ANDY-25C-05 25 mm Dia. Optical Glass Unmounted Absorptive Neutral Density Filter for YAG Laser 1064nm

The ANDY-25C-05 is a specialized absorptive neutral density filter, designed for use with YAG lasers operating at a wavelength of 1064nm. This filter, offered by OptoSigma, is an unmounted circular filter with a diameter of 25mm and a thickness of 2mm, making it suitable for a wide range of 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 a unique coating, referred to as 'opt andy-05', which is applied to both the front and back surfaces of the filter. This coating ensures high absorption of the specific 1064nm wavelength, providing the necessary neutral density.

The filter's geometry, specifically its thin lens shape, suggests that it may have additional optical properties beyond simple light absorption. However, these are not specified in the provided data. The filter's catalog number, ANDY-25C-05, can be used to access more information or to make a purchase from the OptoSigma website.
