The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
Worldhawk are professional supplier for powell lens, in fact, we have already become the one of the main important suppliers of powell lenses in China. cooperation with us , you will get high quality products with reasonable price and products performance at the same time
These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.

Optical sapphire ball lens and half ball lens are both made from Al203,
it's ideal for demanding applications (such as laser systems).
They have a lot of advantages:
1/ Stronger than standard optical glass,they have extreme surface hardness, high thermal conductivity, high dielectric constant and
resistance to common chemical acids and alkalis.
2/ Transmits Wavelengths Ranging From UV to Mid-Infrared (0.2 - 5.5µm.)

About sapphire materials for our ball lenses
We only choose the best sapphire material to process the ball lens and hemispherical half ball lenses for our customers. As you know, sapphire has higher performance and higher purity near the center in the process of growing.
So only the ball lens made from this part of the material has better performance.
Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, Solar-photovoltaic and fiber-to-detector coupling.
Worldhawk can provide spherical ball lenses and half ball lenses in a range of substrates for performance in the ultraviolet to the NIR. Such as including H-K9L(N-BK7), Sapphire, CaF2, BaF2, ZnSe or custom materials upon request.
Ball lenses feature short back focal lengths to minimize the distance needed from the ball Lens to the optical fiber. Ball lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications.
Half-Ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy, microscopy, optical pick-up devices,and laser measurement systems.
The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
