47-498 25 mm Dia. Hard Coated Laser Line Longpass Filter 325nm

The 47-498 is a 25 mm diameter Longpass Filter, specifically designed for use with 325nm laser lines. This filter, offered by Edmund Optics, is an essential component for applications involving laser systems, as it selectively transmits longer wavelengths while blocking shorter ones.

The filter is made from UVFS, a material with the catalog number MAL-1965. It has a base shape of a circle, ensuring uniformity in light transmission. The filter's geometry includes a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for various optical setups.

The 47-498 filter's physical data includes a cut-on wavelength of 325nm, meaning it begins to transmit light at this point on the spectrum. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than the cut-on.

The filter features hard coating on both the front and back, denoted as 'edm 47-498'. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for rigorous use in laser applications.

The filter's shape is classified as a Thin Lens, suggesting that it may have some light bending properties. However, this is not explicitly stated in the provided data, so further investigation would be required to confirm.

The 47-498 filter is currently in stock and can be purchased directly from the Edmund Optics website, as indicated by its weblink status. This filter is a reliable and efficient solution for applications involving 325nm laser lines.
