430DIB25 25 mm Dia. Standard Interference Bandpass Filter 430nm

The 430DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 430nm wavelength range while blocking light at other wavelengths. This filter, offered by Knight Optical, is a crucial component for applications requiring precise wavelength selection and control.

The filter is made from UVFS MAL-1965, a high-quality material known for its excellent optical properties. It features a circular base shape, with a diameter of 25 mm and a thickness of 6.1 mm, making it suitable for a wide range of optical systems.

The 430DIB25 has a Cut-On wavelength of 425nm and a Cut-Off wavelength of 435nm, ensuring a narrow bandpass around the Center Wavelength (CWL) of 430nm. This specificity makes it ideal for applications requiring tight wavelength control, such as fluorescence microscopy, spectroscopy, and laser technology.

The filter is coated with KNI 430DIB on both the front and back surfaces, enhancing its performance and durability. Its Thin Lens shape further adds to its versatility, allowing it to be easily integrated into various optical setups.
