The 730FDS12 is a Dichroic Filter, specifically designed for shortpass applications with a cut-off wavelength of 730nm. 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 homogeneity and low auto-fluorescence.
The filter has a circular shape with a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for a wide range of optical applications. The coating on both the front and back surfaces is 'kni 730fds-0', which is specifically designed to ensure the filter's performance in shortpass applications.
The 730FDS12 is a Thin Lens, meaning it has a very small thickness relative to its diameter, which can help minimize optical aberrations. The filter is currently in stock and available for immediate purchase through the vendor's website.
