Sapphire Step Window
As a optical component manufacturer, we provide Step optical windows and can custom make them to additional shapes with AR coatings. What kinds of optical coatings we can provide for step windows? Contact us for help determining the minimum thickness needed for your pressure of vacuum window.
Optical glass step windows are a specialty of VY Optoelectronics Co.,Ltd.. Step windows, T-Windows are excellent for use in viewports, pressure, and vacuum situations. Sapphire glass step windows also make great viewports for deep ocean vehicles. Sapphire pressure windows stand up well to the abusive salt water and debris while being less thick than other traditional glass counterparts.
Optical windows used in high pressure situations have plenty to gain by losing a lot of thickness. Sapphire optical windows can be up to 65% thinner than Fused Silica windows, while also being much more scratch resistant. We will help you determine the thickness needed to start utilizing sapphire in your project.
VY Optoelectronics Co.,Ltd. can supply high quality "T-STEP" type optical windows which are made of optical glass, optical crystal and laser crystal.
All of these customized windows are desighed to be used in precision optical and Infrared laser systems. The optical transmission is high with little or no distortion of the transmitted beam. The circumference is ground and both edges are no-chips beveled.
Round sapphire optical components are typically the most economical. Rectangular windows can also be made, but usually have to be cut out of round stock. VY Optoelectronics Co.,Ltd. has the machines needed to create any custom shaped windows as well.
Common Specifications of "T-STEP" Type Windows Specifications/Grade Precision Standard Diameter Dia.1.00mm to 400mm customized available Thickness 0.30mm to 50mm customized available Diameter Tolerance +/-0.005mm 0/-0.1mm Thickness Tolerance +/-0.01mm +/-0.05mm Edge Ground Ground Chamfer/Bevel 0.25*45° 0.25*45° Flatness 1/10 lambda per inch @633nm 1/2 lambda per inch @633nm Parallelism 30 arc sec 30 arc min Surface Quality 10/5 60/40 Clear Aperture >95% 85% Coating Customized available Customized available Material BK7, sapphire, fused silica, quartz, Pyrex, BOROFLOAT, float glass, etc.
What is Step windows?
Step windows are either windows or plates ground with a step into the edge or length of the glass. Most of the time, it is produced and processed according to the customer’s design.
What are the uses of step windows?
Step windows are excellent for use in view ports, pressure, and vacuum situations, it can be produced to create step ground or angled cones to good for assembly and handing.
What material is used for Step windows?
Step windows is a protect element in an optical system in the most time, it need to consider the optical performance, chemical properties, physical properties, thermal performance and cost. Common materials suitable for step windows including N-BK7 (H-K9L), Fused Quartz, Borosilicate and Sapphire and so on.
What parameters do we need to consider of Step windows when designing?
1) Materials - Choose the most suitable material, as mentioned in the previous paragraph.
2) Shape - Common shapes include round, square, rectangular. But Round step windows are typically the most economical.
3) Chamfer - In addition to considering remove chips and protection chamfer, it also need to consider of inner groove chamfer
4) Thickness - Determining the Minimum thickness needed for your pressure of step window, Optical windows plenty to gain by losing a lot of thickness.
Same as optical windows, the commonly used coatings are antireflection coating (AR). We supply a range of Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
As a optical component manufacturer, we provide Step optical windows and can custom make them to additional shapes with AR coatings.
