69-869 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 650nm

The 69-869 is a Dichroic Longpass Filter, boasting a 12.5 mm diameter and a thickness of 1.05mm, sourced from the reputable optical vendor, Edmund Optics. This filter is designed to transmit light with wavelengths longer than 650nm, making it ideal for applications that require the separation of infrared light from visible light.

The filter's Dichroic properties are facilitated by a specialized coating on both the front and back surfaces, identified as 'edm 69-869'. This coating ensures high transmission of longer wavelengths while effectively blocking shorter wavelengths. The 'cut on' wavelength is 650nm, indicating the point at which the filter begins to significantly attenuate light. The 'cut off' wavelength is 0, suggesting that this filter allows all wavelengths longer than 650nm to pass through.

The 69-869 filter is designed in a Thin Lens shape, which is advantageous for applications where space is a constraint. The circular geometry of the filter, with a diameter of 12.5mm, adds to its versatility, making it suitable for a wide range of optical systems.
