Sapphire Tubes Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.

Sapphire Dome Dome windows are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows.   BK7 dome is used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.    UV fused silica glass dome: For applications operating in the deeper UV range, Worldhawk offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures. Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.

Optical Shortpass Filter Worldhawk can provide precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter, 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 to arrange a quote. Cut Off filters  - Dichroic Filter - Longpass Edge Filters   ( Long pass Filters) - Shortpass Edge Filters   ( short pass Filters) - IR Cut Filters   ( IR-CUT Filter) - UV-IR Cut Off Filters   Longpass Filters transmit wavelengths greater than the cut-on wavelength, while Shortpass Filters transmit wave-  lengths shorter than the cut-off wavelength. Dichroic filters perform the same function, while guaranteeing that the  rejected wavelengths are reflected. Any of these filters can be designed for 0  or 45  angle of incidence. Edge and Di- chroic Filters are commonly used in Fluorescence instrumentation, Heat Rejection Applications, and as Color Filters.  While somewhat angle sensitive, they are more forgiving than bandpass interference filters.  Shortpass Edge Filters Transmission UV, reflection IR Material:BK7 upon request Transmission:>90% Blocking:OD3-OD6 Incidence Angle:0°±5°or 45°±5° Surface Quality:20-10 Clear Aperture:>90%

Optical windows are used to allow optical radiation to pass from one environment to another without allowing other elements of these environments to mix. And it does not change the wavelength distribution of the beam, the transmitted wave front, nor does it scatter any of the light out of the beam. An Optical Window is an optically flat. These regular windows are applied to isolate different physical environments while allowing light pass. When selecting windows,please consider materials, transmission, scattering, parallelism and resistance to certain environment. It can be widely used on laser technology, IR detector and imaging technology etc. Worldhawk offers standard and high precision optical glass windows in round ,rectangular, wedge windows and custom shape and size with different optical glasses,Fused Silica, Sapphire, ZnSe, Zns and IR crystal. The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of λ/20. Single layer or multi-layer anti-reflection coatings are available.   Specification of Optical Wndows Diameter  0.2-300mm Diameter tolerance  +/-0.1mm or +/-0.02mm Thickness  0.10-100mm Thickness tolerance  ± 0.1mm or +/-0.02mm Surface quality (scratch & dig)  60/40, 40/20 or better Surface accuracy  λ/10, λ/2, λ Clear Aperture  >85%, >90% Parallelism  +/-3' ,+/-30'' Bevel  0.1~0.3mm×45 degree coating  AR, BBAR or upon customer request( UV, VIS, IR)

IR Bandpass 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.   Bandpass fIlters - Bandpass filters - Narrow bandpass filter - UV bandpass filter - IR Bandpass filter Technique Data:  FWHM: 30nm-80nm OD:2-3 FWHM: 5nm-25nm OD:4-6 Size: φ6-φ200 Center Wavelength Range:340-1064nm (340 380 405 450 492 510 546 578 600 620 630 808 850 940 1064...)    

Optical Glass Longpass Filter  Worldhawk can provide precision filters for many applications, including bandpass interference filter, Cut off filters, UV bandpass filter, 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.

Cut Off filters  - Dichroic Filter - Longpass Edge Filters   ( Long pass Filters) - Shortpass Edge Filters   ( short pass Filters) - IR Cut Filters   ( IR-CUT Filter) - UV-IR Cut Off Filters   Longpass Filters transmit wavelengths greater than the cut-on wavelength, while Shortpass Filters transmit wave-  lengths shorter than the cut-off wavelength. Dichroic filters perform the same function, while guaranteeing that the  rejected wavelengths are reflected. Any of these filters can be designed for 0  or 45  angle of incidence. Edge and Di- chroic Filters are commonly used in Fluorescence instrumentation, Heat Rejection Applications, and as Color Filters.  While somewhat angle sensitive, they are more forgiving than bandpass interference filters.    UV IR Cut is a specialized filters that has the ability to cut both UV rays below 400nm and IR rays above 680mn leaving just the light rays in the visible spectrum passing through the filter and into the camera.This filter is used on a digital camera and the video    350-405nm:Tavg<10% 415±10nm:T=50% 430-630nm:T>85%, Tavg>90% 650±10nm:T=50% 700-1100nm:T<3%
