ZERO ORDER WAVEPLATES - 10mm - Tower Optical - #1

Text version of the page

Tower’s 10mmzero orderwaveplates provide userswith a high performance crystal quartz retarder with a clear aperture of 8 mm. These waveplates are air spaced, having a stainless steel spacer between two crystal quartz plates that form the zero order capability. Zero order waveplates are far less sensitive to temperature variations than mulitple orders. Air spaced waveplates have higher thermal stability and power handling capability than contacted or cemented. There are no failures as occur with contacted waveplates coming apart. Angular alignment of the waveplates is also more accurate. TowerOptical standard 10mmwaveplates aremade fromlaser quality crystal quartz and are AR coated. Each plate is AR coated on both sides. Standard retardations are ½ or ¼ wave. The waveplates are offered either unmounted with a diameter of 10 mm or mounted in a 12.7 mm or 25.4 mm, anodized aluminum mounting ring with an 8mm clear aperture. The standard wavelengths available are shown in the chart below. As a special feature, Tower offers the ability to supply the 10 mm zero order waveplates at wavelengths within a range of 10–20 nm from any of those listed on the chart. Other wavelengths are available on a custom order basis. 4 561-740-2525 • Fax 561-740-2518 sales@TowerOptical.com • www.TowerOptical.com Cage Code: 1N2U3 SDVO-SB ITAR Compliant Zero Order Waveplates–10 mm • 8 mm clear aperture • 10 mm unmounted diameter • 12.7 or 25.4 mm mounted diameter • Wide range of wavelengths • ½ and ¼ wave retardation • Waveplates are AR coated • Very high laser quality • High performance specifications Ordering Information Unmounted Z-10-A-R-N-WL . . . . . . . . . . . . . . . .$275 Mounted in a 12.7 mm ring Z-10-A-R-A-WL . . . . . . . . . . . . . . . .$305 Mounted in a 25.4 mm ring Z-10-A-R-B-WL . . . . . . . . . . . . . . . . .$315 R = Retardation: .500 or .250, WL = Wavelength Standard Wavelengths Waveplate Specifications for 8 mm clear apertures Material: crystal quartz – laser quality Waveplate thickness range: 0.3 to 1.3 mm Wavefront distortion: ë/10 @ 632.8 nm Surface quality: 10-5 Scratch-Dig Parallelism (wedge): 0.5 arc seconds Wavelength range: per table to the right Retardation tolerance: ±0.005 waves @ 632.8 nm Coating: anti reflective, R<0.25% per surface Damage threshold: 1 kW/cm2 –CW,3.5 J/cm2@10 ns Diameter: 10 mm, +0.0/-0.25 mm unmounted; 12.7 or 25.4 mm, +0.00/-0.25 mm mounted Mounted thickness: 6.4 (12.7 mm) or 7.8 (25.4 mm) See Page 13 for Waveplate Ordering Information See Page 8 for Any Wavelength Program 248 266 308 325 355 399 408 413 423 442 458 488 514.5 527 532 556 589 632.8 647 650 660 670 676 694 710 755 767 780 790 795 800 808 810 825 830 850 905 940 980 1047 1053 1064 1112 1310 1319 1550 1570 1980 2020
