62-980 12.5 mm Dia. High Performance OD 4.0 Longpass Filter; t=2 mm 700nm
The 62-980 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm. This filter, offered by Edmund Optics, is designed to transmit light with wavelengths above 700 nm, making it ideal for applications that require the removal of shorter wavelengths.
The filter features a high optical density (OD) of 4.0, which is a measure of the amount of light it blocks. This high OD ensures effective suppression of unwanted light, enhancing the overall performance of your optical system. The filter's longpass characteristic is achieved through a precise cut-on wavelength of 700 nm, which is the point at which it begins to transmit light.
The 62-980 filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It is coated on both the front and back surfaces with EDM 62-980, a coating that contributes to its longpass performance and overall durability.
This filter is designed in a thin lens shape, which is a form factor that can be beneficial in many optical systems. The filter's geometry, combined with its high-performance characteristics, makes it a versatile choice for a wide range of applications.
According to the vendor's information, the filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
