Characteristics of dielectric film Mirrors.
1.The dielectric film reflector is made out of the interference principle of overlapping multilayer films.
2.The reflectivity of the dielectric film reflector is high, which can be close to 100%. The mechanical hardness of the film is high, and resistant to cleaning operations.
3.The reflector of a dielectric film is narrower than a metal film, and is closely related to the angle of incidence.
4.The reflectivity and reflected bandwidth of a dielectric film reflector is influenced by the polarization state of the incident light in addition to the incidence of 0 degrees.
5.A dielectric film reflector can be used for a strong laser, but the damage threshold test is a destructive test.
Optical UV Filter and other filters
Worldhawk can provide precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter (UV filters), Narrow bandpass filter, ND filter, Negative Filter or Notch filters, dichroic, color substrate.
Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.
Custom filters are available for both large manufacturing needs and in prototype volumes. Contact us for more information or to arrange a quote.

Color Glass Filter ( Colored optical glass filters )
Optical color glass can selectively transmit special wavelength of light, or a portion of wavelengths in a continuous spectrum, or reduce transmission evenly across visible spectrum by absorbing or reflecting the portion of the light that is not being transmitted.
Optical color glass is also called Colored optical glass filters. It is mainly used as filters for observing, photograph, infrared instrument in order to improve the visibility or meet special spectrum requirements. It can be also made into colored glasses.
Worldhawk can provide various color glass filters or its substitutes.
include cut-off type glass filter, selective absorption type glass filter, heat-absorbing glass and neutral grey colored glass.
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.
Powell Laser Line Generator Lenses
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.
Powell lens are available with output fan angles of 5°--130°. They are designed for use at 405-900 nm with an input beam diameter of 0.8 -5.0mm (1/e2). Rectangular input beam can be customized for powell lens.
The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
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.
The Powell Lens can be widely used in alignment, machine vision systems, construction and process control fields.
