34-725 25.2 x 35.6 mm High Performance Fluorescence Dichroic Filter 409nm

The 34-725 is a high-performance fluorescence dichroic filter, designed and manufactured by Edmund Optics. This filter, with its catalog number 34-725, is a crucial component in various optical systems, particularly those involving fluorescence applications.

The filter is rectangular in shape, with a width of 25.2 mm and a height of 35.6 mm, making it suitable for use in compact optical setups. It has a thickness of 1.05 mm, which contributes to its robustness and durability.

The 34-725 filter is designed to operate at a central wavelength of 409nm. This wavelength is commonly used in fluorescence applications, making this filter a valuable tool for researchers and engineers in this field.

The filter's physical data includes a cut-on wavelength of 409nm and a cut-off wavelength of 0nm. This means that the filter begins to transmit light at 409nm and continues to do so for all longer wavelengths.

The filter's coating is another critical aspect of its design. Both the front and back surfaces of the filter are coated with EDM 34-724, a specific coating developed by Edmund Optics. This coating enhances the filter's performance and durability.

The filter's shape is described as a Thin Lens, indicating its potential use in focusing or collimating light beams. This versatile filter is available for purchase through the Edmund Optics website, where it is listed as being in stock.
