Ultraviolet UV Filter Optics

What is Ultraviolet UV Filter

Ultraviolet UV filter is an optical component which is used for selectively allowing or blocking ultraviolet wavelengths of light.

It helps absorb ultraviolet rays and also contributes to the blue polarization of sunlight.

Through precise spectral design and coating processes, it can effectively block ultraviolet light within the range of 200-400 nm, while ensuring high transmittance of visible light or infrared light.

Ultraviolet filters play a significant role in scientific research, industrial production, and optical imaging.

The material of ultraviolet filters

• Optical glass:

High transmittance, resistant to high temperatures, good chemical stability.

• Sapphire crystal:

High hardness, suitable for use in harsh environments.

• Coating process:

People can choose multi-layer medium coating or other coating to enhance the durability of the filter.

 

Advantages of Ultraviolet UV filters

• Precise spectral control:

The ultraviolet UV filter can absorb ultraviolet rays as needed, block or allow certain wavelength bands to pass through.

• High transmittance and low loss:

Based on the inherent characteristics of the ultraviolet filter, it can effectively ensure signal strength and imaging quality.

• High temperature resistance and corrosion resistance:

It can be used to protect the lens components from the influence of the environment.

And the filter is uitable for long-term operation under high-intensity light sources.

• Various sizes and customization:

Chenyu can customize different types of Ultraviolet UV filters. We employ advanced manufacturing techniques and can design according to the user’s requirements.

We can also design based on the content of the drawings. Please feel free to inquire.
