QUANTEL EVERGREEN BIG SKY LASER SERIES KEY FUNCTIONS & APPLICATIONS:

QUANTEL EVERGREEN BIG SKY LASER SERIES PART NO: 00249000 SERIAL NO: 14072404 REVISION: A. MANUFACTURED: AUGUST/2014 1000 VA WITH LAZER HEAD EVERGREEN BIG SKY LASER SERIES CLASS 4 LASER PART NO: 00248300-2 SERIAL NO: 1407250130 LAMP-PUMPED ND:YAG LASER SYSTEM MANUFACTURED BY QUANTEL LASER (BY LUMIBIRD). IT IS SPECIFICALLY ENGINEERED AS A DUAL-CAVITY FLUID ILLUMINATION SOURCE FOR PARTICLE IMAGE VELOCIMETRY (PIV) AND LASER INDUCED FLUORESCENCE (LIF) RESEARCH. CORE SPECIFICATIONS: PART NUMBER: EVG00200 REPETITION RATE: 15 HZ PULSE WIDTH: 10 NS COOLING SYSTEM: LIQUID-TO-AIR HEAT EXCHANGER UTILIZING DISTILLED WATER. INCLUDES A LAVISION PTU X VZ-TRIGGER PTU X STANDARD EXTERN SERIAL NO: VZ21-0589 LAVISION PTU X OVERVIEW: FUNCTION: THE LAVISION PROGRAMMABLE TIMING UNIT (PTU) X IS A UNIVERSAL TIMING AND HARDWARE SYNCHRONIZATION HUB. CONTROL: IT GENERATES HIGH-PRECISION TRIGGER PULSES (IN STEPS AS SHORT AS 10 NS WITH ULTRA-LOW JITTER) MANAGED DIRECTLY VIA DAVIS SOFTWARE. CAPABILITIES: IT COORDINATES TIMING FOR SINGLE/DUAL-FRAME CAMERAS HIGH-SPEED/LOW-SPEED SETUPS AND PULSED LASERS. ALSO INCLUDES SINPRO SWITCHING POWER SUPPLY 1.9 AMPS AND ALSO INCLUDES LAVISION VZ-ILLUMINATION HIGH EFF DIFFUSER ARTICLE: 1108417 SERIAL NO: VZ14-0116. THE LAVISION VZ-ILLUMINATION HIGH EFFICIENCY DIFFUSER IS A SPECIALIZED OPTICAL COMPONENT MANUFACTURED BY LAVISION. IT IS DESIGNED TO OPTIMIZE LASER LIGHT SOURCES USED IN ADVANCED IMAGING APPLICATIONS LIKE PARTICLE SIZING SPRAY ANALYSIS AND FLUID MECHANICS. KEY FUNCTIONS & APPLICATIONS: SPECKLE-FREE ILLUMINATION: COHERENT LASER LIGHT INHERENTLY PRODUCES A GRAINY "SPECKLE" PATTERN THAT DEGRADES IMAGE QUALITY. THIS HIGH-EFFICIENCY DIFFUSER CONVERTS RAW LASER LIGHT INTO A HOMOGENEOUS SPECKLE-FREE BACKLIGHT. HIGH-SPEED IMAGING: BY SHAPING AND UNIFORMING THE LIGHT FIELD FROM SHORT-PULSE OR DOUBLE-PULSE LASERS IT ALLOWS CAMERAS TO CAPTURE CRISP SHADOWGRAPHS OF TINY FAST-MOVING PARTICLES (DOWN TO THE MICRO-SCALE) WITHOUT MOTION BLUR. THIS IS A HIGHLY SPECIALIZED RESEARCH-GRADE PARTICLE IMAGE VELOCIMETRY (PIV) AND LASER INDUCED FLUORESCENCE (LIF) FLUID MECHANICS IMAGING BUNDLE. BASED ON THE EXPLICIT HARDWARE SPECIFICATIONS PROVIDED HERE IS