530nm Band Pass Optical Filter For Photometry

A 530nm band pass optical filter is a type of optical filter that is designed to selectively transmit light within a specific wavelength range centered around 530 nanometers (nm). This wavelength range is often called the green spectral region of the electromagnetic spectrum.

 

Our filter is designed and manufactured to precise specifications to ensure consistent and reliable performance. It is constructed with a thin layer of material designed to absorb or reflect unwanted wavelengths of light that can interfere with the observation while effectively transmitting the desired 530nm wavelength (transmission rate>90%, OD6), an ideal component for scientific and industrial applications.

How does 530nm band pass optical filter apply in photometry?

In photometry, 530nm bandpass filters selectively measure light intensity within the 530nm wavelength range, vital in various applications, such as astronomy, environmental monitoring, and industrial inspection.

 

One common use of the filter in photometry is measuring chlorophyll concentration in water. Chlorophyll absorbs light strongly in the 430nm and 670nm wavelengths but reflects light in the 530nm wavelength range. By measuring the intensity of light transmitted through a water sample using the filter, scientists can determine the amount of chlorophyll in the water.

 

In astronomy, they are used to measure the brightness of stars in the green spectral region, which is essential for studying the properties of stars and galaxies and monitoring changes in the brightness of celestial objects over time.

 

In industrial inspection applications, 530nm bandpass filters can detect defects or variations in materials visible only in the green spectral region, which can help inspect electronic components, textiles, and other materials.
