66-047 12.5 mm Dia. Hoya IR-76 Black Longpass Color Glass Filter 760nm
The 66-047 is a 12.5 mm diameter circular filter from Hoya, available through Edmund Optics. This filter is a Longpass Color Glass type, designed to transmit light with wavelengths longer than 760nm while blocking shorter wavelengths.
The filter is made of UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It has a physical cut-on wavelength of 760nm and a cut-off wavelength of 0nm, ensuring a high level of blocking for unwanted wavelengths.
The filter has a thickness of 2.5mm, which is typical for this type of optical component. It features a Thin Lens shape, which is beneficial for applications where minimal optical path deviation is required.
The 66-047 filter is coated on both the front and back surfaces with EDM 66-047, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality construction, advanced coating, and precise specifications, the 66-047 filter is an excellent choice for a wide range of optical applications.
