Available in 400 and 1000 lumen models, Forward Flux Lamp Standards can be used to calibrate integrating sphere spectrometers for total forward spectral radiant flux responsivity from 350 nm to 1050 nm.  The lamp standards are designed to meet the recommended practices of the Engineering Society of North America (IESNA) LM-79 for 2π measurements of solid state lighting. 

Each lamp standard is carefully seasoned, screened, and calibrated.  All lamp standards are first seasoned for 1% of their rated life, and then screened for stability and repeatable performance, before transferring the lumen directly from a NIST lumen reference.  The result is an accurate and reliable system calibration with a lamp standard distribution similar to the light sources being tested.

Lamp standards include a calibration certificate and calibration data on CD-ROM.  Labsphere is an ISO 9001: 2000 Certified company.

Available in standard 12, 20 and 40 inch diameters, the HalfMoon system provides an alternative to integrating sphere photometer and goniophotometer methods of measuring total forward spectral flux of forward emitting lamps, luminaires and displays.  The unique compact design, available only from Labsphere and Otsuka, creates a virtual integrating sphere by pairing an interior mirrored surface cap with half an orb coated with Labsphere’s highly reflective diffuse Spectraflect® material.  The resulting system saves space, minimizes absorption errors and facilitates quick sample changes.

While the HalfMoon has a small footprint, it shares the accuracy of an integrating sphere, but with twice the efficiency of an integrating sphere of the same diameter.  The center sample mounting keeps base electronics and thermal management peripherals out of the detection area to reduce absorption errors.  The easily accessible mount also reduces the time to set up and change samples for measurement.  The system is configured for base up to horizontal measurement geometry, allowing products to be tested in the same orientation as the fixtures they are intended for.

In production environments, the dust in the air can settle into integrating spheres used for light testing and measurement, resulting in a lack of spatial uniformity that leads to measurement errors.  Labsphere recommends annual recoating of spheres operating in warehouses to maintain measurement consistency.  Sending away large area spheres (some as large as 76 inches in diameter) can be a packing and shipping hassle that creates increased production downtime. 

With its new service Labsphere recoats customer spheres on-site, vastly reducing production downtime.  Labsphere’s coating representatives are able to apply the company’s proven, proprietary Spectraflect and Duraflect coatings to spheres in the field with the same care and attention given to those coated at Labsphere’s facility. 

Labsphere is currently offering a 20 percent price reduction for on-site recoating services booked before December 31, 2008.  For more information and to schedule an on-site recoating appointment, phone +1 (603) 927-4266, or send an e-mail to labsphere@labsphere.com.

For research and development of sunscreens and cosmetics formulated with sunscreen, the increased dynamic range and functionality of the UV-2000S meets new standards for in-vitro sun care product analysis put forth by COLIPA and Boots Star. The rugged bench top instrument quickly measures the diffuse transmittance of a product sample over the 250 nm – 450 nm ultraviolet wavelength range. A new dual beam spectrometer with xenon flash lamp accommodates accurate measurement of highly scattering samples. The sample positioning stage allows for multiple readings at different points on the slide for a more accurate reading.

The application software automatically converts measurement data to provide the Sun Protective Factor (SPF), UVA to UVB ratio, critical wavelength, Boot Star Rating, and UVA-PF (COLIPA Method). The platform allows users to view, archive, retrieve and export data for measurements on both bare substrates and product substrates. The software is structured to support evolving regional methods for analyzing product UVA Protection Factor (e.g., revised Boot Star, PA+ Method, UVAI/UV Ratio, etc.), meeting foreseeable changes and challenges in the dynamic sun protection industry.
