Notes: (b) For powers up to 50W it is recommewnded to work with the fan off and then the noise level is ~3 times lower. It is also recommended to measure energy with the fan off. Notes: (c) Position accuracy for the central 20mm of the aperture as limited by beam position resolution. Position can be tracked with ±1mm accuracy over central 32mm of the aperture. Accuracy is reduced by a factor of 3 at minimum power. Notes: (d) Assumes laser beam with Gaussian (TEM00) distribution. For other modes, size measurement is relative. Notes: (e) Accuracy spec will be maintained for beams from 6 to 35mm not deviating from center more than 15% of beam diameter. Notes: (f ) Calibrated for ~0.8µm, 1.064µm and 10.6µm Notes: (g) Water temperature range 18-30°C, Water temperature rate of change <1°C/min Notes: (h) Position accuracy for the central 10 mm of the aperture as limited by beam position resolution. 0.5M cable to smart connector 0.5m cable to smart connector 77 (4x) M5x10 deep Mounting Threads 11.3 Absorber Surface DC power supply socket (4x) M4x6 deep Mounting Threads 0.5M cable to smart connector Interface Module on cable (2x) Quick Connect Fitting For 3/8 Plastic Hose 1/4x20 BSW (2x) M3x6 deep 1.5m cable to module 100 Front Side Front Side 75 Rear Side Rear Side For latest updates please visit our website: www.ophiropt.com/photonics
