Sapphire Glass Window for Medical Lens Medical Sapphire Window
Description
The window panel is a kind of parallel plane plate, which is usually used as the protection window of electronic sensor or external environment detector. The window slice does not change the magnification of the system. The substrate materials include various optical glass, K9, ultraviolet fused silica, infrared fused silica and crystal materials such as CaF2, MgF2, ZnSe, GE and Si, and provide various optical coatings such as antireflection coating, high reflection coating, spectroscopic coating and metal coating. Wide band antireflection coatings can be used in ultraviolet, visible, near infrared and mid infrared bands.

As a transparent physical barrier, windows enable light to enter a different environment from one environment. For example, from air to water, or from vacuum to air. Such as different temperature, pressure, chemical composition or cleanness.
The hardness of sapphire is only lower to diamond and it is hard to scratch. Its transmission wavelength ranges from deep ultraviolet to infrared. At present, sapphire is a kind of material widely used, which has the properties of scratch resistance, impact resistance and flexibility. Sapphire has long been used to make watch protective glass or camera lens protective glass cover and filter glass, and now it is widely used to make mobile phone screen. Sapphire glass is composed of colorless synthetic corundum (a mineral produced by alumina AL2O3). In fact, strictly speaking, sapphire is not a kind of glass, because it does not have glass amorphous structure, but a crystal structure.
Sapphire window products can be used as Gan, GaAs and other new materials, integrated circuit substrates, epitaxial and directional substrates, watch glass lens, optical lenses and surface acoustic wave devices; Because sapphire has good light transmittance, its infrared transmittance almost does not change with temperature, so it can be used as infrared window, high temperature furnace observation window, counter window, etc. It ranges from ellipse, oblique disc, step window, oblique disc and so on.
Buying Guides
Customers need to know:
1. The products are made according to the requirements of customers. Please contact us before placing an order to confirm the detailed production process, quantity, production period, logistics and other relevant information.
2. Customization needs to know:
(1) Customization: please directly provide dimensions (length * width * thickness, and color quantity) (please consult customer service quotation).
(2) Product processing: please send drawings to the owner, such as CDR, AI, CAD and other vector drawings, and inform the thickness, (consult customer service quotation) to give you a quotation. No friends can draw by hand and take photos for us. We need drawings for complex processing.
3. Please confirm the size and drawing carefully before photographing. Once processed, it will not be returned or changed.
4. There is a certain tolerance for processing and material thickness. Buyers who require no difference should be merciful! The tolerance is about 0.3mm. Once photographed, we do not accept any return or exchange due to tolerance!
