66-229 12.5 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=2 mm 900nm

The 66-229 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to transmit light with wavelengths above 900 nm, while effectively blocking shorter wavelengths, making it ideal for various applications requiring longpass filtration.

The filter is constructed from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a circular shape, a standard in optical systems due to its symmetry and ease of alignment. The filter's coating, EDM 66-229, is applied to both the front and back surfaces, enhancing its performance and durability.

The 66-229 filter is designed to be thin, adopting a Thin Lens shape, which minimizes its impact on the overall optical path, making it suitable for systems with tight space constraints. According to the vendor's information, this filter is currently in stock, ensuring quick delivery for your optical system needs.
