480FDS12 12.5 mm Dia. Shortpass Dichroic Filter 480nm

The 480FDS12 is a high-quality dichroic filter, 12.5 mm in diameter, designed for shortpass applications with a cut-off wavelength of 480nm. This filter is sourced from Knight Optical, a reputable vendor known for their extensive catalog of optical elements.

The filter is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. It has a thickness of 1.1mm, providing durability and resistance to external stressors. The filter's geometry, including its diameter and thickness, is designed to ensure optimal performance in its specified application.

The 480FDS12 features a dichroic coating on both the front and back surfaces, specifically 'kni 480fds-0'. This coating is designed to reflect or transmit light depending on the wavelength, making it ideal for shortpass applications where light below 480nm is to be filtered out.

The filter's physical data indicates a cut-on wavelength of 866nm. This, combined with the cut-off wavelength, provides a clear picture of the filter's transmission properties.

The filter is shaped as a thin lens, which is often used in optical systems to bend light and focus it to a specific point. This shape, along with the filter's other specifications, makes the 480FDS12 a versatile and reliable option for shortpass dichroic filter applications.
