20CGA-590 2 x 2 in Square Colored Glass Alternative Longpass Filter 590nm

The 20CGA-590 is a Longpass Filter from MKS/Newport, designed with a base shape of Rectangular and a Thin Lens shape. This filter is characterized by its 50.8 x 50.8 mm dimensions and 1.1 mm thickness, making it a substantial yet manageable component for various optical applications.

The filter's primary function is to allow light transmission above a specified wavelength while blocking lower wavelengths. In this case, the 20CGA-590 has a cut-on wavelength of 590 nm, meaning it starts transmitting light at this wavelength and above. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths below 590 nm.

This filter features a coating on both the front and back surfaces, identified as 'new 20cga-590'. This coating enhances the filter's performance and durability, ensuring optimal functionality in its intended applications.

The 20CGA-590 is made from UVFS Mal-1965, a material known for its optical properties and versatility in various applications. The filter is currently in stock and available for purchase through the provided weblink, which has been verified as valid.
