LEDS AND ILLUMINATION SpectralLED RS-7-2 calibration light source
Gamma Scientific’s SpectralLED RS-7-2 combines up to four LED light source engines together with a 1m sphere that includes a 300mm output port. The result is a calibration light source that delivers 0.1 per cent radiometric stability and 0.25nm wavelength accuracy for very large area detectors and large field-of-view cameras. The SpectralLED RS-7-2 uses a light engine consisting of 35 discrete LEDs, each having a different centre wavelength, which can be programed on-demand to reproduce the output of illuminant sources such as blackbody, daylight, fluorescent, LED and CIE illuminants, or the spectrum of any illuminant reflected by a target such as a Macbeth or X RITE target.
Cobra MultiSpec LED line light
ProPhotonix’s new multispectral LED line light, the Cobra MultiSpec is available with up to 12 wavelengths, making it ideal for multispectral and hyperspectral imaging applications across a wide range of industries. With discrete control of up to 12 wavelengths, users can maximise contrast by selecting the optimal colour mix and varying the intensity of each wavelength to their specific application need. Available in wavelengths from 365-
The system
can even be swept through wavelengths to simulate a scanning monochromator. The SpectralLED
RS-7-2’s
functionality is accessed through a simple firmware interface, which also contains a detailed calibration matrix for every LED channel. A combination of DC constant current drivers, optical feedback, and thermoelectric cooling maintains high luminance accuracy in real time, without any effort on the part of the user.

1,500nm, the Cobra MultiSpec can be configured with two to twelve wavelengths. ProPhotonix’s use of chip-on-board LED technology ensures that the line light delivers high brightness and excellent uniformity in a compact form factor. The light also offers field adjustable optics,
allowing users to select the optimum lens position for their specific application. Cobra MultiSpec is modular and available in any length up to five metres.

µPAX-2 pulsed xenon light source
Excelitas Technologies debuted its new 2W pulsed xenon light source, the µPAX-2, at Photonics West. The µPAX-2 provides microsecond pulses of broadband light with arc stability to offer a compact solution containing a flash lamp, trigger circuit and power supply in an EMI-suppressant enclosure. Applications for the µPAX-2 include
UV/Vis spectrophotometry, point-of-care analytics, environmental and absorption analysis, fluorescence triggering, immunoassays and microplate readers. The µPAX-2 offers a stability of 1.0 per
cent CV. Its broadband, EMI suppression design minimises electromagnetic interference to provide OEMs with a precision-aligned light source. It offers efficient coupling, high stability and maximum reliability to meet the needs of analytical applications.

SOFTWARE New EasyTau software version ACCESSORIES iXBlue MBC-DG-LAB
Laser Components’ iXBlue MBC-DG-LAB automatic bias controllers lock the operating point of LiNbO3
ensure environmental conditions and stable operation over time. The MBC-DG-LAB controllers are dither
signal-based and therefore superimpose a low amplitude, low frequency tone on LiNbO3 Mach-Zehnder modulation signals. The resulting optical modulation is then detected and a digital signal processing technique, based on a FFT analysis principle, allows the operating point to be locked at the desired position. The controllers are continuously tuneable, allowing operation of the modulator at any point of its transfer function. The new controllers have improved

sensitivity and stability, and introduce an autoset operation for the quad/min/max modes, a graphical user interface, storage and recovery of the user parameters and USB communication. The bias controllers are available as bench- top instruments and OEM boards. They are especially well suited for digital and pulse applications.

PicoQuant has released a new version of its EasyTau software for the fluorescence lifetime spectrometer FluoTime 300. The release focuses on the integration of interfaces allowing remote execution of scripts written in the EasyTau scripting language to control third- party accessories. Another highlight of this release is the optimisation of several EasyTau wizards, most notably the quantum yield wizard which now offers an improved workflow for samples with low quantum yields. Additionally, a new wizard for the measurement of phosphorescence spectra with picosecond pulsed laser excitation is included. These fully user-customisable scripts make it easy to carry out sophisticated spectroscopic experiments. The FluoTime 300 has steady-state and phosphorescence options. EasyTau allows researchers to focus on their samples without having to find the best instrument settings.
