UV Bandpass Filters

Description

Introduction of Bote UV Bandpass Filters

A UV bandpass filter is a filter that transmits UV rays and blocks other wavelengths of light. These filters are widely used in scientific, industrial and medical fields. The light transmittance of UV bandpass filters is generally 15-30%. Most UV bandpass filters cannot have high transparency due to material reasons.

But the core function of a UV bandpass filter is the ability to isolate specific UV wavelengths, which is useful in a variety of applications, from forensic analysis to sterilization processes.

UV bandpass filters typically cover the UV spectrum from about 200nm to 400nm. Here are some common ranges of this UV spectrum:

• UV-A: 315 ~ 400nm. This range is commonly used in forensic analysis applications.
• UV-B: 280 ~ 315 nm. This range of filters is used for medical, environmental, and water quality testing.
• UV-C: 100 ~ 280 nm. It is widely used for sterilization, especially around 254 nanometers, which has a strong sterilization effect

How to Choose the right UV Bandpass Filters?

When choosing a UV bandpass filter, you can decide which type of filter to choose by considering the following points:

• Choose a filter with a center wavelength that matches your application needs.
• High transmittance filters provide brighter, clearer images.
• Make sure the filter effectively blocks non-UV light.
• Choose filters that are resistant to UV degradation and have high surface quality.
• Just make sure the filter size is compatible with your device.
• Consider selecting filters that can withstand the extreme conditions of your work environment.
• Choose the best filter within your budget and consider supply chain factors
