FF01-494/34-25 25 mm Dia. 494/34nm BrightLine Single-Band Bandpass Filter by Semrock
The FF01-494/34-25 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 is in stock, ensuring prompt delivery upon order placement.
The filter is made from UVFS MAL-1965 material, a choice that enhances its performance and durability. It has a wavelength of 494 nm, a crucial specification that determines its light-filtering capabilities. The geometry of the filter includes a thickness of 2 mm, providing a balance between robustness and compactness.
The FF01-494/34-25 features a cut-on wavelength of 477 nm and a cut-off wavelength of 511 nm. These values are critical in determining the range of wavelengths that the filter allows to pass through. The central wavelength (CWL) is 494 nm, indicating the wavelength at which the filter's transmittance is maximum.
The filter's coating is another essential feature. Both the front and back of the filter are coated with SEM FF01-49434, a coating that likely enhances the filter's performance and longevity. The filter's shape is described as a Thin Lens, suggesting that it may have lens-like properties, such as focusing light.
