Perkin Elmer, PE Lambda 900 UV/VIS/NIR, PELA-1050 Integrating Sphere

This Perkin-Elmer Lambda 900 is a modified UV/VIS/NIR Spectrophotometer with a PELA-1050 custom accessory, 60-mm O Spectralon® collection integrating sphere, which replaces the standard detector compartment in the instrument.

Since the PMT and PbS detectors are now mounted within a Spectralon integrating sphere, they are insensitive to any movement or slight misalignment of the beam.

The PELA-1050 is useful for measuring samples that spread the beam out slightly, including second-surface mirrors and slightly translucent samples.

• The advantage in using this PELA-1050 custom accessory is that beam alignment onto the detector optics is no longer critical.
• The PELA-1050 allows for repeatable measurements using the Lambda 900 with PELA-6000 Series VN accessories and other accessories where precise detector alignment may be an issue (such as transmittance compartment devices and variable angle accessory).
• It is also useful with the biconical reflectance (PELA-1022) accessory and the specular reflectance accessories (PELA-1025, PELA-1026, PELA-1029).
• The PELA-1050 accessory operates within the 190 nm to 2,500 nm wavelength range, using a combina... more
