670DF20 12.7 mm Dia. Surface Coating; Bandpass Filter Surface Coating
The 670DF20 is a Bandpass Filter, sourced from the reputable vendor, Omega Optical. This filter is characterized by its circular shape and a diameter of 12.7 mm, making it suitable for a wide range of optical applications. The filter has a thickness of 1.5 mm, providing a balance between durability and flexibility.
The filter's primary function is to allow light transmission within a specific wavelength range while blocking light outside this range. The 670DF20 is designed to permit light transmission at a central wavelength (CWL) of 670 nm. It features a cut-on wavelength of 660 nm and a cut-off wavelength of 680 nm, ensuring a tight control over the spectral bandwidth.
The filter's surface coating is another notable feature. Both the front and back surfaces are coated with "ome 670df20", a proprietary coating developed by Omega Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The 670DF20 is available in a Thin Lens shape, offering versatility in its integration into various optical systems. The filter's catalog number is 3151, and it can be found on the Omega Optical website, where it is currently in stock.
