520FDS25 25 mm Dia. Shortpass Dichroic Filter 520nm

The 520FDS25 is a 25 mm diameter Shortpass Dichroic Filter, specifically designed to transmit light below the 520nm wavelength while reflecting light above this wavelength. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. It has a diameter of 25mm and a thickness of 1.1mm, making it suitable for various optical applications.

The 520FDS25 features a cut-on wavelength of 746nm and a cut-off wavelength of 520nm. This means it begins to transmit light at 746nm and stops transmitting at 520nm, effectively reflecting all light above this wavelength. This characteristic makes it ideal for applications where short wavelength light needs to be isolated.

The filter is coated with KNI 520FDS-0 on both the front and back surfaces. This coating enhances its performance and durability, ensuring reliable and consistent operation. The filter's shape is that of a thin lens, further expanding its potential applications in optical systems.
