The 14-481 is a 50 x 50 mm SCHOTT GG435 Yellow Colored Glass Longpass Filter, designed to transmit light with wavelengths longer than 435nm. This filter is sourced from Edmund Optics and is available for purchase on their website, with a current status of being in stock.
The filter is made of color glass, a type of optical filter that uses colored glass to block specific wavelengths of light. This particular filter is rectangular in shape and has a thickness of 1mm. The GG435 material ID indicates that it is a Schott glass type, known for its high transmission and low autofluorescence.
The physical data of the filter indicates that it is cut on at 435nm, meaning it begins to transmit light at this wavelength. The cut off is 0, indicating that it continues to transmit all longer wavelengths. This makes it a longpass filter, ideal for applications where shorter wavelengths need to be blocked.
The filter features the same coating on both the front and back, denoted as 'edm 14-481'. This coating likely serves to enhance the filter's performance, such as by increasing its durability or improving its transmission characteristics.
The filter's shape is described as a 'Thin Lens', suggesting that it may have some degree of lens-like behavior, such as focusing or diverging light. However, without further information, it is difficult to specify the exact nature of this lens-like behavior.
