Light metrology instruments, and reflective materials on display from leader in light testing and measurement
North Sutton, New Hampshire (December 20, 2007) – Labsphere, Inc., a leader in light metrology, will be presenting its line of light metrology instruments and reflective materials and coatings during the SPIE Photonics West 2008 conference and exhibition January 22-24, 2008 at the McHenry Convention Center (San Jose, Calif.). In addition to regular product displays at booth number 237, the company will be hosting an applications solution demonstration and offering personalized one-on-one consults at its booth.
Labsphere light metrology and reflective materials and coatings products on display will include new solutions for LED and SSL test and measurement, the new USS-800C, one of a series of uniform radiance source systems for digital camera calibration, and Spectralon® and Spectraflect® coating examples. Labsphere’s diffuse reflectance materials can be applied to customer-supplied parts, or complete components can be designed and machined to specification. Labsphere’s strength is in customizing its instruments, and materials and coatings products, based on customer requirements.
Application engineers will be on hand to discuss custom solutions. Personalized half hour consultations can be booked in advance of the show by contacting Labsphere at labsphere@labsphere.com. In addition, the company will host a presentation entitled “Labsphere Solutions for your Application” Thursday, January 24 at 11:30 am in the Opto Town Square One Demo area.

Increased dynamic range for use in developing highest levels of sun protection products
North Sutton, New Hampshire (December 5, 2007) – To keep pace with demanding industry methods for quality assurance and UVA Protection Factor (UVA-PF) analysis in the formulation, development and testing of sunscreen products, Labsphere has introduced its next generation UV Transmittance Analyzer, the UV-2000S. Designed to rapidly measure the spectral transmittance of sunscreen products, especially those with high protection factors SPF 50 and above, the UV-2000S builds on the platform of Labsphere’s industry standard UV-1000S with increased dynamic range and functionality.
The rugged bench top instrument quickly measures the diffuse transmittance of a product sample over the 280 nm – 410 nm wavelength range. A dual beam spectrometer with diffuse illumination accommodates accurate measurement of highly scattering samples. No filters are needed to prevent sample overexposure.
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.
With accurate in-vitro measurement of SPF and UVA-PF, the UV-2000S can greatly reduce the need for expensive in-vivo testing protocols, such as UVA-PF based on Persistent Pigment Darkening. The unit’s sample positioning stage, with user defined sample patterns, enables fast positioning with the accuracy required by approved and proposed UVA-PF test methods. The RoHS compliant instrument meets corporate environmental mandates on hazardous substances.
