FF01-513/17-25 25 mm Dia. 513/17nm BrightLine Single-Band Bandpass Filter by Semrock

The FF01-513/17-25 is a Bandpass Filter, specifically designed with a circular shape and a diameter of 25 mm. This filter is sourced from the reputable vendor, Semrock, and is readily available for purchase through their online store. The item data indicates that it has a thickness of 2 mm, making it a compact and convenient option for various optical applications.

The filter's primary function is to allow light transmission within a specific wavelength range, while blocking out unwanted wavelengths. The FF01-513/17-25 is designed to pass light at a central wavelength (CWL) of 513 nm, with a cut-on wavelength of 504.5 nm and a cut-off wavelength of 521.5 nm. This precise wavelength selection makes it an ideal component for applications that require narrow-band light transmission.

The filter's coating, both on the front and back, is identified as "sem ff01-51317". This coating plays a crucial role in ensuring the filter's performance, providing the specified wavelength selectivity and transmission characteristics. The filter's shape is described as a Thin Lens, suggesting that it may have additional optical properties beyond simple wavelength filtering.
