BK7 precise polished ball and half ball lens

1. What’s the Ball Lenses?

Ball lenses are highly transparent spheres made of optical glasses. They are used to focus light into fibers as in diode laser-to-fiber coupling as well as fiber-to-fiber coupling. They have high coupling efficiency and should be much easier to align than traditional lenses due to their physical shape. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.

2. What are the ball lenses used for?

Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy, bar code scanning and sensor applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber.

Features:

· Can be Used as Fiber Coupling Spheres or Collimating Lenses

· Ideal Pre-Forms for Aspheric Lenses

· Available in a Variety of Sizes

Product application introduction:
◇Sapphire Glass Dome Lens Cover and H-K9L Domes Lens Cover are ideal for commercial applications requiring a protective boundary between two environments. Performing as windows, these N-BK7 glass domes allow you to easily protect electronic sensors or detectors without sacrificing field of view. Glass Domes offer superior optical characteristics.
◇Fused Silica Ball lens/Fused Silica Half Ball lens is ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra; High Index Ball Lens/High Index Half Ball lens provide for a shorter back focal length, simplifying fiber coupling, due to the high index of refraction; Sapphire ball lens/Sapphire Half Ball lens and Ruby ball lens/Ruby Half Ball lens are both made from Al203. Sapphire features a high index of refraction and excellent broadband transmission characteristics. Ruby half-ball lenses are easier to see and therefore easier to handle for physical applications.
◇When using First Surface Mirrors, the coated surface is to be facing the incident light in order to minimize energy loss by not allowing light to pass through the glass substrate. The mirrors are available in circular, square, and rectangular dimensions. Rectangular first surface mirrors are ideal for applications requiring the Mirror to be mounted at 45° in order to produce a 90° bend in the light path.
◇Right Angle Mirrors are available with enhanced aluminum, protected gold, or protected silver coatings. Right angle mirrors reflect incident light at 90°, are easily mounted, and are crucial in many optical systems. These mirrors are ideal for applications requiring precision alignment and high performance.
