69-868 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 600nm

The 69-868 Dichroic Longpass Filter is a high-quality optical component manufactured by Edmund Optics. This filter is designed with a circular shape, featuring a 12.5 mm diameter and a thickness of 1.05mm, making it suitable for a wide range of optical applications.

The filter is made from UVFS MAL-1965 material, a common choice in the industry due to its excellent optical properties. The filter's primary function is to separate light based on wavelength, specifically allowing light with wavelengths longer than 600nm to pass through while blocking shorter wavelengths. This is achieved through the application of a specialized coating, denoted as 'edm 69-868', on both the front and back surfaces of the filter.

The cut-on wavelength for this filter is 600nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0nm, meaning it blocks all wavelengths shorter than 600nm. This makes the 69-868 filter an ideal choice for applications where longpass filtering is required.

The filter is designed to be used as a Thin Lens, further expanding its potential applications. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
