PE LAMBDA 900 950 1050 Variable Angle Specular Reflectance Accessory(VASRA)

[Absolute Specular Reflectance Accessory(ASRA)] This PELA-1029 Absolute Specular Reflectance Accessory(V- W optical geometry) is designed for PE Lambda- 800/850/900/950/1050 UV-VIS-NIR Spectrophotometers.

The V-W Geometry introduces two reflections at the sample.

• This is advantageous for samples with high reflectivity since the signal change to be measured is twice as large.
• However, the need for two reflections makes this unsuitable for small samples, especially at higher angles of incidence.
• Features/Principle:

It is also unsuitable for samples of low reflectance.

• Wavelength Range: 175~3300 nm (200~2500 nm if using a Collection Sphere)
• Minimum Sample Size: 20 mm x 20 mm

The PELA-1029 Absolute Specular Reflectance Accessory is the primary instrument used in the characterization of the reflectance properties of optical materials worldwide.
