12-765 20 mm Dia. Black Optical Cast Infrared (IR) Longpass Color Filter
The 12-765 is a 20 mm diameter Optical Cast Plastic IR Longpass Filter, available from Edmund Optics. This filter is designed for use in the infrared spectrum, with a wavelength of 588 nm, making it ideal for applications that require the removal of visible light.
The filter is made from UVFS Mal-1965 material, a type of optical glass known for its excellent transmission properties in the infrared region. It features a circular shape and a thickness of 1.5 mm, providing a robust and compact design that is easy to integrate into various optical systems.
The 12-765 filter is coated with EDM IR-VIS on both the front and back surfaces. This coating enhances its performance in the infrared region while also providing protection against environmental factors. The coating also ensures high transmission and low reflection, which is crucial for maintaining image quality.
The filter has a thin lens shape, which is beneficial for applications that require a low profile or where space is limited. It is currently in stock and available for immediate purchase through the Edmund Optics website.
