34-748 12.5 x 17.6 mm High Performance Fluorescence Dichroic Filter 850nm

The 34-748 High Performance Fluorescence Dichroic Filter, offered by Edmund Optics, is a specialized optical component designed for applications involving fluorescence. This filter is rectangular in shape, with dimensions of 12.5 x 17.6 mm, and has a thickness of 1.05 mm, making it suitable for various optical systems.

The filter is designed to operate at a central wavelength of 850nm, which is a common wavelength used in fluorescence applications. It features a unique coating on both the front and back surfaces, specifically 'edm 34-748', which is engineered to enhance its performance in dichroic filtering.

The 'cut on' wavelength is set at 850nm, indicating that the filter begins to transmit light at this wavelength. The 'cut off' wavelength is 0, meaning it allows all wavelengths below 850nm to pass through. This characteristic makes it ideal for separating fluorescence emission from the excitation light.

The filter is categorized under the number 'uvfs mal- 1965' in the vendor's material ID system. It is available for purchase through the Edmund Optics website, and the link provided indicates that it is currently in stock.
