New Spectrophotometer Offers Choice of Detector Options

A new spectrophotometer is capable of testing a significantly expanded range of advanced materials, including highly reflective and antireflective coatings, all types of glass from clear to highly absorbing safety glass, and all types of optical filters.

The system is the first commercially available spectrophotometer to include a choice of detector options in a single instrument. High-performance integrating spheres and a universal reflectance accessory provide more accurate measurement and greater flexibility and sensitivity. Twin removable sampling compartments for standard and customized applications give further flexibility to the system.

PerkinElmer Life and Analytical Sciences (Shelton, CA, USA) launched the new spectrophotometer, Lambda 1050, at the Society of Photographic Instrumentation Engineers (SPIE) Photonics West, on January 19-24, 2008, in San Jose (CA, USA). With its unique three-detector design, the Lambda 1050 has a full scanning range from 175-3,300 nm. An indium gallium arsenide (InGaAs) detector allows for expanded testing in the 800-2,600 nm range for high sensitivity measurement in the near infrared (NIR).

Richard Begley, president, Analytical Sciences, PerkinElmer, Inc. said, "With the addition of the Lambda 1050, PerkinElmer has expanded its suite of high-performance instruments to support analysis from the deep UV to near IR.”

The new spectrophotometer's performance across the entire spectral range benefits several rapidly growing markets where innovation and environmental pressures demand exacting results: optics and display technologies--providing higher resolution and sensitivity in the NIR region for all sample types; optical coatings--affording greater accuracy, resolution, and sensitivity in the NIR region for broadband and silicon-based anti-reflective coatings and all thin film optical filters; glass--enabling accurate absorbance and transmittance measurements with improved speed, accuracy, and high dynamic range on all types of glass material.
