13-355nm and 1.06-3000?m - Pyroelectric Array Camera - 1

3.2.2 13-355nm and 1.06-3000µm - Pyroelectric Array Camera PyrocamTM III Series Features ֺ ֺ Spectral ranges available from 13 to 355 nm and 1.06 to >3000 µm ֺ ֺ Image CO2 lasers, telecom NIR lasers and other infrared sources out to Far IR THz sources ֺ ֺ Solid state array camera with 1000:1 linear dynamic range for accurate profiling ֺ ֺ Integrated chopper for CW beams and thermal imaging ֺ ֺ Versatile Firewire interface ֺ ֺ Interchangeable windows available for a variety of applications ֺ ֺ Image Viewer utility presents 3D isometric plots, 2D color contour plots and grayscale, among other views ֺ ֺ Includes BeamGage Laser Beam Analysis Software for extensive quantitative analysis and image display Spiricon has been the world leader in the manufacture of pyroelectric solid-state detector arrays and cameras. For over 25 years the PyrocamTM has been the overwhelming camera of choice for Laser Beam Diagnostics of IR and UV lasers and high temperature thermal imaging. Precision, stability, reliability, and versatility have become its proud heritage. d The PyrocamTM III offers easy Win ows® camera setup, direct Windows quantitative and image display, 14 bit digitizer, versatile Firewire® PC interface, an integral chopper for CW beams and thermal imaging, and many other enhanced features. The PyrocamTM III camera creates clear and illuminating im ges of your laser beam profile. Displayed in 2D a or 3D views, you can immediately recognize beam characteristics that affect laser performance and operation. This instantly alerts you to detrimental laser variations. Instantaneous feedback enables timely correction and real-time tuning of laser parameters. For example, when an industrial shop foreman saw the CO2 laser beam profile in Figure 1 he knew immediately why that laser was not processing materials the same as the other shop lasers, with the profile shown in Figure 2. Fig. 1. Industrial CO2 laser performing inconsistent processing. Fig. 2. Industrial CO2 laser performing specifed processing. Pulsed and CW Lasers 3.2.2 Beam Profile See Your Beam As Never Before The PyrocamTM III measures the beam profile of both pulsed and CW lasers. Since the pyroelectric crystal is an in egrating sensor, pulses t from femtosecond to 12.8ms can be measured. The pyroelectric crystal only measures changes in intensity, and so is relatively immune to ambient tempera ure changes. Because CW laser beams must be chopped to create a changing signal, the PyrocamTM III contains an t integral chopper as an option. 139 For latest updates please visit our website: www.ophiropt.com/photonics 01.01.2012

13-355nm and 1.06-3000?m - Pyroelectric Array Camera - 2

Measuring Terahertz Beam Profiles Spiricon’s PyrocamTM III pyroelectric camera is an excelent tool for measuring THz lasers and l sources. The coating of the crystal absorbs all wavelengths including 1µm to over 3000µm (0.1THz to 300THz). For THz sources the sensitivty of the PyrocamTM III is relatively low, at about i 300mW/cm2 at full output. With a S/N of 1000, beams of 30mW/cm2 are easily visible. In ad ition, with Spiricon’s patented Ultracal baseline setting, multiple frames can be summed to d “pull” a signal out of the noise. Summing 256 frames enables viewing of beams as low as...

Windows® PC Interface The PyrocamTM III Windows application incorporates setup software to control all functions of the camera, such as pulsed versus chopped operation, gain, and background reference subtraction, eliminating all controls from the camera housing. Windows Image Viewer A Windows viewer application enables viewing of the laser beam in a number of modes, including 3D isometric plots, 2D color contour plots, and gray scale for thermal imaging. This application enables stand-alone operation of the camera independent of any other software. Nevertheless, the Spiricon BeamGage beam...

13-355nm and 1.06-3000?m - Pyroelectric Array Camera - 4

State-Of-The-Art Electronics The camera features a 14 bit A/D converter which digitizes deep into the camera noise. This enables reliable measurement and analysis of both large signals and low level signals in the wings of the laser beam. Fourteen bit digitizing also enables accurate signal summing and averagng to pull weak signals out of noise. This is especially useful with fiber optics at 1.3µm and 1.55µm, and in thermal imagng. i i The PyrocamTM III camera electronics incorporates 2 Firewire® (IEEE 1394A) interface ports. Multiple Pyrocam IIIs can be daisy chained together using the...

13-355nm and 1.06-3000?m - Pyroelectric Array Camera - 5

The PyrocamTM III is becoming an essential tool in the maintenance of industrial infrared lasers, especially CO2. The PyrocamTM III replaces non-electronic mode burns and acrylic blocks by providing higher definition electronic recording of data, and analysis of short term fluctuations. The PyrocamTM III is superior to other electronic methods of measuring CO2 lasers because the entire beam can be measured in a single pulse, and additional measurements made in real-time. This ensures that the beam did not change during the measurement. Detector Damage Threshold The PyrocamTM III sensor is...
