590DIB25 25 mm Dia. Standard Interference Bandpass Filter 590nm
The 590DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 590nm range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the cut-on wavelength is 585nm, and the cut-off wavelength is 595nm, making it highly effective in isolating the 590nm light. The Central Wavelength (CWL) of the filter is also 590nm, ensuring optimal performance.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thin lens design, making it suitable for a wide range of applications. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a good balance between compactness and durability.
The filter's coating is KNI 590DIB, which is applied on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable operation even under demanding conditions.
