
Labsphere’s Calibrated Spectral Flux Standards are available
in sets of three spectrally calibrated lamps. CSFS-040 is a setof three SCL-040, 40 lumen spectrally calibrated optical grade
krypton lamps. CSFS-650 and CSFS-1400 are sets of three
SCL-650 and SCL-1400, 650 and 1400 lumen spectrally
calibrated tungsten halogen lamps. The SCL-040 isrecommended for use with smaller and more sensitive
illumiaPlus2 systems while the SCL-650 and SCL-1400 arerecommended for larger illumiaPlus2 systems. The 2PI versions
are wall mounted internal calibration sources.

Labsphere recommends procuring a set of three calibrated lamps at one time.
The best practice recommendation is to use the identical calibrated lamps of a set as reference standards for one another in the set.
