The 48-642 50.8 x 50.8 mm SCHOTT BG39 (VIS) Blue-Green Colored Glass Bandpass Filter is a high-quality optical component designed for use in the visible light spectrum, specifically centered around 507nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for immediate use, as indicated by its "in stock" status on the vendor's website.
This filter is a type of Color Glass filter, which is known for its ability to selectively transmit light within a specific wavelength range while blocking other wavelengths. The BG39 (VIS) filter is rectangular in shape, with a base material identified as "uvfs mal- 1965". It has a width and height of 50.8mm each, and a thickness of 3mm, making it a substantial and robust optical element.
The filter's physical data includes a central wavelength (CWL) of 507nm, which is the wavelength at which the filter is most transmissive. This CWL is crucial in determining the filter's suitability for specific applications.
The coating on both the front and back surfaces of the filter is "edm 48-637". This coating plays a significant role in the filter's performance, enhancing its ability to selectively transmit and block light. The filter's shape is described as a "Thin Lens", suggesting that it may have some light-focusing capabilities.
