69-880 12.5 x 17.6 mm Dichroic Longpass Filter; t=1.05mm 650nm

The 69-880 is a Dichroic Longpass Filter, measuring 12.5 x 17.6 mm, with a thickness of 1.05mm, sourced from Edmund Optics. This filter is designed to transmit light at wavelengths longer than 650nm, making it ideal for applications that require the separation of infrared and visible light.

The filter features a dichroic coating on both the front and back surfaces, identified as EDM 69-869. This coating is specifically designed to reflect or transmit light depending on the wavelength, enhancing its longpass filtering capabilities. The cut-on wavelength is set at 650nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it allows all wavelengths shorter than 650nm to pass through.

The filter is rectangular in shape and is categorized as a Thin Lens. It is made from UVFS MAL-1965 material, a common choice for optical filters due to its excellent transparency and durability. The filter's dimensions make it suitable for use in a wide range of optical systems, including microscopes, spectrometers, and imaging devices.

According to the vendor's website, the 69-880 is currently in stock, ensuring quick delivery for those who need it. The filter's specifications, including its size, thickness, and coating, make it a versatile and reliable choice for various optical applications.
