520FCS2500-MO 28 mm Dia. Mounted Colour Glass Bandpass Filter 415nm

The 520FCS2500-MO is a mounted color glass bandpass filter, designed and manufactured by Knight Optical. This filter is specifically engineered to transmit light within the 415nm wavelength range while blocking other wavelengths, making it ideal for applications that require narrow-band light transmission.

The filter boasts a 28 mm diameter and a thickness of 3 mm, providing a robust and compact design that ensures ease of integration into various optical systems. The base shape of the filter is circular, which is a common and versatile shape in optical applications.

The material used for this filter is UVFS MAL-1965, a high-quality optical material known for its excellent transmission properties and durability. This material is specifically chosen for its ability to transmit light within the specified wavelength range while blocking unwanted light.

The filter's coating is another crucial aspect of its design. Both the front and back surfaces of the filter are coated with KNI 420FCS, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The physical data of the filter includes a cut-on wavelength of 415nm and a cut-off wavelength of 575nm. The cut-on wavelength is the shortest wavelength that the filter begins to transmit, while the cut-off wavelength is the longest wavelength that the filter continues to transmit. The central wavelength (CWL) of the filter is also 415nm, which is the wavelength at which the filter's transmission is maximum.

In terms of shape, the filter is designed as a thin lens. This shape not only provides a sleek and compact design but also minimizes optical aberrations, ensuring optimal light transmission and image quality.

The 520FCS2500-MO is currently in stock and available for purchase on the Knight Optical website. With its high-quality materials, advanced coating, and precise design, this filter is an excellent choice for various optical applications that require narrow-band light transmission.
