The 14-435 is a 50 x 50 mm SCHOTT BG62 Blue-Green Harsh Environment Colored Glass NIR Cut-Off Filter, designed to block near-infrared (NIR) light at a cut-off wavelength of 500nm. This filter is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The filter is made of color glass, a type of optical filter that uses colored glass to alter the properties of light. This particular filter is rectangular in shape, making it suitable for a wide range of optical applications. It has a thickness of 1mm, providing durability while maintaining a low profile.
The 14-435 features a coating on both the front and back surfaces, identified as 'edm 14-435'. This coating is designed to enhance the filter's performance and durability, making it suitable for harsh environment use.
The physical data of this filter includes a center wavelength (CWL) of 500nm, indicating the wavelength at which the filter begins to block light. This makes it ideal for applications where NIR light needs to be selectively filtered out.
In terms of geometry, the filter has a width of 50mm and a height of 50mm, providing a substantial surface area for light interaction. The filter's shape is classified as a 'Thin Lens', suggesting that it may have some light focusing capabilities, although this is not its primary function.
