49-031 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 750nm
The 49-031 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model has a diameter of 12.5 mm and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.
The filter is manufactured by Edmund Optics, a leading supplier of optical components, and is identified by the catalog number 49-031. It is available for purchase directly from the vendor's website, where it is currently listed as in stock.
The 49-031 features a coating on both the front and back surfaces, identified as 'edm 49-031'. This coating is designed to enhance the filter's performance and durability. The filter's geometry is defined by a Thin Lens shape, which is a lens with a very short focal length compared to its diameter.
The physical data of the 49-031 includes a cut-on wavelength of 750 nm, which is the wavelength at which the filter starts to transmit light. The cut-off wavelength, on the other hand, is 0 nm, indicating that the filter blocks all wavelengths shorter than its cut-on value.
