47-504 25 mm Dia. Hard Coated Laser Line Longpass Filter 514.5nm

The 47-504 is a 25 mm diameter Longpass Filter, specifically designed for use with laser line applications centered at 514.5nm. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. The item data indicates that this filter features a circular base shape and is constructed from UVFS material, identified as "UVFS Mal- 1965".

The filter's primary function is to allow light transmission above a specified wavelength (588nm), while blocking or attenuating light below this cut-on wavelength (514.5nm). This is particularly useful in applications where selective wavelength transmission is required, such as in laser systems, spectroscopy, and optical imaging.

The 47-504 filter has a geometry defined by a 25mm diameter and a thickness of 3.5mm. The coating applied to both the front and back surfaces of the filter is identified as "EDM 47-504". This coating is likely hardened to increase the filter's durability and resistance to scratches and other forms of damage.

The filter's physical data indicates that it is cut on at 514.5nm and has no specified cut-off wavelength. This suggests that the filter is designed to block all wavelengths below 514.5nm, although the exact performance in this region may depend on the specific design and construction of the filter.
