20CGA-495 2 x 2 in Square Colored Glass Alternative Longpass Filter 495nm

The 20CGA-495 is a Longpass Filter from the reputable vendor MKS/Newport. This filter is specifically designed with a 2 x 2 in square shape, making it suitable for various optical applications. The filter's base shape is rectangular, and it is made from a high-quality material identified as UVFS Mal-1965.

The filter's primary function is to allow light transmission above a certain wavelength while blocking lighter wavelengths. In this case, the cut-on wavelength is 495nm, and the cut-off wavelength is 0nm. This means that the filter will allow the transmission of light with a wavelength of 495nm and longer, effectively blocking shorter wavelengths.

The geometry of the filter is well-defined. It has a width of 50.8mm, a height of 50.8mm, and a thickness of 1.1mm. This precise geometry ensures a consistent performance and easy integration into optical systems.

The coating on both the front and back of the filter is 'new 20cga-495'. This coating is designed to enhance the filter's performance and durability, ensuring reliable long-term use.

The filter's shape is thin lens, which is a common design for optical elements. This shape allows for efficient light transmission and minimal distortion, making it an excellent choice for a wide range of optical applications.
