67-295 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1175nm

The 67-295 is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the renowned optical components vendor, Edmund Optics. This particular model boasts a 12.5 mm diameter and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.

The filter is designed to cut on at 1175 nm, meaning it starts to transmit light at this wavelength, while it cuts off at 0 nm, blocking all wavelengths shorter than this. This specific cut-on wavelength makes it ideal for applications that require the transmission of near-infrared light.

The 67-295 features a circular shape, a common form factor for optical components due to its ease of integration into various systems. It is made from UVFS Mal-1965, a material known for its optical properties and durability.

The filter is coated on both the front and back sides with the EDM 67-295 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission efficiency. The coating also provides protection to the filter against environmental factors, ensuring its longevity and reliability in operation.

The filter's thin lens shape allows for easy integration into optical systems, minimizing the need for additional lens elements and reducing the overall complexity of the system. This makes the 67-295 an attractive choice for users seeking a high-performance, easy-to-use longpass filter.
