The 65-621 is a 12.5 mm diameter mounted traditional coated bandpass interference filter, specifically designed with a central wavelength (CWL) of 420nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their official website. The filter's current status indicates that it is in stock, ensuring prompt delivery upon order placement.
This optical component is classified as a bandpass filter, a type that allows light within a specific range of wavelengths to pass through while blocking other wavelengths. In this case, the 65-621 filter is designed to permit the transmission of light within the 415nm to 425nm range, making it ideal for applications that require the selective filtering of light in this spectrum.
The filter is constructed from UVFS Mal-1965 material, a choice that enhances its performance and durability. It features a circular base shape, a common design that ensures easy integration into various optical systems. The filter's geometry includes a diameter of 12.5mm and a thickness of 7.5mm, dimensions that should be considered when planning for its installation.
The 65-621 filter is coated on both the front and back surfaces with EDM 65-621, a proprietary coating that enhances its optical properties. The filter's shape is defined as a thin lens, a designation that suggests its minimal thickness and lightweight nature, making it a suitable choice for applications that require compact and lightweight optical components.
