Description
[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.
Key Features
- 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:
Applications
It is also unsuitable for samples of low reflectance.
Specifications
- Wavelength Range: 175~3300 nm (200~2500 nm if using a Collection Sphere)
- Minimum Sample Size: 20 mm x 20 mm
Included Items
The PELA-1029 Absolute Specular Reflectance Accessory is the primary instrument used in the characterization of the reflectance properties of optical materials worldwide.
