FF01-685/LP-25 25 mm Dia. 685nm Blocking Edge BrightLine Long-Pass Filter by Semrock

Semrock's FF01-685/LP-25 is a Longpass Filter with a circular shape, designed to block wavelengths of 685nm and below while transmitting longer wavelengths. This filter boasts a 25mm diameter and a thickness of 2mm, making it suitable for a wide range of optical applications.

The filter is made from UVFS Mal-1965 material, a popular choice for its excellent optical properties. It features a thin lens shape, which helps to minimize optical aberrations and ensures high-quality performance. The FF01-685/LP-25 is coated on both the front and back surfaces with the same coating, Sem FF01-685LP, which enhances its performance and durability.

This filter is designed to cut on at 685nm, meaning it begins to block wavelengths at this point, and has a cut off of 0, indicating that it transmits all wavelengths longer than 685nm. This makes it ideal for applications where the detection of longer wavelengths is required, such as in fluorescence microscopy, bio-imaging, or any other application involving the separation of light based on wavelength.

The FF01-685/LP-25 is currently in stock and available for purchase on the Semrock website. For more information, please refer to the provided weblink.
