The 66-106 is a 50 mm diameter color glass filter from the reputable vendor, Edmund Optics. This filter, identified by the catalog number 66-106, is a Longpass filter with a cut-on wavelength of 830nm, making it ideal for applications that require the transmission of infrared light.
The filter is made from SCHOTT RG830, a high-quality optical glass known for its excellent transmission properties in the infrared region. The filter has a thickness of 3mm, providing durability and stability. The base shape of the filter is circular, making it compatible with various optical systems.
The 66-106 filter features a thin lens shape, which is beneficial for applications that require minimal optical path deviation. The coating on both the front and back of the filter is EDM 54-663, which enhances the filter's performance by reducing surface reflections and increasing transmission.
The physical data of the filter indicates that it cuts off light below 830nm, ensuring optimal performance in longpass applications. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
