Product Description

 

Ultraviolet Transmissive and Visible Absorbing Filter
Ultraviolet(UV)transmissive and visible absorbing filters are optical components designed to selectively transmit or absorb specific wavelengths of UV and visible light.They are widely used in various fields such as spectroscopic analysis, imaging, and illumination.
I.Characteristics
Strong Wavelength Selectivity:These filters can precisely control the transmission or absorption of light within specific wavelength ranges.For example,they may allow only blue light in the 400-500nm range to pass through or absorb UV light in the 200-300nm range.
High Transmission/Absorption Efficiency: They exhibit high transmission rates (typically >80%) for target wavelengths and high absorption rates (typically >90%) for non-target wavelengths, thereby reducing stray light interference.
Good Stability:Constructed using optical glass or coating processes,these filters are resistant to high temperatures and corrosion,maintaining their optical properties over extended periods of use.
Flexible Sizing:They can be customized into various shapes and sizes,such as circular or square,to fit different devices like spectrometers,cameras,and lighting fixtures.
II.Main Functions
Wavelength Screening:In spectroscopic analysis,these filters remove irrelevant wavelengths,retaining only the target wavelengths(e.g.,254nm in the UV region or 550nm in the visible light region)to enhance detection accuracy.
Stray Light Elimination:They reduce interference from ambient light or scattered light within the device.For instance,in fluorescence detection,they filter out the excitation light,retaining only the fluorescence signal.
Light Intensity Regulation:By absorbing specific wavelengths of light,these filters control the intensity of light entering the system,preventing sensor overload or sample damage.
Application Adaptation:They can be customized for different scenarios,such as using UV-transmitting filters in UV sterilization lamps to enhance sterilization effects or optimizing color reproduction in camera lenses.
III.Application Areas
Spectroscopic Analysis(UV-Visible Spectrophotometry)
Biomedical Detection(Fluorescence Imaging,Nucleic Acid Detection)
Industrial Inspection(Material Defect Identification,Color Measurement)
Security Monitoring(Infrared Filters for Night Vision)
Illumination and Display(Stage Lighting,Display Backlight Adjustment)
