66-045 12.5 mm Dia. Hoya R-66 Red Longpass Color Glass Filter 660nm

The 66-045 Hoya R-66 Red Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a specific wavelength of 660nm. This filter is sourced from Edmund Optics, a leading global manufacturer and supplier of optical components.

The filter is a circular shape with a diameter of 12.5mm and a thickness of 2.5mm, making it suitable for use in compact optical systems. It is made from UVFS Mal-1965, a material known for its optical properties and durability.

The R-66 filter features a longpass cut-on wavelength of 660nm, meaning it begins to transmit light at this wavelength and continues to transmit longer wavelengths. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than 660nm. This makes it ideal for applications that require the isolation of specific wavelengths or the reduction of unwanted shorter wavelengths.

The filter's front and back surfaces are coated with EDM 66-045, a coating that enhances its optical performance and durability. The filter's shape is thin lens, further optimizing its performance in optical systems.
