For experiments of bending process of PMP samples used different radiation sources as (a) High Power LED, (b) Laser Diode Red integrated module, (c) Halogen light source.
1. The high power LED (Figure 1) with the parameters of the labels as below
LED Output Power
1240 nW / 1780 mW
Figure 1: Example with the high power LED
2. Laser Diode with wavelength / red colour (635 nm) as integrated module with supplying unit (Figure 2). It was efficient as bending light sources selected for our experiments with good results which allowed us to perform very good bending process of PMP samples based on the of light sources having the technical parameters of the following table.
4.9 – 5.2 V
635.6 nm spectrum
Figure 2: Example with a laser Diode at 635 nm
3. Halogen light source (Figure 3). The bending of PMP samples successfully performed by using as the third light source the halogen bulbs with the parameters of the table hereafter.
Figure 3: Example with the Halogen light source.
The experimental results of several light sources for bending the PMP samples will give the possibility to select the most valuable technical solution for bending/relaxing operations of PMP samples to be further implemented into wave selector/spectrometer devices under development and manufacturing works. We considered the individual light sources parameters, dimensional characteristics and assembling requirements, and weight of the simple supply unit as the main factors to select the most suitable light sources.
The selected solution will allow us to apply it for further development of instrumentation for spectral analysis on the specific instrumentation market.