A STRUCTURED BREAKDOWN OF THE COMPONENTS THEIR EXACT ROLES AND HOW THEY INTEGRATE INTO A COMPLETE SCIENTIFIC EXPERIMENTAL SETUP. COMPONENT BREAKDOWN: 1. LASER SYSTEM: QUANTEL (LUMIBIRD) EVERGREEN DUAL-PULSE ND:YAG ROLE: THE CORE ILLUMINATION SOURCE. BECAUSE FLUID DYNAMICS REQUIRE CAPTURING EXTREMELY FAST-MOVING PARTICLES AT DISTINCT PRECISE INTERVALS A SINGLE-CAVITY LASER WON'T SUFFICE. THIS SYSTEM CONTAINS A DUAL-CAVITY DESIGN ALLOWING IT TO FIRE TWO IDENTICAL HIGH-ENERGY LASER PULSES WITH AN INCREDIBLY SHORT MICROSECOND-SCALE DELAY BETWEEN THEM. OUTPUT: GENERATES A 532 NM GREEN LIGHT AT 200 MJ PER PULSE WHICH IS OPTIMAL FOR EXCITING FLUORESCENT TRACER DYES AND SCATTERING LIGHT OFF SEEDING PARTICLES IN FLUID. THERMAL MANAGEMENT: UTILIZES A DEDICATED LIQUID-TO-AIR INTERNAL HEAT EXCHANGER THAT RELIES STRICTLY ON DISTILLED WATER TO MAINTAIN STABLE CRYSTALLINE TEMPERATURES DURING 15 HZ OPERATIONS. 2. SYNCHRONIZATION HUB: LAVISION PROGRAMMABLE TIMING UNIT (PTU) X THE TIMING BETWEEN THE TWO LASER PULSES AND THE EXPOSURE FRAMES OF THE CAMERA MUST BE PERFECTLY LOCKED DOWN TO THE NANOSECOND. CAPABILITY: IT HANDLES EXTERNAL TRIGGERING (VIA THE VZ-TRIGGER MODULE) WITH 10 NS STEP RESOLUTION AND ULTRA-LOW JITTER. IT FORCES THE CAMERA'S SHUTTER TO CAPTURE FRAME A EXACTLY AS LASER PULSE A FIRES AND FRAME B EXACTLY AS LASER PULSE B FIRES. SOFTWARE TIE-IN: IT IS COMPLETELY DEPENDENT ON AND CONTROLLED BY LAVISION'S PROPRIETARY DAVIS SOFTWARE SUITE. NOT INCLUDED 3. OPTICAL CONDITIONING: LAVISION VZ-ILLUMINATION HIGH-EFFICIENCY DIFFUSER ROLE: HOMOGENIZES THE RAW VOLATILE LASER BEAM. COHERENT LASER LIGHT NATURALLY CREATES "SPECKLE PATTERNS" (GRAINY INTERFERENCE) WHEN BOUNCED OFF OBJECTS WHICH DESTROYS DATA QUALITY WHEN TRYING TO TRACK MICROSCOPIC FLUID PARTICLES. APPLICATION: IT ELIMINATES LASER SPECKLE AND SHAPES THE BEAM INTO A UNIFORM SMOOTH BACKLIGHT. THIS ALLOWS HIGH-SPEED CAMERAS TO RECORD CLEAN SHADOWGRAPHS OR LIGHT SHEETS OF MICRO-SCALE PARTICLES AND FAST SPRAY DYNAMICS WITHOUT MOTION BLUR. 4. AUXILIARY POWER: SINPRO SPU65-201 SWITCHING POWER SUPPLY ROLE: PROVIDES A CLEAN REGULATED 65W MAX DC POWER SOURCE LIKELY DEDICATED TO RUNNING THE LOW-VOLTAGE INTERNAL ELECTRONICS OF THE LAVISION PTU X TIMING HUB OR AUXILIARY SENSOR MODULES
