49-029 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 650nm
The 49-029 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 49-029. It is available for purchase directly from the vendor's website, where it is currently listed as in stock.
The 49-029 features a cut-on wavelength of 650 nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength, which is the point at which the filter stops transmitting light, is 0 nm. This specific characteristic makes the 49-029 particularly useful in applications where longer wavelengths need to be isolated or emphasized.
The filter is coated on both the front and back surfaces with the EDM 49-029 coating. This coating enhances the filter's performance and durability, ensuring reliable operation in various conditions.
The 49-029 is designed in the shape of a Thin Lens, a type of lens with a short focal length and a small diameter. This design allows for efficient light transmission and minimal distortion, making the filter ideal for precision optical applications.
