450FDS25 25 mm Dia. Shortpass Dichroic Filter 450nm

The 450FDS25 is a high-quality dichroic filter, sourced from Knight Optical, designed for shortpass applications with a 450nm cutoff wavelength. This filter is circular in shape, featuring a 25mm diameter and a thickness of 1.1mm, making it suitable for a wide range of optical systems.

The filter is constructed using N-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. This ensures the filter can withstand harsh environmental conditions and maintain its performance over time.

The 450FDS25 features a dichroic coating on both the front and back surfaces, specifically designed to reflect or transmit light depending on its wavelength. The front coating, 'kni 450fds-0', allows light below 450nm to pass through while reflecting light above this wavelength. Conversely, the back coating, also 'kni 450fds-0', reflects light below 450nm and transmits light above this wavelength.

This filter is designed for thin lens applications, ensuring minimal interference with the overall optical path. The 450FDS25 is currently in stock and available for immediate shipping, as indicated by its 'Valid - in stock' weblink status.
