520DIB25 25 mm Dia. Standard Interference Bandpass Filter 520nm

The 520DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 520nm range while blocking light at other wavelengths. This filter, offered by Knight Optical, is a crucial component for applications requiring narrowband transmission and high out-of-band blocking.

The filter is made from UVFS Mal-1965, a high-quality material known for its excellent optical properties. It features a circular base shape, with a thickness of 6.1mm, providing durability and stability. The filter's geometry is designed in a Thin Lens shape, which is beneficial for applications where minimal distortion and a flat field of view are required.

The 520DIB25 has a cut-on wavelength of 515nm and a cut-off wavelength of 525nm, ensuring a tight transmission band around the central wavelength of 520nm. This precise wavelength control is crucial in many applications, including fluorescence microscopy, spectroscopy, and laser technology.

The filter's front and back surfaces are coated with KNI 520DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The 520DIB25 is currently in stock and available for immediate purchase through the Knight Optical website. With its high-quality materials, precise wavelength control, and robust design, this filter is an excellent choice for a wide range of optical applications.
