FF01-635/18-25 25 mm Dia. 635/18nm BrightLine Single-Band Bandpass Filter by Semrock

The FF01-635/18-25 is a Bandpass Filter, specifically designed for circular geometries with a diameter of 25 mm and a thickness of 2 mm. This filter is sourced from the reputable vendor, Semrock, and boasts a catalog number of FF01-635/18-25. The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths.

The FF01-635/18-25 is designed to pass light at a central wavelength (CWL) of 635 nm, with a cut-on wavelength of 626 nm and a cut-off wavelength of 644 nm. This precise wavelength selection is facilitated by the high-quality coating on both the front and back of the filter, which is identified as "sem ff01-63518".

The filter's physical data, including the cut-on and cut-off wavelengths, are critical in determining its performance in various applications. The filter's Base Shape, a Thin Lens, further enhances its performance by minimizing optical aberrations.

The filter's current status is "in stock", and it is available for purchase through the vendor's website, with the weblink provided in the item data. This filter is a valuable addition to any optical system requiring precise wavelength selection in the 635 nm range.
