241-5003 50.8 mm Dia. BG3 Color Glass Filter; t=3mm

The 241-5003 is a color glass filter, part of the extensive catalog offered by EKSMA Optics. This filter, with a diameter of 50.8 mm and a thickness of 3 mm, is designed for use in various optical applications.

The filter's type is color glass, which is known for its ability to selectively transmit or block specific wavelengths of light. In this case, the filter is designed to work at a wavelength of 588 nm, making it suitable for applications that require the manipulation of light in this spectrum.

The filter's geometry is defined by its diameter and thickness. With a diameter of 50.8 mm, it is suitable for use in systems with similar aperture sizes. The thickness of 3 mm provides structural integrity while also potentially influencing the filter's optical properties.

The filter's coating is another crucial aspect of its design. Both the front and back surfaces of the filter are coated with "eks 241-2003", a coating that likely enhances the filter's performance and durability.

The filter's shape is described as a "Thin Lens", suggesting that it may have some lens-like properties, such as focusing or diverging light. However, without more specific information, it's difficult to say for certain.
