69-185 12.5 mm Dia. Dichroic Shortpass Filter; t=1.05mm 850nm

The 69-185 is a Dichroic Filter with a 12.5 mm diameter and a thickness of 1.05mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed with a specific wavelength of 588nm, making it suitable for a wide range of applications that require precise wavelength control.

The filter is categorized as a Shortpass Filter, indicating that it allows wavelengths shorter than the specified cutoff to pass through while blocking longer wavelengths. In this case, the cutoff is set at 850nm, ensuring that only wavelengths shorter than this are transmitted. This feature is particularly useful in applications such as fluorescence microscopy, where it's crucial to isolate and observe specific wavelengths.

The 69-185 is coated with a proprietary dichroic coating on both the front and back surfaces, identified as 'edm 69-185'. This coating enhances the filter's performance, ensuring efficient wavelength separation and minimal signal loss. The filter's thin lens shape further contributes to its performance, providing a compact and lightweight solution for optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its 'Valid - in stock' weblink status. For more detailed information and specifications, users are encouraged to visit the provided weblink.
