530DIB25 25 mm Dia. Standard Interference Bandpass Filter 530nm
The 530DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 530nm. 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 transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 525nm, and the cut-off wavelength is 535nm, ensuring a tight bandpass around the central wavelength. The Central Wavelength (CWL) of this filter is 530nm, providing a high transmission rate within this range.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a circular base shape, a common design for ease of integration into various optical systems. The geometry of the filter includes a diameter of 25mm and a thickness of 6.1mm, making it suitable for applications requiring a thin lens design.
The coating on both the front and back surfaces of the filter is KNI 530DIB. This coating is specifically designed for this filter, enhancing its performance and durability. The coating ensures high transmission rates within the passband and low reflection rates, making it an ideal choice for applications requiring high-quality light transmission.
