OL UV-40 Ultraviolet Irradiance Standard (200 – ۴۰۰ nm)
The OL UV-40 consists of a stable, 30-watt deuterium lamp with an ultraviolet transmitting suprasil window. The lamp is calibrated for spectral irradiance over the wavelength range of 200 nm to 400 nm. The OL UV-40 serves as a convenient, accurate standard for calibrating UV radiometers and spectroradiometers, or it can be used as a known source of spectral irradiance in various UV exposure tests. The deuterium lamp is especially suited for use as an ultraviolet standard since it emits a line-free continuum in the 200 to 400 nm region. Emission is strongest at 200nm, where most instrument sensitivities are low, and weakest in the visible and infrared (which reduces stray-light problems). At 250 nm, the calibrated irradiance value for the OL UV-40 is approximately 5 times greater than the 1000-watt tungsten lamp standards of spectral irradiance. Spectral irradiance values are reported in tabular form every 10 nm from 200 to 400 nm. Typical spectral irradiance curves for the OL UV-40 and 1000 W tungsten lamp standards are shown for comparison.

۱ YEAR STANDARD WARRANTY
Optronic Laboratories warrants that the standard lamp supplied will be of the kind described or in any specification and drawings approved by Optronic Laboratories and will be free from defects in material and workmanship for 50 hours of use or one (1) year from the date of certified calibration by the original Purchaser, whichever occurs first.* During this period, Optronic Laboratories will at its option either repair, recalibrate, or replace any goods that are found to be defective in material or workmanship, provided the goods are returned to Optronic Laboratories in Orlando, Florida, with all shipping, insurance, and delivery charge prepaid (DDU Orlando, Florida). This Warranty does not extend to batteries, fuses, and glass phototubes (if any), or other items of limited durability, nor does this warranty cover damage to goods caused by leaky or otherwise defective batteries, by Purchaser use of improper batteries and by misuse or abuse, unauthorized alteration, excessive line voltage, excessive temperatures (above 160 degrees F), extreme environmental conditions (such as extremely dusty or wet environment), corrosive atmospheres or servicing by unauthorized personnel. The items returned shall only be accepted when accompanied by a written statement setting forth the nature and suspected cause of the alleged deficiencies. After the initial one (1) year warranty, repairs performed by Optronic Laboratories are covered under a limited ninety (90) day warranty. The warranty repaired (or recalibrated, or replacement) items will be returned DDU to customer. THERE ARE NO OTHER WARRANTIES, EXPRESS OR IMPLIED, (INCLUDING THE WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OR IMPLIED WARRANTY OF MERCHANTABILITY) OTHER THAN THE WARRANTY SET FORTH HEREIN.
