521FCS2500 25 mm Dia. Colour Glass Bandpass Filter 520nm
The 521FCS2500 is a 25 mm diameter Color Glass Bandpass Filter, specifically designed to pass light in the 520nm wavelength range. Sourced from Knight Optical, a reputable vendor in the optical industry, this filter is a crucial component for various optical applications.
This filter is identified by its catalog number, 521FCS2500, and is available for purchase from Knight Optical's website, where it is currently in stock. The filter's primary function is to allow light to pass through a specific wavelength range while blocking other wavelengths, making it ideal for applications requiring wavelength selection and isolation.
The 521FCS2500 features a Base Shape of Circular, with a diameter of 25mm and a thickness of 3mm. It is made from UVFS Mal-1965, a material known for its optical properties and durability. The filter's coating, KNI 521FCS, is applied to both the front and back surfaces, enhancing its performance and longevity.
The filter's physical data includes a cut-on wavelength of 465nm and a cut-off wavelength of 565nm. This means that it begins to transmit light at 465nm and stops transmitting at 565nm. This wavelength range is crucial for applications requiring precise wavelength control.
