85-910 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1300nm

The 85-910 is a 50 mm diameter Bandpass Filter, specifically designed for use in the 1300nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase directly from their website. The catalog number for this item is 85-910.

This filter is characterized by its circular shape and Hard Coated OD 4.0 surface. The OD, or Optical Density, refers to the logarithmic ratio of incident to transmitted radiant power through a filter. A higher OD indicates a greater degree of opacity, making this filter ideal for applications requiring high levels of attenuation.

The filter has a thickness of 3.5 mm and a cut-on wavelength of 1275nm, and a cut-off wavelength of 1325nm. The central wavelength (CWL) is 1300nm, which is the wavelength at which the filter has its maximum transmittance. This makes it suitable for use in systems where a narrow band of wavelengths needs to be isolated.

The filter's coating is another key feature. Both the front and back surfaces of the filter are coated with EDM 85-886, a coating that enhances the filter's performance and durability. The filter's shape is that of a Thin Lens, which is beneficial in applications where a flat surface is not feasible or desirable.
