450FDS12 12.5 mm Dia. Shortpass Dichroic Filter 450nm

The 450FDS12 is a high-quality dichroic filter, 12.5 mm in diameter, designed for shortpass applications with a cutoff wavelength of 450nm. 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 widely used optical glass due to its excellent optical properties and high homogeneity. It has a thickness of 1.1mm, providing sufficient structural integrity while maintaining minimal optical distortion. The filter's geometry, including its diameter and thickness, is designed to ensure easy integration into various optical systems.

The 450FDS12 features a dichroic coating on both the front and back surfaces, specifically KNI 450FDS-0. This coating is designed to reflect or transmit light depending on its wavelength, making it ideal for shortpass applications where light below 450nm is to be filtered out. The cut-on wavelength is 846nm, indicating that the filter starts to transmit light at this wavelength.

The filter's shape is defined as a thin lens, suggesting that it may have some lens-like properties, although this is not explicitly stated in the provided data. Regardless, this filter is a reliable and efficient solution for applications requiring shortpass filtration, particularly those involving blue light.
