Spectroscopy Stray light correction tool
Instrument Systems now offers stray light correction during calibration of array spectrometers. By including a stray light correction matrix in the calibration process, it is possible to suppress the stray light during measurement by an order of magnitude down to 10-5
.
A 10 per cent higher sensitivity in the UV range after stray light corrected calibration leads to about 3-4 per cent higher accuracy in the radiometric measurement. The more accurate determination of the radiometric values of UV LEDs facilitates their characterisation and development, and supports the various applications of these radiation sources, for example, in the field of coating, curing, disinfection or biomedicine. In determining the x, y colour coordinates of white and coloured LEDs, stray light corrected devices from Instrument Systems achieve an improvement in the measurement accuracy of high-quality array spectrometers, between 0.0015 and 0.0020. For evaluating photobiological safety, particularly the blue light hazard of the human eye, stray light corrected array spectrometers provide a suitable and cost effective alternative to monochromators.

Model 248/310
McPherson’s grazing incidence wavelength dispersive optical spectrometer allows rapid analysis of spectral light in the ~1 to 300nm wavelength region (4 to 1,200 eV.) Beside high- harmonic laser generation experiments, the Model 248/310 is also useful for measuring ion or discharge light sources and astrophysics detector calibration. McPherson instruments are essential in many and related research endeavours. Experimental fusion reactors around the world employ McPherson XUV spectrometers too.
Space scientists and plasma physicists who need an instrument for vacuum ultraviolet, EUV, and XUV capitalise on the McPherson
Eagle Raman-S spectrometer
Ibsen Photonics has announced the new Eagle Raman-S spectrometer platform for OEM supply to manufacturers of analytical instruments.
The Eagle platform consists of high throughput, robust and high resolution spectrometers, suited to OEM integration into weak intensity Raman solutions at
248/310 spectrometers range and flexibility. Configured in reverse, it operates as a tunable light source. This is useful for spectral calibration and spectroscopy in the vacuum ultraviolet and the extreme and soft x-ray wavelength region (EUV and SXR respectively). Direct detection CCDs, image intensifiers, microchannel plates, or electron multipliers provide wide range and flexible detection.
The Model 248/310 ships completely assembled and tested for spectral-resolution and with vacuum leak test certification. Adapters, differential pumping, and grazing incidence collection optics to connect more easily to the experiment can be included too.

785 or 830nm excitation. It combines high resolution with high sensitivity and flexibility in choice of detector system. Due to its robustness and thermally stable operation, the Eagle Raman-S spectrometer is particularly well suited to industrial process control instruments. The spectrometer provides a low stray light level and high efficiency due to the use
of Ibsen Photonics’ in-house produced wide bandwidth transmission gratings. Optical resolution can be as good as 4cm-1
and the
wavelength range of 800–1,100nm enables 200–3,650cm-1
Raman range with a 785nm
laser. Eagle Raman-S series can be equipped with either a -10°C cooled BT-CCD or a -60°C LDC-DD cooled camera.
