Cylindrical lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either plano concave or plano convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.Plano-convex cylindrical lens,plano-concave cylindrical lens,bi-convex cylindrical lens,bi-concave cylindrical lens,meniscus cylindrical lens,long cylindrical lens,special cylindrical lens etc..Specifiction of our cylinderical 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:20/10 *Surface Figure lambda/2 at 633nm on plano side *Clear Aperture >90%*Chamfer 0.25mm at 45 degree typical *Coating Optional
Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.Sp
Telephoto lens has a narrower angle of view,it thus gives apparent magnification to objects,it also seems to compress distant things, and there is less depth of field. The most obvious is to allow pho
Lithium Niobate(LiNbO3) Crystal lens is widely used as frequency doublers for wavelength > 1 mm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices
Projection lens for medical equipment,pocket projectorWe manufacture and design kinds of projector lens as requirement,not only include short focal length fisheye lens/wide angle lens for Sanyo/Sony p
Beamsplitter Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces. The cemented face of one prism is coated. Before cementing, with a met
Rhombic Prisms are used to display a beam laterally without changing it is direction. They maybe coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coate
Half-ball (hemispherical) lens are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.Specification of half ball lens as
Rectangular prisms are used to deflect a beam of light through 90 or 180 degrees. This can be used as component to create various optical devices. BK-7 can be used for a range between the visible and
Wide angle lenses are great for capturing the expanse of a mountain view, or for giving one an appreciation of the entirety of an organism's habitate. Specification of our wide angle lens as
