Camera Selection GuideLaser Beam DiagnosticsOptical Telecom Analysis

Spiricon’s innovative and exclusive LBA hardware and software design allows

interface to many different camera types. This allows you to have the camera that works best for your individual application. The Laser Beam Analyzer interfaces to RS-170, CCIR, digital, FireWire, and USB2.We provide the following selection guide and chart to assist you in the choice of a camera, or cameras, that best meet your needs. In addition to the specification chart, we have provided a small applications recommendation chart to assist in this decision.

The majority of the specifications in the enclosed tables are taken directly from the camera manufacturer’s data. Therefore, we assume no responsibility for the accuracy of this data. We have converted the manu-facturer’s sensitivity data from photometric units specified in foot candles to radiomet-ric units of watts per square centimeter and

joules per square centimeter, for the conve-nience of laser users. This conversion is an approximation, and is very wavelength dependent.

Please note that any of these cameras listed, as well as many others, can be immediately interfaced to the LBA-PC. Because of Spiricon’s exclusive Ultracal™ (patented) function, you can switch at will from one camera to another. This is in contrast to other beam diagnostics manu-facturers that claim interfacability to many cameras, but fail to tell you that the instru-ment must be returned to the factory to be re-calibrated for each camera change.

Spiricon engineers are constantly working to be the industry’s best supplier of beam diagnostic instrumentation. Achieving the unparalleled satisfaction of our customers is our greatest source of pride and gratification.

The following are observations relative to the various cameras available to enable you to make the best possible selection for your application. The notes below are coupled to the numbers in parenthesis at each point of the selection chart.Please note that cameras purchased from Spiricon for use with the Laser Beam Analyzer include special alignment and option features. These features add increased cost over the list price of a basic camera. For the majority of laser beam diagnostic applications these options are essential for accurate and reliable operation. These include such options as: windowless detector to eliminate fringe patterns, low noise electronics, extended frame integration, special synchronization timing, etc.

Notes To Camera Selection Guide

(1) The cameras described in this comparison are available with many factory options which are too numerous to detail on this chart. The information contained herein is general in nature and is not an assurance that any camera not purchased through Spiricon will operate as recommended.

(2) Refers to the maximum beam dimension that can be dis-played on the Laser Beam Analyzer in lowest magnification.

(3) In normal (non-shuttered) camera operation, this is the fast-est rate at which the laser may pulse and the camera can still separate one pulse from the next. It is not the rate at which the Beam Analyzer can acquire pulsed data. With electronic shutter operation, (see note 4) higher rate laser pulses can be split out by matching the laser repetition rate to the shutter speed.

(4) Various shutter speeds and options are available with different makes and models. Consult manufacturer specifications.

(5) Signal to Noise Ratio measured with the LBA-PC using the Histogram of background noise.

(6) With pulsed lasers, the Interlaced Frame Transfer style cam-era will capture single laser pulses in only one field thus having the effect of reducing the stated camera resolution by 1/2.

(7) CCD cameras function at wavelengths as short as 190nm. However wavelengths shorter than 248nm will damage the cam-era sensor and lead to camera failure.

(8) This is the value specified when supplied with a low noise factory option.

(9) These Interline Transfer cameras offer the highest resolution with pulsed lasers because they output the pulse in both fields.

(10) The TM-6/7, cameras have been observed to create a ghost image when operating with pulsed YAG lasers at 1064 nm. There-fore, we recommend the COHU 4812 and the SMD-1M15 for this wavelength and pulse condition.

(11) These cameras are not available with remote heads, but are already so small that they are approximately equivalent in size to other cameras which have separate remote heads.

(12) The FireWire® camera maximum rate depends on the ROI (Region of Interest) size, the bits readout, and the number of cameras on the same bus. The SCOR20 operates at 7.5Hz@12 bits and 15Hz@8 bits. It operates up to at least 25Hz with a smaller ROI. It slows down to 3.75Hz with 2 cameras on the same FireWire® bus. However, up to 3 FireWire® to PCI cards have been installed in one desktop computer and have operated 3 cameras simultaneously without slowing down the rate. Performance also depends on the speed of the computer.

(13) S/N given is with camera in natural state of g =1. With g changed to 1.95 in the LBA-PC to compensate for the phosphor non-linearity, the noise is raised and the S/N becomes about 30dB.

(19) For CW Uses chopper, Camera model PY-III-C.

(21) The LBA-PC digitizes analog cameras at the vertical pixel pitch in both horizontal and vertical axes. A video low pass filter in the camera enables digitizing the horizontal pixels at a pitch dif-ferent the actual pixel pitch. This creates a square digitized pixel.

(22) These cameras require an optional synchronous chopper to operate in CW mode.

(23) These cameras are supplied with AR coated windows. Con-tact factory for details of coatings.

(25) The SU-320M now has a baseline above zero so it is now possible to UltraCal the camera and obtain accurate beam width measurements.

(26) The COHU 4812 is the one CCD camera that has response to 1310nm without blooming, even though the responsivity is greatly reduced.

(27) The FireWire and USB2 cameras work well with short pulse YAG lasers when the external trigger module is used to trigger the camera synchronous with the laser.
