FF01-520/5-25 25 mm Dia. 520/5nm BrightLine Single-Band Bandpass Filter by Semrock

Semrock's FF01-520/5-25 is a Bandpass Filter, specifically designed for applications requiring high transmission and steep roll-off in the visible spectrum. This filter features a circular shape with a diameter of 25 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems.

The filter is centered at 520 nm, with a 5 nm bandwidth, providing a high degree of wavelength specificity. The cut-on wavelength is 517.5 nm, and the cut-off wavelength is 522.5 nm, ensuring minimal transmission outside of the desired bandwidth. This precise wavelength control is crucial in many applications, such as fluorescence microscopy, where specific wavelengths need to be isolated.

The FF01-520/5-25 is made from UVFS material, identified as MAL-1965 in Semrock's catalog. This material is known for its excellent optical properties and durability, ensuring reliable performance over time. The filter is coated on both sides with Semrock's FF01-5205 coating, which further enhances its performance by reducing reflection and increasing transmission.

The filter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for purchase on Semrock's website, as indicated by its valid weblink status. For more information or to make a purchase, users can follow the provided weblink.
