34-729 25.2 x 35.6 mm High Performance Fluorescence Dichroic Filter 450nm

The 34-729 is a high-performance fluorescence dichroic filter, specifically designed for use in optical systems where precise wavelength separation is required. This filter, sourced from the renowned vendor Edmund Optics, is a rectangular dichroic filter with a size of 25.2 x 35.6 mm and a thickness of 1.05 mm, making it suitable for a wide range of applications.

The filter is designed to have a cut-on wavelength of 450nm, meaning it begins to transmit light at this wavelength while reflecting shorter wavelengths. The cut-off wavelength is 0, indicating that it continues to transmit all longer wavelengths. This characteristic makes it ideal for use in fluorescence microscopy, where it can be used to separate the excitation light from the emitted fluorescence.

The 34-729 filter is coated with EDM 34-728 on both the front and back surfaces, enhancing its performance and durability. This coating ensures high transmission and reflection efficiency, as well as providing excellent environmental stability.

The filter is available in a thin lens shape, which is beneficial for applications where space is limited or where a flat, thin optical element is required. The catalog number for this item is 34-729, and it can be found on the Edmund Optics website, where it is currently in stock.
