49-030 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 700nm
The 49-030 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 49-030. It is available for purchase directly from the Edmund Optics website, where it is currently listed as in stock.
The 49-030 features a coating on both the front and back surfaces, identified as 'edm 49-030'. This coating plays a crucial role in the filter's performance, ensuring the specified wavelength cut-on of 700 nm. The cut-off wavelength is 0 nm, indicating that the filter blocks all wavelengths shorter than 700 nm.
The filter's geometry and physical data suggest that it is designed for high-precision applications. The diameter and thickness values indicate that it is a thin lens, a type of lens with a short focal length relative to its diameter. This design allows for a wide field of view and minimal distortion, making it ideal for imaging applications.
