What it is

The Lambda 950 is a double-beam, double-monochromator, all-reflecting optical system operating in the UV, visible, and near-infrared range.[1]

The instrument covers a wavelength range of 175 to 3300 nm.[2]

How it works

The Lambda 950 uses deuterium and tungsten-halogen light sources that automatically switch during monochromator slewing, along with programmed optical filters that also change automatically.[1]

Spectral bandwidth is selectable from 0.1 nm to 5.0 nm in 0.01 nm increments.[1]

Interchangeable snap-in modules accommodate varied sample types, and a Universal Reflectance Accessory allows angle-resolved measurements from 8° to 65° with a 0.5° step size.[2]

Where it fits in the process flow

General reference — not yet source-verified

In a fab environment, it is typically employed for off-line metrology and evaluation of optical coatings, thin films, and substrates to verify spectral properties such as reflectance, transmittance, and bandgap.

Applications

Applications include glancing reflectance measurement of glass and other optical components, quantification of colored materials, identification of material concentration via the Beer-Lambert law, and determination of semiconductor bandgap.[2]

The instrument supports total, diffuse, and specular transmission and reflectance measurements, and is used in materials science, pharmaceuticals, environmental monitoring, academic research, and food and agriculture analysis.[1]
