14-518 50 x 50 mm SCHOTT RG645 Red Colored Glass Longpass Filter 645nm

The 14-518 is a 50 x 50 mm SCHOTT RG645 Red Colored Glass Longpass Filter, designed to transmit light with wavelengths longer than 645nm while blocking shorter wavelengths. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.

The filter is made of color glass, a type of optical filter that uses colored glass to block specific wavelengths of light. It has a base shape of a rectangle, making it suitable for use in various optical systems. The filter has a thickness of 2mm, providing durability and stability.

The physical data of the filter indicates that it is cut on 645nm, meaning that it starts to transmit light at this wavelength. The cut off is 0, indicating that it blocks all wavelengths shorter than 645nm. This makes it ideal for applications where longpass filtering is required.

The filter features a coating on both the front and back surfaces, identified as 'edm 14-518'. This coating could enhance the filter's performance, such as improving its durability or optical properties. However, the specifics of this coating are not provided in the item data.

The filter's shape is described as a 'Thin Lens', suggesting that it may have lens-like properties. However, without additional information, it is difficult to determine the exact implications of this shape.
