69-866 12.5 mm Dia. Dichroic Longpass Filter; t=1.05mm 500nm

The 69-866 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 500 nm, making it ideal for applications that require the separation of visible and infrared light.

The filter's coating, denoted as 'edm 69-866' on both the front and back surfaces, is specifically designed to achieve this longpass characteristic. The cut-on wavelength is 500 nm, meaning that it begins to transmit light at this point in the spectrum. The cut-off wavelength, on the other hand, is 0 nm, indicating that it will transmit all wavelengths longer than the cut-on point.

This filter is categorized as a Dichroic Filter, which is a type of filter that reflects or transmits light depending on its wavelength. The material ID for this filter is 'uvfs mal- 1965', although the specific properties and characteristics of this material are not provided in the item data.

The filter is designed to be used as a Thin Lens, suggesting that it may have some degree of focusing or diverging capability. However, the specific optical power or other lens parameters are not provided in the item data.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by the 'weblink status' field in the item data.
