590DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 590nm
The 590DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 590nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 585nm, and the cut-off wavelength is 595nm, ensuring a tight bandpass around the central wavelength. The central wavelength (CWL) of the filter is also 590nm, aligning with its design purpose.
The filter is made from UVFS Mal-1965, a material known for its optical properties suitable for this type of application. The filter has a Thin Lens shape, which is often preferred for its minimal thickness and weight. The geometry of the filter includes a diameter of 12.5mm and a thickness of 6.1mm, making it compact and easy to integrate into optical systems.
The coating on both the front and back surfaces of the filter is KNI 590DIB. This coating is specifically designed to enhance the filter's performance, ensuring optimal transmission within the passband and high blocking outside of it.
