The 67-289 Shortpass Filter is a circular filter with a 25 mm diameter and a thickness of 3 mm, sourced from the reputable vendor Edmund Optics. This filter is designed for use in optical systems where short wavelengths need to be transmitted while longer wavelengths are blocked.
The filter's primary function is to cut off wavelengths beyond 1175 nm, making it ideal for applications that require the transmission of visible light and the rejection of infrared light. The 'Shortpass' attribute indicates that this filter allows shorter wavelengths to pass through while blocking longer wavelengths.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It features a thin lens shape, which is beneficial in applications where space is a constraint.
The filter's coating is another crucial aspect. Both the front and back surfaces are coated with EDM 67-286, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
The filter's catalog number is 67-289, and it is currently in stock, as indicated by its weblink status. For more information, users can visit the provided weblink: https://www.edmundoptics.com/p/1175nm-25mm-diameter-od-2-shortpass-filter/21797/.
