49-038 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 1100nm

The 49-038 is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the renowned 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 1100 nm, meaning it begins to transmit light at this wavelength, while blocking all wavelengths below this point. This characteristic makes it ideal for applications where the detection of longer wavelengths is crucial, such as infrared (IR) spectroscopy or astronomy.

The 49-038 model features a circular shape and is coated on both the front and back with the EDM 49-038 coating. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation. The filter's thin lens shape further adds to its versatility, making it compatible with various optical systems.
