100 Fisk Hill Road, Sturbridge, MA 01566 Phone: (774) 230-1939     Email:JBVOPTICAL2@msn.com JBV's High Quality Custom Lenses Custom Precision Plano Cylindrical Lenses JBV supplies UV grade fused silica cylindrical lenses designed for use with excimer and UV laser beams. High efficiency anti-reflection coatings increase transmission performance from 193nm to 438nm. Cylindrical lenses are either plano-convex or plano-concave in form; and rectangular, circular, or square in shape. Other special shapes are available on request. These lenses are used in applications requiring magnification in one dimension only, such as in transforming a point image into a line image, or changing the height of an image without changing the width, or visa-versa. Typical applications include slit and line detector array illumination. PLANO CYLINDRICAL LENS SPECIFICATIONS: < 3 arc minutes [Return to Optics Menu]  [Return to Top of Page] Custom Plano-Convex Lenses   These lenses have positive focal lengths, converge incident light, and form both real and virtual images. They approach best-form for infinite and near infinite conjugate ratios, with the preferred focal plane being that adjacent to the plano surface. JBV supplies custom cutting, coating, edging and complete fabrication. Send us your drawings and specifications or call for a free consultation. PLANO CONVEX LENS SPECIFICATIONS:iety of single wavelength, dichroic and broad band mirror coatings are available from the UV (150nm) through the far infrared.

Custom Bi-Convex Lenses

Like the plano-convex lens, the bi-convex lens has a positive focal length and forms both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, several aberrations nearly cancel at unit conjugate ratio (s=s'=2f). This includes coma, distortion, andop"> [Return to Top of Page] Custom Meniscus Lenses   Meniscus lenses can be designed with a shape that results in no additional spherical aberration or coma being introduced into the system. This shape is called the aplanatic form. It is possible to achieve the aplanatic form only when the lens is operated at a magnification that is numerically equal to the reciprocal of the index of refraction of the material from which it is made. The meniscus lens is most often used in conjunction with another lens to produce a system with a longer or shorter focal length than the original lens. JBV supplies custom cutting, coating, edging and complete fabrication. Send us your drawings and specifications or call for a free consultation. MENentration: 3 arc minutes Coating: A variety of single wavelength, dichroic and broad band mirror coatings are available from the UV (150nm) through the far infrared.

Custom Plano-Concave Lenses

The plano-concave lens offers minimum spherical aberration at negative-infinite or near infinite conjugate ratios, with the concave surface facing the longest conjugate distance. A collimated beam incident on the curved surface will be transformed into a divergent beam emerging from the plane surface. The divergent beam will appear to emerge from a smaller virtual point source than if the plane surface had faced toward the collimated beam. Reversing the rays, a convergent beam is transformed with least additional spherical aberration into a collimated beam if the convergent beam is incident on the plane surface.

PLANO CONCAVE LENS SPECIFICATIONS: Description: Specification: Material: Glass, Quartz, or Exotic. [Return to Optics Menu] [Return to Top of Page] Custom Pinholes   Pinholes are useful in laser technology for spatial filtering, image analysis, and image processing. The pinholes are precision drilled into stainless steel stock. High energy precision pinholes are designed to be used in areas requiring high heat dissipation. The pinholes are fabricated from thin copper sheets which are drilled and black anodized. One surface is coated with gold to reflect the incoming high energy laser radiation.
