This is a 17-285 UVFS Low GDD Dielectric Mirror, a high-quality optical component sourced from Edmund Optics. The mirror has a diameter of 25.4 mm and a thickness of 6.35 mm, making it suitable for a wide range of applications.
The mirror is designed for ultrafast lasers, specifically for the 1000-1060nm wavelength range. It features a UVFS (Ultrafast Laser) coating, identified as "uvfs mal- 1965", which is specifically designed to handle the high peak powers and short pulse durations associated with ultrafast lasers.
The front surface of the mirror is coated with "edm ult1000-1060", a coating that provides high reflectivity in the specified wavelength range. This mirror is categorized as a Dielectric Mirror, which means it utilizes multiple layers of thin film coatings to achieve high reflectivity.
The mirror's geometry is that of a Thin Lens, which can be beneficial in certain optical systems. The mirror's current status is "in stock", as indicated by its weblink, which is "https://www.edmundoptics.com/p/1000-1060nm-254mm-dia-x-635mm-thickness-ultrafast-laser-line-mirror/45006/".
