62-974 12.5 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=2 mm 400nm

The 62-974 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm. This filter, sourced from Edmund Optics, is designed to transmit light with wavelengths above 400 nm, making it ideal for applications that require the blocking of ultraviolet light. The filter's longpass characteristic is achieved through a precise cut-on wavelength of 400 nm, ensuring efficient blocking of shorter wavelengths.

The 62-974 filter is constructed with a high-quality UVFS material, identified as Mal-1965, which is known for its excellent optical properties. The filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear, a crucial factor for applications involving frequent handling or harsh environments.

This filter is designed in a thin lens shape, optimized for use in optical systems where space is at a premium. The catalog number for this item is 62-974, and it is currently in stock, according to the vendor's website. For more information, users are encouraged to visit the product link provided.
