ANDY-25C-20 25 mm Dia. Optical Glass Unmounted Absorptive Neutral Density Filter for YAG Laser 1064nm
The ANDY-25C-20 is a high-quality Neutral Density Filter, specifically designed for use with YAG Lasers operating at a wavelength of 1064nm. This filter, offered by OptoSigma, is a circular unmounted component with a diameter of 25mm and a thickness of 2mm, making it a versatile option for various optical applications.
The filter's primary function is to reduce the intensity of the incident light without altering its color composition. This is achieved through the use of absorptive coatings on both the front and back surfaces, specifically the "opt andy-20" coating. This coating ensures a high level of neutrality, ensuring the filtered light remains true to its original color balance.
The filter's geometry is shaped as a thin lens, which can be beneficial in certain optical systems where minimal thickness is required. The catalog number for this filter is ANDY-25C-20, and it can be found on the OptoSigma website, where it is currently in stock.
