67-285 12.5 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=1.5mm 1150nm

The 67-285 Shortpass Filter, offered by Edmund Optics, is a circular filter designed for use in optical systems. This filter features a 12.5 mm diameter and a thickness of 1.5 mm, making it suitable for a wide range of applications. The filter is designed to block wavelengths above 1150 nm while allowing shorter wavelengths to pass through. This specific model is identified by the catalog number 67-285 and is available for purchase through the Edmund Optics website.

The filter's coating is a crucial aspect of its functionality. Both the front and back surfaces of the filter are coated with the EDM 67-285 coating, which is specifically designed to enhance the filter's performance. The coating ensures that the filter effectively blocks the specified wavelength range while minimizing unwanted reflections and scattering.

The filter's geometry is another important factor to consider. With a diameter of 12.5 mm, it is suitable for use in systems with similar aperture sizes. The thickness of 1.5 mm is also notable, as it can affect the filter's optical performance and its compatibility with other optical elements in the system.

This filter is classified as a Shortpass Filter, which is a type of optical filter that allows short-wavelength light to pass through while blocking longer wavelengths. This particular model is made from UVFS Mal-1965, a material known for its optical properties and durability.
