Product Name: Sapphire Glass Meniscus Cylindrical Lens for Optical Instrument Model NO.: vy020 Coating: as Requested Customized: Customized Certification: RoHS, ISO9001 Lenses Color: Clear Material: Optical Glass Shape: Cylindrical Shaped Lens Transmittance: >95% Type: Concave Lens Usage: Lighting, Medical, Optical, Photography Dia. 25.4mm: 1 Inch Trademark: VY or OEM Transport Package: as Requested Specification: RoHS Origin: Cn HS Code: 9001909090 Product Description Product DescriptionMeniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.Specifiction of our meniscus lens as follow:*Material BK7 or other optical materials*Dimension Tolerance +0.0~-0.1mm*Center Thickness +/-0.1mm*Focal Length Tolerance+/-1%*Surface Quality:40/20*Surface Figure:lambda/2 at 633nm on plano side*Clear Aperture >90%*Chamfer 0.25mm at 45 degree typical*Coating OptionalRange 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.Who are we?VY Optoelectronics Co., Ltd, established in 2010 in Optical City of China - Changchun.
