69-189 12.5 x 17.6 mm Dichroic Shortpass Filter; t=1.05mm 450nm

The 69-189 Dichroic Shortpass Filter is a rectangular optical component, measuring 12.5 x 17.6 mm, with a thickness of 1.05mm. This filter is sourced from Edmund Optics, a renowned vendor in the optical industry. It is designed to selectively transmit light below a specified wavelength while reflecting light above that wavelength, making it ideal for applications that require the separation of different spectral regions.

The filter's primary function is to cut off light at 450nm, allowing only shorter wavelengths to pass through. This is particularly useful in applications such as fluorescence microscopy, where it is crucial to isolate specific wavelength ranges. The filter's coating, denoted as 'edm 69-177' on both the front and back surfaces, ensures optimal performance in this regard.

The 69-189 filter is categorized as a Dichroic Filter, a type of filter that reflects one wavelength and transmits another. It is made from a material identified as 'uvfs mal- 1965', further enhancing its performance in specific wavelength ranges. The filter's geometry, with a width of 12.5mm and a height of 17.6mm, is designed to fit into standard optical systems, making it a versatile choice for various applications.

According to the vendor's information, this filter is currently in stock and available for immediate purchase. For more detailed information, including technical specifications and purchasing options, please refer to the vendor's website through the provided link.
