The 47-288 is a 25 mm diameter Shortpass Filter with a thickness of 3mm, designed for use in optical systems where short wavelengths need to be transmitted while longer wavelengths are blocked. This filter, sourced from Edmund Optics, has a catalog number of 47-288 and is available for purchase directly from their website.
The filter's primary function is to cut off wavelengths beyond 550nm, making it ideal for applications that require the transmission of visible light up to a certain point in the spectrum. The front and back of the filter are coated with EDM 47-813, a traditional coating that enhances its performance and durability.
The 47-288 filter is designed in a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter's geometry, including its 25mm diameter and 3mm thickness, is optimized for compatibility with various optical systems.
