The 69-215 is a Dichroic Shortpass Filter, measuring 25.2 x 35.6 mm, with a thickness of 1.05mm, sourced from Edmund Optics. This filter is designed to reflect shorter wavelengths and transmit longer wavelengths, making it ideal for applications that require the separation of light based on wavelength.
The filter's primary wavelength is 588nm, and it is designed to cut on at 0nm and cut off at 550nm. This specific cut-off wavelength is crucial in various applications, such as fluorescence microscopy, where it helps to eliminate unwanted background noise and enhance the signal-to-noise ratio.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties and durability. The front and back of the filter are coated with EDM 69-179, a broadband antireflection coating that reduces surface reflections and improves transmission.
The filter's rectangular shape and thin lens design make it compatible with a wide range of optical systems. It is currently in stock and available for immediate shipping, as indicated by its valid weblink status. For more information or to place an order, users can visit the provided weblink.
