89-657 12.5 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 1150nm

The 89-657 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 3 mm, sourced from the reputable vendor, Edmund Optics. This filter is specifically designed for use in optical systems that require a longpass cut-on wavelength of 1150nm.

The filter's primary function is to transmit light at wavelengths greater than 1150nm while blocking or attenuating light at wavelengths below this point. This makes it an ideal component for applications that demand the separation of infrared light from visible or ultraviolet light.

The 89-657 filter is constructed from UVFS Mal-1965 material, a choice that ensures durability and high optical performance. It features hard coating on both the front and back surfaces, further enhancing its robustness and resistance to wear and tear.

The filter's thin lens shape allows for easy integration into various optical systems, while its circular geometry provides versatility in terms of alignment and positioning. The catalog number for this item is 89-657, and it is currently in stock, as indicated by its valid weblink status.
