69-871 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 750nm
The 69-871 Dichroic Longpass Filter is a circular filter with a diameter of 12.5 mm and a thickness of 1.05 mm. This filter, sourced from Edmund Optics, is designed to transmit light with wavelengths longer than 750 nm, making it ideal for applications that require the separation of infrared light.
The filter features a dichroic coating on both the front and back surfaces, identified as 'edm 69-871'. This coating is designed to reflect or transmit light depending on the wavelength, enabling the filter to perform its longpass function. The cut-on wavelength for this filter is 750 nm, meaning it begins to transmit light at this wavelength and beyond.
The filter is designed in the shape of a thin lens, which can be beneficial in certain optical systems where a flat surface is not preferred. The material ID for this filter is 'uvfs mal- 1965', although further details about the material are not provided in the item data.
The filter's catalog number is 69-871, and it can be found on the Edmund Optics website, where it is currently in stock. The item data also indicates that the weblink provided is valid, offering users a reliable source for further information or to make a purchase.
