67-081 25.2 x 35.6 mm Fluorescence Dichroic Filter 520nm

The 67-081 Fluorescence Dichroic Filter, offered by Edmund Optics, is a high-quality optical component designed for use in fluorescence applications. This filter is specifically designed to transmit light at a wavelength of 520nm, making it ideal for use in systems where this wavelength is of interest.

The filter is rectangular in shape, with dimensions of 25.2mm in width and 35.6mm in height. This size makes it suitable for use in a wide range of optical systems, from compact setups to larger, more complex designs. The filter has a thickness of 1.05mm, which is thin enough to minimize unwanted optical effects while still providing robust mechanical support.

The 67-081 filter is coated with a specialized coating on both the front and back surfaces. This coating, identified as EDM 67-057, is designed to enhance the filter's performance by reducing unwanted reflections and increasing transmission at the desired wavelength. The coating also helps to protect the filter from environmental damage, ensuring long-lasting performance.

The filter's physical data includes a cut-on wavelength of 520nm and a cut-off wavelength of 0nm. This means that the filter begins to transmit light at 520nm and continues to transmit all wavelengths beyond this point. This characteristic makes the filter ideal for use in fluorescence applications, where it can be used to isolate the fluorescence signal from the excitation light.
