Perkin Elmer multifunctional spectrophotometers

 Two Perkin Elmer Lambda 1050 UV-Vis-NIR spectrophotometers for both specular and diffuse transmission and reflection measurements. One of the instruments is dedicated to diffuse transmission and reflection measurements, using an integrating sphere or praying mantis. Using the latter attachment, measurements can be performed under a controller atmosphere and at elevated temperature. The other instrument is equipped with a TAMS (total absolute measurement system) and can be used for angle dependent transmission and reflection measurements under controlled polarization conditions, including measurement of BRDF (bidirectional reflection distribution function) and mapping of wafer surfaces.

UV-VIS-NIR spectrophotometer

Double beam – double monochromator UV-VIS-NIR spectrophotometer for the optical characterisation of thin films. Measurement range from 200 to 3300nm. An extension is available to measure the (diffuse) reflectance of powders and thin films (200 - 2000nm), using an integrating sphere.

Type: Varian Cary 500

 
Fluorescence spectrometer

Photoluminescence setup, enabling high resolution excitation and emission measurements. The combination of a Xe arc lamp and a double excitation monochromator allows selecting an excitation in the range from 250 to 900nm, with narrow band width and low stray light. At the emission side, two detectors are available for measurements between 300 and 1650nm. The setup can be extended with a cryostat, for measurements between 4 and 500K.

Type: Edinburgh FS920

Intensified CCD

This instrument is used for measuring integrated and time-resolved optical emission spectra (both electro- and photoluminescence). On periodic signals, a time resolution down to 2 ns can be obtained. It is coupled to a 0.5 m Ebert monochomator. For photoluminescence decay measurements, a 337 nm pulsed nitrogen laser is available (pulse length < 1ns). Using the dye extension, the excitation can be tuned between 360 and 600nm.

Type: Andor DH720

Tunable laser

Our tunable laser system comprises a nanosecond optical parametric oscillator and Q-switched pump laser in a single housing. It features hands-free wavelength tuning from 210 nm to 2600 nm, a 10 Hz repeptition rate, 4 ns pulse duration at an energy of about 10 mJ. Direct outputs at 1064 nm, 532 nm and 355 nm are available. Useful for decay time measurements, laser ablation and excitation and charging of phosphor materials.
