420DIB25 25 mm Dia. Standard Interference Bandpass Filter 420nm

The 420DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 420nm 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 spectrum. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a robust and stable platform for optical applications.

The 420DIB25 features a cut-on wavelength of 415nm and a cut-off wavelength of 425nm, meaning it begins transmitting light at 415nm and stops transmitting at 425nm. The central wavelength (CWL) of this filter is 420nm, indicating the peak of its transmission curve. This makes it ideal for applications that require narrowband light in the blue region of the spectrum.

Both the front and back surfaces of the filter are coated with KNI 420DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation in various environments.

The filter's shape is that of a thin lens, allowing it to be easily integrated into existing optical systems. It is currently in stock and available for immediate purchase, as indicated by its weblink status. For more information, users can visit the provided weblink.
