445FCS2500 25 mm Dia. Colour Glass Bandpass Filter 445nm

The 445FCS2500 is a 25 mm diameter Color Glass Bandpass Filter, specifically designed to transmit light at a central wavelength of 445nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from UVFS Mal-1965, a material that is specifically chosen for its optical properties. It has a base shape of a circle, with a diameter of 25mm and a thickness of 3mm, making it suitable for a wide range of optical applications.

The 445FCS2500 features a cut-on wavelength of 365nm and a cut-off wavelength of 480nm, with a center wavelength (CWL) of 445nm. This means it allows light within this specific range to pass through while blocking other wavelengths, making it ideal for applications that require narrowband filtering.

The filter is coated with KNI 445FCS on both the front and back surfaces, which enhances its performance and durability. Its shape is that of a thin lens, further expanding its potential uses in various optical systems.

According to the vendor, this item is currently in stock and the provided web link leads to its product page on Knight Optical's website. This filter is a reliable and efficient solution for applications that require narrowband filtering at the 445nm wavelength.
