We offer 1000-W (OL Series 200), 200-W (OL Series 220),

and 45-W (OL Series 245) tungsten-halogen lamps, 

which are calibrated over all or part of the 250 - 2500 nm

wavelength range. 

The 1000-W and 200-W version are offered with high accuracy

and super high accuracy options.  The high accuracy standards

have a transfer uncertainly relative to the NIST Scale of ±1 -

2%, and the super high accuracy standards have a transfer

uncertainty of ±0.5%.  Additionally, the wavelength ranges

of the 1000-W and 200-W lamps can be extended out to

4500 nm.  Illuminance, color temperature, and chromaticity

values are also supplied with those standards calibrated over

the visible spectrum.

The OL FEL standards are NIST-traceable, 1000-W FEL-type

lamps.  They have tungsten coiled-coil filaments and a bi-post

base, as recommended by NIST.  They can be obtained with

calibrations over part or all of the 250 - 4500 nm wavelength

range.  Various optional accessories are available.

Application Type: Spectral irradiance, total irradiance, illuminance,

                           color temperature

Spectral Range:  250 - 4500 nm

Units of Measure: W/cm2

The OL UV-40 is a NIST-traceable, stable, 30-Watt deuterium 

lamp with a fused silica window.  It is ideal for calibrating UV 

radiometers and spectroradiometers.

Spectral Range: 200 - 400 nm

Units of Measure: W/cm2
