VY Optoelectronics Co., Ltd.  

Product Name: Optical Low-Order Waveplate Supplier Model NO.: WLOW001 Dia. 25.4mm: 1 Inch Trademark: VY or OEM Transport Package: As Requested Specification: RoHS Origin: China HS Code: 9001909090 Product Description >> Product Description Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. Low-Order Waveplates are much better than the multi-order wave-plates because of its thinner thickness (less than 0.5 mm). Better temperature (38), Wavelength (1.5nm) and incident angle (4.5° )bandwidth and high damage threshold make it widely used in common application.>> SpecificationSpecification of our low-order waveplate as follow:*Material: Crystal Quartz*Dimension Tolerance: +0.0, -0.1mm*Optical Angle Orientation Tolerance: +/-0.1degree*Wavefront Distortion: Λ/8@632.8nm*Retardation Tolerance: <λ/500*Wavelength Range: 240-2100nm*Parallelism<5 arc seconds*Clear Aperture. >80%*Surface Quality: 20-10 scratch and dig*AR/AR Coating: R<0.2% at central wavelength*Other wavelengths, sizes and coatings are available upon requestRange of diameterDia.0.7mm-Dia.400mmRange of curve radiusR1.5-R∞ etc.Tolerance of diameter+/-0.1, +/-0.01, +/-0.005 etc.Surface accuracyλ , 1/2λ , 1/4λ , 1/10λ etc.Tolerance of Thickness+/-0.1, +/-0.05, +/-0.01 etc.Centration+/-2′,+/-1′ etc.Aperture N5, 1 etc.Irregularity ΔN2, 1, 0.5, 0.2 etc.Surface quality60/40, 40/20, 20/10, 10/5 etc.>> Company Introduction>>Related Products VY Optics could also manufacture and design other optical elements, includingachromatic lens,dome lens,filter,prism,ball lens,cylindrical lens,optical mirrors,spherical lensandrod lens, we can fabricatehigh-precision lensas per your requested.>>FAQQ:Do you provide samples?
