430FIB50 50 mm Dia. Standard Interference Bandpass Filter 430nm
The 430FIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to pass light in the 430nm wavelength range while blocking light outside this range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties in the ultraviolet and visible light spectrum. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortions.
The 430FIB50 features a cut-on wavelength of 425nm and a cut-off wavelength of 435nm, ensuring a narrow and precise bandpass. The central wavelength (CWL) is 430nm, indicating the peak transmission wavelength. This makes the filter ideal for applications that require precise wavelength selection, such as fluorescence microscopy, spectroscopy, and laser systems.
Both the front and back surfaces of the filter are coated with KNI 430DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The filter's shape is that of a thin lens, further minimizing optical distortions and ensuring easy integration into existing optical systems.
