43-943 50.8 mm Dia. Red Optical Cast Plastic Color Filter 400-700nm

The 43-943 is a 50.8 mm diameter color filter from Edmund Optics, designed for use in optical systems requiring red light filtration. This filter has a base shape of a circle, making it suitable for a wide range of applications. The filter is made of optical cast plastic, a material known for its durability and versatility in optical applications.

The filter's primary wavelength is 588nm, indicating its effectiveness in transmitting red light within the specified wavelength range of 400-700nm. This broad wavelength range makes it a versatile choice for various applications that require red light filtration.

The filter has a thickness of 1.5mm, which is considered thin in the context of optical elements. This thinness contributes to its lightweight nature and ease of integration into optical systems. The front and back of the filter are coated with EDM 43-942, a coating that likely enhances the filter's performance and durability.

The filter's shape is defined as a thin lens, suggesting that it may have some lens-like properties. However, without further specifications, it's challenging to determine the exact nature of these properties.
