49-035 12.5 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=1.5mm 950nm

The 49-035 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model has a diameter of 12.5 mm and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.

The filter is manufactured by Edmund Optics, a leading supplier of optical components, and is identified by the catalog number 49-035. It is available for purchase directly from the vendor's website, where it is currently listed as in stock.

The 49-035 features a traditional coating on both the front and back surfaces, denoted as 'edm 49-035'. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The cut-on wavelength for this filter is 950 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength, on the other hand, is 0 nm, indicating that it blocks all wavelengths shorter than 950 nm.

This filter is designed to fit a Thin Lens shape, and its material ID is UVFS MAL-1965. The item's geometry, including its diameter and thickness, contribute to its optical performance and compatibility with various optical systems.
