65-699 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 520nm

The 65-699 is a 25 mm diameter mounted bandpass interference filter, specifically designed for applications requiring a center wavelength of 520nm. This filter, offered by Edmund Optics, is a crucial component in various optical systems, providing excellent optical performance and reliable functionality.

The filter is characterized by its thin lens shape, with a thickness of 7.5 mm, making it suitable for use in compact optical setups. The bandpass filter type ensures that only a specific range of wavelengths, centered around 520nm, are transmitted, while effectively blocking other wavelengths. This feature is particularly useful in applications such as fluorescence microscopy, spectroscopy, and other scenarios where wavelength selectivity is essential.

The 65-699 filter's physical data includes a cut-on wavelength of 515nm and a cut-off wavelength of 525nm, providing a narrow bandwidth for precise wavelength selection. The coating on both the front and back surfaces of the filter is EDMD 65-639, which contributes to its high transmission and excellent blocking capabilities.

For convenience and ease of use, the filter is mounted, making it ready for immediate integration into optical systems. The catalog number 65-699 uniquely identifies this specific filter, and it is currently in stock, ensuring quick delivery for your optical project needs.
