15-452 12.7 mm Dia. Dielectric Coated Colored Glass Replacement Longpass Filter 850nm

The 15-452 is a specialized optical filter developed by Edmund Optics, designed primarily for use in applications requiring longpass filtering at the 850nm wavelength. This filter boasts a 12.7 mm diameter and a thickness of 1.1 mm, making it a versatile and compact solution for various optical systems.

The filter is constructed from UVFS Mal-1965, a unique material that provides excellent optical properties. The base shape of the filter is circular, ensuring easy integration into most optical setups. The filter's coating, both on the front and back, is Edmund Optics' proprietary EDM 15-452, which enhances the filter's performance and durability.

The 15-452 filter features a cut-on wavelength of 850nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths below this point. This makes it an ideal choice for applications where longpass filtering is required.

The filter's geometry is that of a thin lens, which helps minimize optical aberrations and distortions. This, coupled with its compact size, makes the 15-452 an excellent choice for applications where space is at a premium.

The filter is currently in stock and can be purchased directly from the Edmund Optics website. Detailed product information, including pricing and availability, can be found at the provided weblink.
