430DIB50 50 mm Dia. Standard Interference Bandpass Filter 430nm

The 430DIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 430nm wavelength range while blocking light at other wavelengths. 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 spectrums. It has a base shape of a circle, a standard geometry for optical components due to its uniformity and ease of integration into various systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unnecessary weight.

The 430DIB50 has a cut-on wavelength of 425nm and a cut-off wavelength of 435nm, meaning it begins transmitting light at 425nm and stops transmitting at 435nm. The central wavelength (CWL) of this filter is 430nm, indicating the peak of its transmission curve. This makes it ideal for applications that require narrow-band light in the blue region of the visible spectrum.

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 optimizing its light transmission capabilities.
