570FIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 570nm
The 570FIR12 is a high-quality bandpass filter, designed and manufactured by Knight Optical. This particular model is a circular filter, with a diameter of 12.5 mm and a thickness of 6.1 mm, making it suitable for a wide range of optical applications.
The filter is made from UVFS MAL-1965, a material known for its excellent optical properties. It is designed to transmit light within a specific wavelength range, while blocking light outside of this range. The cut-on wavelength is 550nm, and the cut-off wavelength is 590nm, with the central wavelength at 570nm. This makes it ideal for applications where light in the orange part of the spectrum is required.
The 570FIR12 features a KNI 570DIR coating on both the front and back surfaces. This coating enhances the filter's performance, ensuring high transmission and excellent blocking characteristics. The filter's shape is that of a thin lens, which contributes to its versatility and ease of use in various optical systems.
According to the vendor's information, this filter is in stock and available for immediate dispatch. Further details, including technical specifications and purchasing information, can be found on the Knight Optical website.
